# Pulled over by police, your phone has a lawyer: an Argentine moved a US business to Mexico and sells it for $5 a month

**What it is** Press one button when something goes wrong while driving, and a person on video joins to tell you what to say and what not to sign. Calls are recorded throughout. Billed monthly.

**Why it took off** It brought the US TurnSignl model to Mexico, a market nobody was serving, and priced it at $5. Mexicans are angry about police, so a "what to do if police stop you" ad ran a dozen-plus times a day. Collecting payment off-store through Stripe avoided the cut and funded paid acquisition.

**B** **How you could follow** Pick a country it hasn't entered where police and traffic disputes are common. Start with a landing page, WhatsApp video, and one or two on-duty lawyers to test willingness to pay. Run Facebook and TikTok ads built on local enforcement clips with a hook line. Collect payment off-store and sell a family plan and gift codes.

Grade B: blank market, nobody talking about it, the playbook is clear, but paying users are completely invisible. The part you could copy is stuck on 24-hour lawyer coverage and legal compliance, and the original author is already expanding into Brazil and the US. Word is spreading in small circles.

An Argentine solo developer built an app that in Mexico is called Resguardo, meaning "safeguard". You get pulled over by the police, get in a crash, or have your car towed, you press one button, and someone on the other end video-calls in, watches the scene with you, tells you what to say and what not to sign, and the whole call is recorded. It launched Aug 24, and by Nov 6 it had 54k installs on Google Play, climbing steadily with no sudden spike. The model already exists in the US. This one moves it into a market nobody has touched, undercuts on price, and fills the funnel with ads that hit on fear.

### 18 posts a day, captions not changed at all

In Nov 3, the TikTok account @resguardo.app posted 18 videos in one day, and 4 more in Nov 18. The captions all say the same thing:

> ¿Te detiene un policía? ¿Tuviste un accidente? ¿No sabes qué hacer? (Stopped by a cop? Had an accident? Don't know what to do?)

followed by "Use our app, a lawyer on video for 24 hours." The top video was posted in Nov 3, with 235k views. The comments barely talk about the app; they rage at the police: "That's abuse of power, article 16 of the constitution says no one can touch your belongings without a court order", "Police aren't allowed to put their hands in your bag", "This is how it is all over Mexico". Mixed in are rows of comments that just say one word: "info", "Información".

The 59 videos you can pull from the account were all posted between Oct 31 and Nov 4, totaling about 950k views (TikTok profile data, 11-06). People watch the videos because Mexicans are already furious at the police. The app just hangs a line on that anger.

### What it actually sells

Open the site resguardoapp.com and the first screen reads "In hard moments, you are not alone", with three lines below: 24/7, a person with you within 1 minutes, and 100% of calls recorded and stored. It says it covers these situations:

- Police stops: what you must show, what you must comply with, what you can refuse;

- Car accidents: what to photograph in the first few minutes, how to talk to the other driver;

- Towing: what to check before the car is taken, so you don't pay for damage someone else caused;

- Tickets you dispute: understanding what the ticket says, not missing the appeal deadline;

- Roadside arguments: "Many scenes calm down just because there's a witness on the other end of the phone";

- Long-distance driving and unfamiliar cities.

Usage is three steps: press "I need help", a lawyer joins a video call, and after it ends you get advice and the recording.

The problem is the word "lawyer". The FAQ on the site says "professional lawyers in your region"; the Play Store description only says "profesional" and "asesor" (advisor); the small print on the pricing page says "does not include court representation". From the outside, there's no way to tell whether the person answering is a licensed lawyer.

### Where the money comes from: collected off-app, the app only takes a code

| Tier | Pricing (website, 11-06) | Extras |
|---|---|---|
| Basic | US$5/month, family plan 4 accounts US$10 | 24 hours of video, GPS-tagged recordings |
| Premium | US$14.99/month | Follow-up through case closure, ticket appeals, contract photo review |
| Total | US$29.99/month | 5 accounts, priority access, an assigned lawyer |

Annual billing is 10 months of fees for 12 months of use. Every paid button on the site links to Stripe: after paying, you get an activation code by email and enter it in the app under "Tengo un código" (I have a code). There's no iPhone app; iOS users use the web version. This skips the 15%–30% cut Google and Apple would take, and iOS needs no app review.

Another trick is the gift code: "Gift a year of protection", paid upfront, and the recipient gets the code sent to them over WhatsApp, "nothing to pay". The scenarios on the site are "for the kid driving at night, for your parents".

The FAQ has a strong sales line: "We hope you never need it, like insurance. The difference is it costs less per month than a meal out." What it sells is peace of mind. If most subscribers never call once in a year, the staffing cost can be covered (inference, no data).

How many people pay can't be seen: it has never charted on any top list, and the money goes off-app.

### Where users come from

**Facebook / Instagram, the main channel (inference, high confidence).** The Facebook page resguardo.ok has 174k followers, over three times the app's installs. The "¿Te detiene un policía?" copy above appears under many different posts and videos, the way one batch of creative gets pushed out. How many ads run and how much is spent is unknown.

**TikTok for volume.** These are the 36 videos from the start. 35.5k followers, 99 posts, titles stuffed with "México", such as "Abogado por videollamada 24 horas en México" (lawyer by video call 24 hours in Mexico). Whether it's paid boosting or organic reach can't be told.

**Local radio.** A radio station in Tlaxcala / Puebla posted an introduction on Facebook that reads like a press release.

**Three names for one package.** The same app is called Resguardo - Protección Legal in the Spanish store, Retaguarda - Proteção Legal in Portuguese, and Rearguard - Legal Protection in English, so every language picks up the "legal protection" search term.

The install curve also fits a fixed daily-budget approach: about 900 a day in September, 650 in October, and 550 in early November (AppstoreSpy estimates plus public Google Play data), steady throughout and gradually slowing. On the charts, it ranked #69 on Mexico's Lifestyle Free chart (11-06), and Brazil's same chart had it at 146.

Nobody on X, Reddit, or tech media has mentioned it, and no revenue is public. People outside the circle barely know it exists.

### Who it's competing with

| Who | Where | Compared with alternatives |
|---|---|---|
| TurnSignl | US, since 2020 | Nearly identical: a video call with a lawyer plus recording during police stops, covered by PBS, with some cities paying for residents. Only practicing US lawyers. |
| Attorney Shield | US (Florida), on iOS since 2024-03 | Similar, from US$16/month, only covers law enforcement encounters; 159 ratings on the US iOS store |
| LegalShield | US and Canada, since 1972 | Established prepaid legal service; emergency lawyers are reached by phone, not by video of the scene; expensive plans |
| MexLegal | Web | A lawyer hotline sold to American tourists visiting Mexico, from $29.95 |
| Legal aid bundled with car insurance | Individual insurers | Only available with car insurance, you call to report, and no one watches the scene with you |

Put simply, Resguardo is a Latin American, cheaper version of TurnSignl. In the Spanish and Portuguese stores, I couldn't find a second app doing "one tap, video call a lawyer"; what turns up is mostly AI legal Q&A.

It is already expanding on its own: in Brazil there's Testemunha na Estrada ("Witness on the Road"), with copy that maps line by line to the Spanish version, at R$14.90/month; in the US it has opened a Rearguard website and a new Facebook page reading "all 50 states", but the TikTok @rearguardapp has only 4 posts and 0 followers. The read is that these are several brands from one team (inference, owner not verified).

### Its weak spots

- **Local feel.** One Sep 11 review with 8 people marking it helpful: "I downloaded the app, and from the wording I think you're in Argentina. Good idea, but this has to be built for Mexico." The Spanish Play description really does use Argentine wording ("tenés", "Descargá"), which Mexicans spot immediately. The same review adds "That kind of tabloid-style opener is unnecessary; this kind of service needs to feel trustworthy."

- **Who picks up the call.** The site says lawyer, the store says advisor, the fine print says no court representation. Whether the staff are licensed lawyers, which country they're in, and how many there are, nobody knows.

- **Compliance.** Mexico and Brazil have rules on non-lawyers giving legal advice and on recording calls; at scale this could draw regulators.

- **Its own site contradicts itself.** The homepage says the family plan covers "up to 3 accounts", the pricing page says "4 accounts". A small thing, but it shows one person rushing.

### If it were you

**B. The opportunity is real, but the part you could copy is gated by staffing, not code.** A button plus a video call plus recording can be built in a week. The hard part is having someone who knows local law available within a minute, every day for 24 hours, and then turning fear into ads in a market that resents the police.

**Who it suits** : someone whose country is not Spanish- or Portuguese-speaking, where "police shakedowns and traffic disputes are common and US-style legal service hasn't arrived", who has one or two licensed lawyer friends willing to staff shifts by the hour, and who will run Facebook or TikTok ads. Markets like Colombia, Peru, the Philippines, Nigeria, and Indonesia are worth checking first (inference, not verified one by one).

**Who it doesn't suit** : anyone who can only write code and can't line up lawyers to staff it; anyone aiming to go head-to-head in Mexico or Brazil, where the original author already is and has a head start; anyone going head-on into the US, where TurnSignl and Attorney Shield have practicing-lawyer and press backing.

**How to build it** : skip the app at first. A landing page plus WhatsApp video is enough to test. Price it the way it does, around "cheaper than a meal", at $3–$5 a month, and also sell a family plan and a one-year gift code. Collect payment off-app and enter the code in the app. Start with one or two lawyers on rotating shifts, and pay them with Premium services like "follow-up" and "ticket appeals". Write the tone and terms in the local language, and avoid the slip-ups it makes.

**How to get users** : the creative is local enforcement-clash clips already spreading online, with one line: "Stopped, don't know what to do?" One script cut into a dozen variants, a dozen-plus posts a day, and everyone who comments "info" gets a DM. Test with a small Facebook budget, and only scale creative where acquisition cost is under one month's subscription. The family plan and gift codes let children buy for their parents.

**Deadline** : it is already expanding into Brazil and the US. Take a country it hasn't entered and get the first paying users within three months (before February 2027); later than that, it translates the same creative and does it cheaper than you.

**What would show you misread the market** : ① after a month of testing, under 1% of people who reach the landing page pay, meaning people want to watch police get roasted but won't pay for it; ② the local bar association or regulator says "non-lawyers can't give legal advice", or Resguardo itself is named by Mexican regulators; ③ Resguardo's Facebook and TikTok stop posting in early 2027 and the install curve goes flat, meaning paid acquisition stopped paying off and even the original author couldn't sustain it; ④ the reverse: if Rearguard grows in the US, it shows the "low price plus fear creative" approach works even in mature markets, and the window is opening in several countries at once.

**Research notes: competitor table, acquisition evidence, full research report**

Competitors

| Name | Where | Launched | Scale | How it differs from this one |
|---|---|---|---|---|
| TurnSignl | iOS | 2020-2021 | US-based, with PBS coverage and municipal partnerships | The same model, but only for US-licensed lawyers and law-enforcement stops. Resguardo covers Latin America, is cheaper, and covers more scenarios. |

| Roadside assistance / legal aid bundled with car insurance | Big-company features | — | Big | Only exists with car insurance. You call in the incident, and there is no video of the scene to get help in real time. |

Where users come from

- Inferred **Facebook/Instagram ads** : the FB page resguardo.ok has 174k followers, far more than 54k installs. The same copy shows up under many different post / video IDs. A US page posts the same video set. The metaads library doesn't track this page.

- **Confirmed** **TikTok mass posting** : @resguardo.app has 35.5k followers and 99 posts. 11-03 and 11-04 post 18 videos a day with identical copy. The latest 40 videos total about 820k views, with the top one at 235k (TikHub).

- **Confirmed** **Mexican local radio / sponsored content** : Radio 1370AM Peligrosa (Tlaxcala/Puebla) posted an app introduction on Facebook.

- **Confirmed** **Store search + localized titles** : the same package name shows as Resguardo - Protección Legal / Retaguarda - Proteção Legal / Rearguard - Legal Protection depending on language.

## Rearguard / Resguardo / Retaguarda - Legal Protection (com.resguardo.resguardo) research report

Research date 2026-11-06. Channel: Google Play. Developer NortekDesarrollos. The Play developer info lists an individual, MARTÍN EZEQUIEL LOVERA, with an address in Buenos Aires, Argentina (CABA). Support email airelimpio.ok@gmail.com (source: Play Mexico listing, es-419).

### One line

A monthly-subscription app for "one tap to a live person by video" when driving into trouble: police stops, car accidents, towing, tickets, road rage. You tap a button, and an "advisor / lawyer" joins by video to see the scene, tell you what to say, and what not to sign. Calls are recorded as evidence. Built by an Argentine indie developer. The main market is Mexico (Spanish brand Resguardo), Brazil uses the Portuguese brand Retaguarda, and they are also pushing the US (English brand Rearguard, "all 50 states").

### Data

- Installs: 54,170 (googleplay library, 2026-11-06); 7 day +4,083; rating count 247 → 283 (10-29 → 11-06). The Play page shows 4.7 stars, 284 reviews, 50K+.

- Curve since launch (googleplay library app_day_ext, AppstoreSpy estimates): 08-31 about 3.4k → 09-10 about 10k → 09-18 about 20k → 10-01 about 30k → 10-24 about 49k → 11-06 54k. That works out to roughly 900 installs a day in September, 650 in October, and 550 in early November. There's no single spike day; it climbs steadily and is slowing down. It looks like continuous paid acquisition, not one viral moment.

- Charts (googleplay library chart_rank): Mexico LIFESTYLE Top Free 89 (10-29) → 134 (11-01) → 69 (11-06). Brazil LIFESTYLE Top Free 113 → 146, dropping out of the top 200 for a few days in between. Only charted in the mx and br stores, never on Top Grossing.

- Pricing (websites resguardoapp.com/premium and rearguardapp.com/premium): Basic US$5/mo (family plan 4 accounts at US$10), Premium US$14.99/mo (follow-up, ticket appeals, contract review), Total US$29.99/mo (5 accounts, priority access, a named lawyer). Annual billing works out to paying for 10 months and getting 12. The Brazilian brand Testemunha na Estrada charges R$14,90/mo, family plan R$24,90 (testemunhanaestrada.com). In-app purchases on Play range from $3.99 to $79.99.

- **Payments happen off-platform** : every pay button on the website is a Stripe link (buy.stripe.com). After paying, you get an activation code by email and redeem it in the app via "Tengo un código / I have a code". There's no native iPhone app; iPhone users use the web version at resguardoapp.com/app. This avoids Play's 15–30% cut and Apple review. The site also sells gift codes for "a year of protection" (paid up front, sent to the recipient via WhatsApp).

### Competitors

| Name | Where | Launched | Scale | How it differs |
|---|---|---|---|---|
| TurnSignl | iOS/Android, US | 2020–2021 (Minneapolis; covered by PBS and police1) | US-based, with media coverage and municipal partnerships (Brooklyn Center offers it free to residents) | The same "video call with a lawyer + recording during a police stop" concept, but US-only, with US-licensed lawyers. Resguardo is going after the gap in Latin America. |
| Attorney Shield | iOS/Android, US (Florida) | iOS 2024-03 | iOS US store rating count 159 (iTunes lookup) | Same category, from US$16/mo; US law-enforcement scenarios only |
| LegalShield | iOS/Android/web, US and Canada | From 1972/yr (Pre-Paid Legal) | Established prepaid legal service with millions of members (unverified) | 24/7 emergency lawyers are phone calls, not video of the scene. The bundle is a full legal plan, so it costs more. |
| MexLegal | Web, Mexico / US tourists | Not verified | Small | A 24/7 lawyer hotline for US tourists heading to Mexico, from $29.95. Not a low-cost subscription for local drivers. |
| Local Mexican law firms offering "online / video consultations" (e.g. abogadosnayarit.com/virtual) | Web / WhatsApp | — | Scattered | You have to book an appointment. It isn't one-tap access at any time. |
| Roadside assistance / legal aid bundled with car insurance | Big-company features | — | Very large | Only exists with car insurance. You call in the incident, with no video of the scene. Resguardo positions itself as a standalone subscription "cheaper than a meal out". |

Bottom line: this category already has several players in the US (TurnSignl, Attorney Shield, LegalShield). **Resguardo is essentially bringing the US TurnSignl model to Latin America and pricing it lower** . In our googleplay library (apps that have charted), searches for abogado / advogado / legal help / lawyer find no direct competitors in Spanish or Portuguese markets. The closest are AI legal Q&A apps like Rocket Lawyer and Vikk.

### Growth tactics (evidence)

1. **Facebook / Instagram ads (main channel, strong inference)** : the Facebook page resguardo.ok has **174k followers** (read via Jina, 2026-11-06), about three times the app's 54k installs. The same copy, "¿Te detiene un policía? ¿Tuviste un accidente? ¿No sabes qué hacer? Con nuestra app tienes respaldo legal por videollamada…", appears under many different post / video IDs (posts 122124189471415805, 122124359103415805, 122124542049415805, videos 1654111559683207, etc.). That's typical of one creative batch-posted across many placements. The US brand opened a separate FB page, "Rearguard: Legal Help" (61595283606124), and 61595563884527 (from the ID, a page created in 2026), posting the same "Available in all 50 U.S. states" video set. Our metaads library doesn't have these pages (it only tracks a fixed list of products), so we can't get the active ad count.

2. **TikTok mass posting** : @resguardo.app has 35.5k followers, 99 posts, and 280k likes (TikHub). Of the latest 40 videos, 11-03 posted 18 on one day, and 11-04 posted 18 more. The copy is identical across them, all built on the same hook. Those 40 videos total about 820k views, the top one at 235k. Titles all include "México" (e.g. "Abogado por videollamada 24 horas en México"). This is the "one script × many cut versions" volume play. Whether the TikTok posts are paid can't be verified.

3. **Mexican local media / radio** : the Tlaxcala/Puebla station Radio 1370AM Peligrosa.mx posted on Facebook about an app offering 24-hour video legal aid. It reads like sponsored content or a press release (unverified whether paid).

4. **Store search + localized titles** : the same package appears under different names by language: Resguardo - Protección Legal (es), Retaguarda - Proteção Legal (pt), Rearguard - Legal Protection (en). Each language picks up searches for "protección legal"-type terms.

5. **None** : searching X for resguardoapp / rearguardapp / "Resguardo app" returns 90 posts in the last 0 days (x-radar). No press coverage, no TrustMRR listing, no founder revenue disclosures, and no Reddit or HN discussion.

### Why it's working

- **The pain point is real in Mexico** : police shakedowns ("mordida"), disputes with the other party and insurers after a crash, illegal towing, tickets people can't understand. These are everyday anxieties for Mexican drivers. The ad hook "¿Te detiene un policía?" hits that fear directly, and single TikToks reach 10–230k views (TikHub).

- **Priced low, like insurance** : US$5/mo, and the website FAQ says it's "cheaper than a meal out; if you never need it, great; if you do, every cent was worth it." It sells peace of mind. Most subscribers rarely call, which keeps agent costs manageable. This is inference, not data.

- **Copying a model proven in the US into a market nobody is serving** : TurnSignl and Attorney Shield have shown in the US that people will pay for this format. In our library and search results, there are no equivalents in Spanish or Portuguese markets.

- **Closed loop from ads to off-platform revenue** : Meta / TikTok creatives drive users to Play or the website, payments run through Stripe to skip store fees, which means better margins and room to sustain paid acquisition. The smooth install curve with no spikes fits a fixed daily ad budget.

- **One creative set reused across three markets** : the three sites' copy nearly mirrors line for line (all use the same KM 01/02/03 layout), with the brand renamed per language. Expanding to a new country is cheap.

### Differentiation

Compared with US peers: **market (Latin America, mainly Mexico) + price (US$5 vs US$16 starting) + scope expanded from "law enforcement" to towing, tickets, road rage, and unfamiliar cities** . Compared with local Latin American law firms: **one tap, 24/7, video of the scene, recorded evidence, monthly subscription** , no booking needed. The differentiation that matters is "an empty market + low price + fear-driven ad creatives". The product features aren't new (it's video calling + recording + emergency contacts). The barrier is agent operations (24-hour availability). Whether a licensed lawyer actually answers is uncertain: the Play description says "professional / assistant", the website says "abogado real", and the footer states "no reemplaza representación legal" (does not replace legal representation).

### How visible it is / how many copy it

- Visibility: it's circulating in small circles. On the consumer side, the FB page has 174k followers and TikTok has 35.5k, but nobody in the startup or going-global circles is discussing it. 0 posts on X, no press, no public revenue.

- Copycats: none found by third parties. Brazil's Testemunha na Estrada (testemunhanaestrada.com) and the English Rearguard map line-for-line onto Resguardo's copy and layout, so it looks like **one team running multiple brands** , not outside copying (ownership not verified).

### Takeaways

- Find service subscriptions that are proven in the US but still empty in Latin America and emerging markets, then swap the language, cut the price, and copy them over.

- Fear-based scenarios + a one-line hook + many cut versions of the same script across TikTok / FB, posting a dozen-plus clips a day.

- On Android the flow sends users to the official site to pay via Stripe, then enter an activation code in the app; iOS uses the web version. This sidesteps store commissions and app review.

- The same package name gets renamed per language, one landing page template is reused across languages, and a "one-year protection" gift code lets children buy for parents and vice versa.

### Uncertain

- Paying users and revenue: no Top Grossing rank, and off-store Stripe payments are not visible to us.

- Who staffs the 24/7 seats, whether they are licensed lawyers, and what they cost; one user review questions it: "feels Argentine, not local to Mexico" (Play review, 2026-09-11).

- How many Meta ads it actually runs and how much it spends (the metaads library doesn't track this page); whether TikTok is paid or purely organic.

- US version progress: TikTok @rearguardapp has only 0 followers and 4 videos, and the US Facebook page was just created.

- Legal compliance risk: in Mexico and Brazil, non-lawyers giving legal advice, and recorded calls, could both draw regulatory scrutiny.
