"¿Te detiene un policía?": an Argentine-built $5 "lawyer in your car", 10 weeks in Mexico, 50k installs

Resguardo is a monthly subscription app. If you're driving in Mexico and get pulled over, in a crash, or your car is about to be towed, you press a button, a "advisor" video call comes up on your phone, tells you what to say and what not to sign, and the whole call is recorded to the cloud. It was built by an Argentine developer, launched in Aug 24, and by Nov 6 had 54,170 installs on Google Play, with 4,083 installs coming in 7 days. There's no new technology here; the model was imported from the US. Its growth rests on two things: Mexican drivers' anger at the police, and a TikTok account posting 18 videos a day. Below: how it acquires users, how it collects money, who it competes with, and whether you could build a version for another country.

A two-and-a-half-minute video

In Oct 31, the TikTok account @resguardo.app posted 19 videos in one day. The top one, as of Nov 6, has 600k views and 34k likes.

The first two minutes show a roadside confrontation: several police officers are trying to remove a car's license plate, and the driver says it's a magnetic plate that just fell off. A passing man steps in: "Don't take his plate, don't pick on him. A few days ago you tried to take 17,000 pesos from someone." The officer says he'll take him in, and he replies: "Take him wherever you want, I'll defend him."

The scene cuts, and the voiceover picks up: "The whole of Mexico is fed up with these guys... But what if I told you there's a way to make them stop trying to shake you down and apologize and walk away?" Then the product: an emergency button that connects you to a legal advisor, "who will tell the officer directly what your rights are," everything recorded, "stored in the cloud, can't be deleted." The last line: "Write info in the comments and I'll tell you more features."

Almost no one in the comments asks about the product; they're cursing the police. The most-liked comment (1,826 likes) is a sticker reading "the cops see another one coming"; the second most-liked says "you can sue them for robbery." Another video from Oct 31 shows a man being stopped and searched right after leaving a bank: 128k views, and the top comments say "there's no such thing as a routine check, get your facts straight!" and paste the full text of Article 16 of the Constitution: "No person shall be disturbed in his person, family, home, papers, or possessions..."

This is the ad: real footage of a police shakedown, plus a 30-second voiceover. The footage looks like citizen-recorded clips that have been circulating online, not footage the company shot itself (inference).

What it is

The product itself has little technology: video calls, recording, and emergency contacts are all off-the-shelf. The hard part is that someone has to answer video calls 24 hours a day.

A Play review from Sep 11 asks directly: "Which country are you in? From the wording I think it's Argentina. Good idea, but this is for Mexico." She wasn't wrong: the developer's replies to reviews use Argentine Spanish ("entrás a la app", "¡Manejá tranquilo!"). The website says "abogado real" (real lawyer), the Play description says "professional / assistant", and the footer adds that it "cannot replace legal representation." Whether the people answering the calls are licensed lawyers can't be determined from the outside.

How big it is now

No single day shows a sudden spike; the curve climbs steadily with growth gradually slowing. This shape usually reflects a fixed daily ad budget rather than one video going viral (inference).

Where users come from

TikTok volume. @resguardo.app has 35.5k followers, and by Nov 6 it had 78 videos, 73 of them posted in the five days from Oct 31 to Nov 4, 18–19 per day. Every title is the same line: "¿Te detiene un policía? ¿Tuviste un accidente? ¿No sabes qué hacer?" (Stopped by police? In an accident? Don't know what to do?), and every ending says "works across all of Mexico." The footage rotates, but it's always "police harassment footage + voiceover." Within the same batch, some got 600k views and others just over two hundred. This is a volume play, betting that some clip goes viral. A Nov 3 video with 235k views switched the voiceover to a lawyer's tone: "I'm a lawyer, and I'll be honest: not every officer has the authority to write you a ticket... It's on Google Play, and it's only 70 pesos."

Facebook / Instagram ads (inference, high confidence). Its Facebook page has 174k followers, more than three times the number of app installs. The same copy sits under a large batch of different posts and videos, the typical look of bulk-run ads. How many ads it runs and how much it spends can't be found.

Other. Local radio stations in the Tlaxcala and Puebla area of Mexico have posted what look like sponsored write-ups on Facebook (unverified). The store names in all three languages include "legal protection," capturing the matching search terms. No one in the startup scene has mentioned it: about 90 posts on X in the past 0 days, and no press coverage or public revenue figures.

Where the money comes from: off-store Stripe + activation codes

The app is free to download. To pay, you go to resguardoapp.com, click the button to pay by card via Stripe, receive an activation code by email, then return to the app, tap "Tengo un código" (I have a code), and enter it. On iPhone, the web version uses the same code.

Annual billing is 10 months paid for 12 months of use. The site also sells a "one-year protection" gift code, paid in full and sent to the recipient via WhatsApp, so children can buy it for parents. Brazil uses a different brand, Testemunha na Estrada, at R$14.90 a month; its copy and layout map line-for-line onto the Mexican site, so it's probably the same team (inference).

Collecting this way has two advantages. First, you avoid Play's 15–30% commission, and the savings go toward buying traffic. Second, on iPhone it never goes through Apple's review at all. What it's really selling is insurance; the site's pitch is "cheaper than a meal out, and best never used." Most subscribers won't need it more than once a year, which is what makes the 24-hour staffing cost sustainable (inference, no data).

Paying users and revenue aren't visible from outside: it has never charted in the top grossing lists, and the money is collected off-store.

Who it's competing with

The US has already proven people will buy this. In Spanish and Portuguese markets I couldn't find a second product selling a one-tap video-to-lawyer subscription. Resguardo is basically carrying TurnSignl over to Latin America: one-third the price, and it expands the scenarios from police stops to tow trucks, tickets, and road rage. It's also expanding abroad on its own. Sites and Facebook pages are up for Brazil and the US ("all 50 states"), but the US TikTok account only posted 4 videos and has 0 followers as of November.

If it were you

The short take: worth following, but pick a different country. Find a market where drivers fear cops and getting shaken down, and build a local "lawyer in your car" subscription, using live video plus voiceover clips to fill TikTok and Facebook. Don't go head to head with it in Mexico or Brazil.

Who it's for: 2–3 people. One person builds the app and web page (video calling can use an off-the-shelf SDK and be done in a week or two), one person cuts a dozen-plus short videos a day and manages ads, and you need someone who can find and manage a local team of call-center lawyers, such as part-time attorneys or law students on shifts. Ideally you're from that country yourself.

Who it's not for: anyone without contacts in the local legal community (the staffing is the hard barrier and the biggest cost); anyone scared of compliance risk (many countries don't allow non-lawyers to give legal advice, and there are rules on recording calls); anyone who only wants pure software and doesn't want to manage people.

How to do it:

• Pick a country: somewhere police shakedowns and roadside checks are everyday talk. In Latin America, Colombia, Peru, Ecuador, Guatemala; in Southeast Asia, the Philippines and Indonesia; also Nigeria and Kenya (my guess, not systematically checked). Before launching, search local TikTok for "police + extortion" videos and see how many views they get, to check whether the mood is there.
• Copy the product as it is: one-tap video, cloud recording, emergency contacts. Start with Android plus web, take payment off-store, and link it up with activation codes. Price it at roughly the cost of one local meal, around $2 to $5 a month.
• Its weak spot is trust. Mexican users are already asking "which country are you even in" and "is the person who picks up actually a real lawyer?" Spell out the lawyers' bar license numbers and the local team, and don't use a "social news" tone (a September comment complained it didn't seem serious enough). Those are places you can beat it.

How to get users: copy its ad formula. Use footage of local people filming police hassling them (watch copyright; better to get the original creator's permission or act it out yourself), follow with 30 seconds of voiceover, "there's an app that makes him apologize to you," and end with "comment info." Post a dozen-plus a day, and put budget behind whatever performs on Facebook and Instagram. Add a family plan and gift codes so parents can buy one for a newly licensed kid, and kids can buy one for their parents.

When to move: its Brazil and US sites are already built, and the next step is probably Spanish-speaking countries like Colombia or Argentina. Launching in a country it hasn't entered and getting the first paying customers within six months is the safer bet. If you wait until mid-2027, those Spanish markets will likely already have it or a copycat (my guess).

What would mean you read it wrong:

• If a month of posting videos in one country doesn't get a single one past 100k views, people there either aren't that angry at the police or don't believe an app can help.
• If conversion to paid never takes off, or people cancel fast (this kind of "insurance" dies when users don't use it for three months), its steady growth in Mexico may depend entirely on ongoing ad spend.
• If a local bar association or regulator says "non-lawyers may not give legal advice," or the platforms start pulling these ads, the window closes.
• If Resguardo's weekly Google Play installs drop below one or two thousand by year end, even the original isn't keeping up.
