# 329 installs, #31 on Germany's Top Grossing chart: a tarot creator moved her members into an app

**What it is:** The personal app of German tarot creator Ute Märker: natal charts, life-number numerology, a daily card, a mood diary, plus her videos. Premium is 7.99 €/month or 59.99 €/year.

**Why it took off:** She has a hundred thousand followers on Instagram and TikTok and already sold premium memberships at a high price. A "sign up and get it free" Halloween special pulled fans into the app. Germany's Lifestyle Top Grossing chart has a low bar, so a few dozen subscriptions can chart.

**C** **How you could follow** Don't build your own astrology app. Build one for a niche creator who already sells monthly memberships: a daily-use app with generic chart and numerology modules, filled with the creator's content, linked to her website member accounts, with revenue share.

Grade C: the volume comes entirely from Ute herself and her paying old fans, so followers can't replicate it. Anyone can build the app itself, but putting it in the store brings no one in. What's worth learning is the approach of "building an app for a creator," which is small in scale: one creator only supports dozens to hundreds of subscriptions. Few people know about it yet

Data (updated daily) · first launch 2026-09-30 · 11-07 installs 329

Android · Total installs worldwide

Data 2026-11-02 → 2026-11-07 (6 days, 6 observations). Google's detail page only refreshes install counts every other day, so a flat day doesn't mean nobody installed.

In Essen, tarot reader Ute Märker announced her app "Sternklar" on Instagram in Oct 31. A week later it had only 329 installs on Google Play, yet it ranked #31 on Germany's Lifestyle Top Grossing chart. This isn't an app that grew in the store on product strength. It's a creator who already sells 29 € and 69.90 € monthly memberships, routing her followers into her own app. This piece covers what it is, why so few installs could chart, where the money comes from, and whether you can take this path.

### A Halloween Reel

Oct 31, Instagram account @ute.maerker.tarot posted a Reel. The caption's first line is "Wer in deinem Leben trägt eine Maske?" (Who in your life is wearing a mask?). She uses the ship, book, bird and four-leaf clover from a Lenormand deck to tell the story: "This person keeps their distance, you don't know the whole story, what they say and what they do don't match." Then she turns the conversation:

> "I'm giving you the Halloween special for 12 signs, in my new app Sternklar, available on Android from today... Download Sternklar, sign up and log in, and the special is yours. The iPhone version is coming soon, for now you can watch on the website."

The last line reads "save this and send it to the friend who knows who you mean." The comments are a row of "Danke ❤️."

This Reel tells the whole story: she has an audience that listens to her pull a card every day, and she trades an exclusive piece of content, visible only in the app, for them downloading and signing up.

### What it is

The store page opens with "Sternklar ist dein ruhiger Raum für Astrologie und Numerologie. Ehrlich, klar und ohne Versprechen, die niemand halten kann." (Sternklar is your calm space for astrology and numerology. Honest, clear, and without promises nobody can keep.)

Put plainly, it is **a German astrology and life-number tool wrapped in the voice of a real fortune teller** . The free tier includes sun, moon and rising signs calculated from birth data, life-number and personality profiles, "Ute's daily card," moon phases, a tap-based mood diary, plus her free videos and a weekly "question card." Premium unlocks full chart readings, compatibility, personal yearly numbers, weekly spreads and deeper diary analysis.

Pricing is 7.99 €/month or 59.99 €/year, and the website says "no ads, no tracking." The developer listed is Ute Märker herself, based in Essen (Google Play store page, 11-06).

### Metric

| Date | Total installs | German Lifestyle chart |
|---|---|---|
| 11-02 | 6 | Top Free 158 |
| 11-03 | 23 | Top Free #137, **Top Grossing #35** |
| 11-04 | 23 | Top Free #191, Top Grossing #34 |
| 11-05 | 297 | Top Grossing 33 |
| 11-06 | 329 | Top Grossing 31 |

Google Play installs and German chart positions, 11-02 to 11-06. The store page shows "100+" downloads, 22 reviews, rating 4.9.

- It was listed on Sep 30, but the public launch was announced Oct 31, and the first review is from Oct 31, so the month before was likely a closed test.

- **On the day it had only 23 installs, it still made the Top Grossing chart.** The revenue doesn't come from scale, but from a very small number of people willing to pay.

- 11-05 gained 274 installs in one day, source not found. Her most recent TikTok is 10-25, not TikTok; most likely an Instagram post or story, or an email to members (inference).

- Only charting in Germany so far, iOS version "bald" (coming soon).

### Why 329 installs can reach the Top Grossing chart

Because the bar for the top 30 spots on Germany's Lifestyle Top Grossing chart is already low. On the same day (11-06), at #13 was "Das Beste des Tages" with only 4,227 installs; #45 was fortunica from the long-running German fortune-telling platform adviqo, with 4.85M installs. On a small country's niche-category chart, a few dozen annual subscriptions can push a new app up.

One detail is easy to misread: **her existing members who install the app pay nothing, and aren't counted on this chart.** Her website is clear that members "log in to the app with the same account, and Premium unlocks everything," going through her own account system, not Google Play billing. So what pushed Sternklar onto the Top Grossing chart is fans who aren't members buying the 7.99 € or 59.99 € subscription directly in the app. Real paying user numbers aren't public, but based on chart position it's in the dozens (inference).

### Where users come from

All of it from her own audience.

- **Social following.** The official site says "over 100k people follow her on Instagram and TikTok". TikTok @utemaerker has 37.4k followers and 267k likes in total, and her October 12 zodiac monthly horoscope videos get 1.3k to 31k views each; YouTube has 2.8k subscribers and 325 videos (TikTok, YouTube, 11-06). She says she has been reading cards for more than thirty years.

- **Exclusive content for signups.** The Halloween special "Die Masken fallen" is only given away in the app, free on signup. The latest update note still says it: "A gift for all free accounts: a special, free to watch now." The homepage carries the same hook.

- **Site-wide funneling.** ute-maerker.de's homepage and membership page both lead with "Neu: Meine App Sternklar," and the membership page title now reads "Mitgliedschaft · Jetzt mit App."

- **No paid acquisition visible.** At this size, they don't look like they're running ads.

The comments are all her audience: "Ich liebe die Legungen von Ute und kann es immer kaum abwarten!" (I love Ute's spreads, I can never wait, 10-31); "Ute hat eine ganz tolle App ins Leben gerufen!" (Ute built a really great app, 11-02). Under each one is a reply signed by her, one saying "Wir werden die App stetig weiterentwickeln" (we'll keep developing the app). Someone is clearly helping with development behind the scenes, though who isn't known.

### Where the money comes from: a price pyramid

The app is only the cheapest layer of her business. Prices on the site (ute-maerker.de, 11-06):

| Layer | Pricing | What you get |
|---|---|---|
| Free | 0 | Daily card video, 7 days late, some spreads |
| Video single purchase | 1.49 € / 7.99 € each | Daily-card videos / standard member videos |
| **Sternklar Premium** | **7.99 €/month, 59.99 €/year** | Charts, numerology, synastry, and weekly spreads in the app; excludes her member videos |
| Premium membership | 29 €/month | Daily cards, weekly spreads, 12 zodiac half-monthly forecasts, meditations, video library, **with Sternklar Premium included** |
| Persönlich membership | 69.90 €/month, two-month minimum | Everything above, plus one personal spread every two months, limited spots |
| One-off personal spread | 119 € / 199 € / 299 € | She lays the cards herself for your question |

This table shows where the app fits in her business: it's a **daily entry point** . It reminds you every morning to check today's cards; non-members get the tools and some videos, and upgrade for the full set. For people already paying her 29 € a month, 7.99 € is cheap.

### Who it's competing with

| Product | Scale | How it differs from Sternklar |
|---|---|---|
| Co-Star, The Pattern | Tens of millions of downloads, mostly English | Pure algorithm, no real people |
| Obrio-family astrology apps like Nebula | Tens of millions, heavy paid acquisition | Paid consultations plus ads; Sternklar has spent nothing on ads |
| fortunica (adviqo, Germany) | 4.85M installs, #45 in German Lifestyle Top Grossing | A paid-call platform for many psychics |
| Questico / viversum, AstroTV | Long-established German phone and TV readings | Charged by the minute |
| Human Design App | 486k installs, #40 in German Lifestyle Top Grossing | Single-system tool, no real people |
| Generic horoscope apps (Astroportal, etc.) | Million-level | Free with ads |
| Patreon, Steady, Kajabi / Uscreen white-label apps | Very large | Generic membership platforms, no chart or numerology calculation |

Install counts and chart positions from Google Play, 11-06.

It isn't in the same race as these products. Others sell "fortune-telling"; it sells "Ute." Algorithm apps can't offer the voice of an acquaintance who has been reading cards for thirty years, and ad-driven platforms can't offer the security of "no guarantees." The ceiling, though, is Ute's follower count. Revenue isn't public, no press has covered it, and nobody on X talks about it; it circulates only within her own circle.

### If it were you

**C.** This is worth understanding, not worth copying. It took off because of Ute herself and members who were already paying her, which followers can't replicate. The app itself is a standard chart and numerology toolkit that anyone can build, but on its own in the store it would get no traffic. The real lesson is the play: build an app for an influencer who already has paying members, so it becomes something they open every day.

**Who it suits:** a team of 1 to 2 people that has shipped a subscription app and is willing to be an influencer's technical partner rather than build its own brand. Ideally you can reach a few creators in German, French, Italian or Japanese circles who already sell monthly memberships or one-to-one sessions in fortune-telling, meditation, yoga or handicrafts, and who will accept a revenue share.

**Who it doesn't suit:** anyone hoping to win an astrology app through organic store traffic or paid ads (that category has Co-Star and dozens of ad-driven apps with tens of millions of installs); anyone wanting one app to get very big (a creator's ceiling is her followers; Sternklar is in the range of dozens of subscriptions); anyone who can't land a creator and wants to make content alone.

**How to build it:** build a reusable foundation rather than a single app. Turn calculation features (charts, life-path numbers, daily cards, tap-to-select journaling) into generic modules, and swap in each creator's videos and voice. The key is to **link to the creator's website membership accounts** , so a member login unlocks everything, while non-members can buy a much cheaper in-app subscription. Charge a development fee plus a revenue share.

**How to acquire users:** your customer is the creator, not the end user. Start by finding fortune-tellers with 3 to 300k followers on Instagram or TikTok whose sites already sell monthly memberships or paid one-off sessions, and show them the Sternklar example. Copy Ute's launch playbook: a holiday special given away only in the app, free on signup; a Reel that says plainly "download, log in, it's yours"; download links across the whole website; and, since new apps face a low bar in small-country niche categories, use the week of chart exposure.

**When to move:** there's no rush, this isn't a window that will suddenly shut. But the nearest milestone is December's annual forecast and New Year spreads. A creator's app should ideally launch by mid-December to catch annual specials like "2027 annual forecast."

**Signs you've misread it:** ① one or two months after the iOS launch, Sternklar's installs climb to several thousand and it breaks into the top 20 in German Lifestyle Top Grossing, which would show a creator's own app has a higher ceiling than expected, and this play could move up to a B; ② conversely, if by December it drops out of the top 100 grossing, it means that was just the first week's enthusiasm from existing fans, and one creator can't sustain an app; ③ if platforms like Kajabi or Uscreen launch white-label templates with built-in chart and numerology calculation, the foundation loses its value.

## Why Sternklar Horoskop&Numerologie (de.utemaerker.sternklar) managed to break out

> Research date 2026-11-06. Data: googleplay library (chart_rank / app_profile, 2026-11-02 to 11-06), Google Play DE store page, ute-maerker.de, sternklar.app, Instagram, TikHub (TikTok).

### One line

It is the personal-brand app of German tarot/Lenormand fortune-teller **Ute Märker** (astrology + numerology + daily card + her videos). What "broke out" isn't the product itself, but **a creator with an existing paid membership base moved her fans and members into an app** : installs are only 329, yet it charted #31 on the DE Lifestyle Top Grossing chart. The reason is that the DE Lifestyle Top Grossing chart has a low bar, so a small number of high-ticket subscriptions can get on it.

### 1. How to read the data

- Installs (googleplay library, exact global cumulative): 11-02 6 → 11-03 23 → 11-05 297 (+274) → 11-06 329. The store page shows "100+", 22 reviews, rating 4.9.

- Charts (googleplay chart_rank): 11-02 DE Lifestyle Top Free 158; from 11-03 it appeared on the DE Lifestyle **Top Grossing** chart 35 → 34 → 33 → 31 (11-06). **It charted Top Grossing while it still had only 23 installs** , which means the revenue came from a very small number of paying users, not scale.

- Same-chart reference (11-06 DE Lifestyle Top Grossing): #13 "Das Beste des Tages" also has only 4,227 installs; #45 is adviqo's fortunica (4.85M installs). The bar for the 30 spots around DE Lifestyle Top Grossing is clearly low: a few annual subscriptions (59.99 €) are enough.

- Listing date 2026-09-30 (Play card data), but the public announcement "launching on Android today" was **2026-10-31** (Instagram Reel), and the earliest comments are from 10-31, so the month before was likely beta/review. The iOS version is "bald" (coming soon).

- Pricing (sternklar.app): free + Premium at 7.99 €/month or 59.99 €/year; no ads, no tracking.

### 2. Growth tactics (where users come from)

1. **The influencer's own following (confirmed)** : sternklar.app states "over 100k people follow her on Instagram and TikTok". TikHub found TikTok @utemaerker with 37.4k followers and 267k likes in total; her October 12 zodiac monthly horoscope videos get 1.3k–31k views each. YouTube @Ute-maerker has 2.8k subscribers and 325 videos. Main Instagram account: @ute.maerker.tarot.

2. **Instagram Reel + "get it free" hook (confirmed)** : 10-31 Halloween Reel "Wer in deinem Leben trägt eine Maske?": "I'm giving you the Halloween feature for 12 signs in my new app Sternklar, available on Android from today... Download Sternklar, sign up and log in, and the feature is yours. The iPhone version is coming soon; for now, check the website." Exclusive content is traded for downloads plus sign-ups. The latest version update note also says "a feature for all free accounts".

3. **Website membership funnel (confirmed)** : the ute-maerker.de homepage, membership page and shop page header all carry "Neu: Meine App Sternklar / Bei Google Play laden". Premium membership is 29 €/month, Persönlich 69.90 €/month (including a 119 € personal spread every two months), and **members get Sternklar Premium free** , unlocked by logging in with the same account. This is why existing paying members installed the app in bulk.

4. **Direct source of the 11-05 single-day +274: not verified** . The latest TikTok is 10-25, not TikTok; the most likely source is an Instagram post/story or an email to members (the website already lists the app as a membership benefit).

5. The comments show the developer replying to each one and fans writing long reviews ("Ich liebe die Legungen von Ute", "Ute hat eine ganz tolle App ins Leben gerufen"). These are organic fan praise, not solicited reviews; the commenters are all her audience.

6. Ads: not found in our library (the ad libraries only track listed products, so not finding it doesn't mean there were none); judging by the scale, it doesn't look like paid acquisition.

### 3. Competitors

| Competitors | Platform | Launched | Scale | How it differs from Sternklar |
|---|---|---|---|---|
| Co-Star | iOS/Android | 2017 | Tens of millions of downloads, mostly English | AI/algorithmic sarcastic astrology, no real person, social comparison; Sternklar is in German, with a real fortune-teller's voice and videos |
| The Pattern | iOS/Android | 2017 | tens of millions | Psychological-profile astrology; no spreads, no real person |
| Nebula / various Obrio-style astrology apps | iOS/Android | Around 2019 | Tens of millions, heavy paid acquisition | Paid consultations plus palm reading etc., driven by paid acquisition; Sternklar has zero paid acquisition and relies on a single persona |
| fortunica - Tarot & Wahrsager (adviqo GmbH, Germany) | Android/iOS | Years | 485 万安装,11-06 德区 Lifestyle 畅销 #45 | Platform-style paid call-in fortune telling with many readers; Sternklar is one person's brand app |
| Questico / viversum (adviqo), AstroTV | Web / app / TV | since 2000 | Long-established German phone/online readings | Per-minute call billing; Sternklar is subscription plus content |
| Human Design App(Healing Shore) | Android/iOS | — | 486k installs, #40 in German Lifestyle Top Grossing | Single-system tool; no real-person content |
| Generic "Horoskop" apps (Astroportal etc.) | Android/iOS | Years | Millions of users, ad-monetized | Free + ad-supported daily horoscopes; Sternklar has no ads and explicitly says it "doesn't predict the future" |
| Creator membership platforms (Patreon, Steady, Kajabi/Uscreen white-label apps) | Web/app | — | Big | Generic content subscriptions; Sternklar bundles her video membership with computed astrology tools (birth charts, life-number, journal) inside its own app |

### 4. Why it took off

- **An existing paying audience** : she already sells 29–69.90 €/month memberships and 119–299 € personal spreads, so her fans are already used to paying her; the app at 7.99 €/month is cheap for this group.

- **Membership benefits linked** : members get Premium free on the same login, the website funnels across the whole site, and already-paying users are migrated in bulk.

- **Exclusive content hook** : the Halloween feature exists only in the app (given on sign-up), converting social followers into registered users.

- **The DE Lifestyle Top Grossing chart has a low bar** : a few dozen paying users can reach the top 35, so "329 installs + Top Grossing 31" is not an anomaly but a structural feature of small-country category charts (the #13 on the same chart has only 4,227 installs).

- **Persona positioning** : German, "ehrlich, klar, ohne Versprechen" (honest, clear, no promises), "Karte des Tages von Ute", set apart from the hype-driven copy of paid-acquisition astrology apps, giving a sense of safety to German women in their forties and up (the commenter profile matches this, inferred).

### 5. Differentiation

The differentiation is "**a real-person psychic's personal brand + computed astrology tools + her video membership** " all in one: other astrology apps are either algorithm-only (Co-Star, Pattern), paid-acquisition plays (Nebula, fortunica), or generic membership platforms. That gap is why it can charge, but **its ceiling is set by her follower count** (~100k), so it isn't growing organically on product strength in the store.

### 6. How visible it is

Few people know about it yet. There is no public TrustMRR/revenue data, 0 posts mentioning "Sternklar" in the X corpus, and no press coverage; it only circulates in her own fan circle.

### 7. Copycats

None (no other same-name or obviously copied creator astrology apps found). However, the pattern of "a fortune-telling/tarot creator launching their own app" has precedents in both German and English markets, the bar is low, and it can be replicated.

### 8. Takeaways

- Find small-niche creators already selling high-priced memberships or one-on-one services (tarot, astrology, meditation, fitness, handicrafts) and build white-label apps for them: standardized tools (birth charts, life-number, journal) + the creator's videos + linked membership accounts.

- Use "app-only" holiday or limited-time content as the launch hook.

- Pick small-country category Top Grossing charts such as Germany; a few dozen subscriptions can get chart exposure.

### 9. Uncertain

- The specific trigger for the 11-05 + 274 installs (IG post/story, email or membership migration) is unverified.

- Actual paying user count and revenue are unverified; the Top Grossing rank may also partly come from in-app subscriptions outside membership.

- Who developed the app (outsourced / studio / in-house team) is unknown; "Wir werden die App stetig weiterentwickeln" implies a team.

- Performance after the iOS launch is unknown.
