See What Any App Really Earns, Then Rebuild It for the App Store (Sensor Tower + Blink)
The whole play from the video, in order: look up what an app really earns on Sensor Tower, copy its App Store link, and hand it to one Blink prompt that reverse-engineers the listing and rebuilds it as your own native iOS app. Then Blink puts it on the App Store for you. The full prompt is below, copy ready.
Step 1: See what any app really earns
Sensor Tower is the platform the app industry itself uses to spy on the competition. It publishes download and revenue estimates for basically every app on the App Store. Make a free account, search any app, and its profile shows estimated monthly downloads and revenue. They are estimates, not audited books, but they are the same numbers the industry pays serious money to watch, and they are directionally right.
Now browse the top charts in a category you actually understand. The pattern you are hunting: strong monthly revenue where the whole product is one clear job. Affirmation apps, habit trackers, sleep sounds, fasting timers, water reminders. The apps simple enough that your grandma could use them are the exact apps quietly doing numbers you will not believe.
Step 2: Pick your target and copy its App Store link
Before you commit, open the app's App Store page and read the reviews sorted by most critical. Angry reviews are market research someone else paid for. Ads everywhere, price hikes, a redesign everyone hates. Every recurring complaint is a feature your version does better, and the prompt below mines them automatically.
Two filters keep you out of trouble. Self-contained only: the content and features should live inside the app, so skip anything that depends on someone else's hardware, bank connections, or licensed catalogs. And one clear job: if you cannot describe the app in one sentence, neither can Blink.
Found it. Copy the App Store URL from the share button. That link is the only input the prompt needs.
Step 3: Open Blink and start a mobile app
Blink is the AI app builder this play runs on, and the reason it works at all: Blink has a real App Store pipeline. It writes a native iOS app in React Native, builds it in the cloud, and pushes it to TestFlight, no Mac, no Xcode, no terminal.

- Tap here to open Blink and sign up, it is free to start.
- Start a new project and tell it you are building a mobile app, not a website. The prompt below forces this too.
- Paste the prompt.
Step 4: Paste the full rebuild prompt
Replace [PASTE APP STORE URL] with the link you copied, then send. Blink opens the listing, studies the screenshots, the description, and the reviews, then rebuilds the entire product as a native iOS app with a design meant to make the original look dated. Give it time to finish, it is doing real work.
Here is the App Store listing of the app we are rebuilding: [PASTE APP STORE URL]
Open that link and study the entire listing before writing any code: the screenshots, the description, the feature list, the "What's New" notes, and the reviews. Pay special attention to the critical reviews. Every recurring complaint is something we will do better.
Now rebuild this app from scratch as a BETTER version, as a NATIVE MOBILE APP for iOS (React Native / Expo), not a website. I will publish it to the App Store through your publishing pipeline, so it must be App Store ready.
PRODUCT REQUIREMENTS
- Reverse-engineer the full product from the listing: its core screens, its onboarding flow, its content structure, and its subscription paywall exactly as the screenshots imply. Where the listing doesn't show something, infer what a top-grossing app in this category would do.
- Make it BETTER, not equal: fix the top 3 recurring complaints from the reviews.
- Purchases are MOCKED: the paywall looks and behaves real (weekly and yearly plans, free-trial badge, restore link), but subscribing just sets a local isPremium flag and unlocks everything. No payment SDK, no RevenueCat, no API keys.
- Bundle ALL content inside the app. Write it yourself at genuinely high quality, matching the type and depth of content the original ships. No CMS.
- All user data lives on-device in local storage. The app works 100% offline: zero backend, zero external APIs, zero keys, and no signup or login of any kind.
- Real local notifications for daily reminders, with the user picking times in settings.
DESIGN REQUIREMENTS — treat design as half the job; this is where we beat the original
- Before any code, define a real design system and apply it to every screen: one signature accent color with semantic color roles, a deliberate type scale pairing a characterful display font with a clean UI font (never default-looking type), a spacing scale, consistent corner radii and shadows, one cohesive icon set. No default-looking components anywhere.
- The look: premium and modern. Soft animated gradients that slowly drift, glass surfaces, layered depth, generous whitespace. Put the original app's screenshots next to ours and the original should look dated.
- Motion is part of the design: spring-physics screen transitions, content that fades and slides in on first render, buttons that compress subtly on press with haptic feedback, and one satisfying celebratory moment when premium unlocks or a streak extends.
- Dark mode and light mode both fully designed, not auto-inverted.
- Cover every state so no screen ever feels broken: first-run, empty, loading, locked-behind-premium, error.
- The bar: every single screen must be beautiful enough to screenshot straight into App Store marketing. If a screen would look out of place next to the top 10 grossing apps in its category, redesign it before moving on.
DO NOT BUILD: accounts or auth, backend, admin panel, social features, comments, home-screen widgets, camera or microphone features, web version.
Build the ENTIRE app in one pass without asking me questions. Make the best product decision wherever the listing is ambiguous. If any feature risks breaking the build, simplify it rather than leaving it broken. Every screen must work on the first run in the preview. When you finish, give me a short summary of what you built, the design direction you chose, and the three review complaints you fixed.Step 5: Test it like a customer
Blink gives you a live phone preview. Run the whole flow the way a stranger would: the onboarding quiz, the paywall, the core screen, a reminder, dark mode. One thing to know: the paywall is mocked on purpose. It looks and behaves completely real, but subscribing just unlocks premium on the device, so you can demo the full app with zero payment setup and charge nothing by accident. When you want real money later, Blink wires actual in-app purchases during App Store setup.
Anything that feels off, tell Blink in plain English and it fixes it. Spend your revisions on the home screen. That one screen is the product.
Step 6: Put it on the App Store
This used to mean a Mac, Xcode, and a week of provisioning pain. Now it is a button. Hit Publish, pick App Store, and Blink builds the app in the cloud and uploads it straight to TestFlight. Boom, your app is on your actual phone through Apple's own beta app, and one submission in App Store Connect sends it to review.
What you need, honestly:
- An Apple Developer account, $99 a year. That is Apple's gate, not Blink's.
- Blink's Max plan, the tier that includes App Store publishing.
- A bundle ID like com.yourname.appname. Choose it carefully, it is permanent after your first build.
Before you submit, make it yours: your own name, your own icon, your own content and copy. Apple rejects lookalike copycats, and a version that visibly fixes the top complaints under its own brand is exactly what passes review. Rebuild the category, never the brand.
Why this beats building from scratch
Every failed app died guessing whether anyone would pay. You skipped the guessing. The original spent years and an ad budget proving people pay monthly for this exact product. Sensor Tower let you check that proof for free, and your version walks into the same charts with the complaints fixed and a better design. Same engine as the Arrfounder + Blink play, pointed at the App Store.

Frequently asked questions
A free Sensor Tower account shows the headline download and revenue estimates on app profiles, which is all this play needs. The deep dashboards are enterprise priced and you do not need them. Treat the numbers as directionally right rather than exact, they are estimates.
No. Blink builds the iOS app in the cloud and uploads it to TestFlight itself. You need an Apple Developer account, $99 a year, and Blink's Max plan for the App Store pipeline. No Mac, no Xcode, no terminal.
No. The prompt does the product thinking and Blink writes all the code, a native React Native app with the design system, notifications, and paywall included. When something looks wrong you describe the fix in plain English.
Competing in the same category is how the entire app economy works, features and ideas are not protected. Names, logos, code, and copied content are protected, which is why the prompt rebuilds everything from scratch and you launch it under your own brand. Apple also rejects lookalike copycats, so a genuinely better, clearly-yours version is both the legal play and the one that passes review.
Not until you want it to. The prompt ships the paywall mocked, it looks and behaves real but subscribing just unlocks premium on the device. When you are ready to charge, Blink sets up real in-app purchases during App Store distribution.
