Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.
First kit free with a verified email
Combine features and design from your favorite apps.
Your first Build Kit is free with a verified email.
Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Your apps' ranks, money and reviews in one place — and the money is Apple's own, not a guess. Start with rankings, which need no account at all. Your own App Store shows you one country; Apolu watches 175 of them, Top Free and Top Paid, on iPhone, iPad and Mac, around the clock. REAL REVENUE, NOT ESTIMATES Connect a key you create yourself and see what Apple actually reports: first-time downloads counted apart from updates and redownloads, in-app purchases and subscriptions counted as revenue rather than dropped. Apple publishes a day's report the next day, so today is filled in from your own server notifications — and the card says which part of the number that is. EVERY REVIEW IN ONE INBOX New reviews from all of your apps, lowest ratings first, translated when they arrive in a language you do not read, and answered without leaving the app. ALERTS WORTH READING A new country, a top-ten milestone, a jump of twenty places. Not a daily digest. On the Mac you choose which events reach you, app by app, and mute one that does not need to. EVERY STOREFRONT Where you chart worldwide and how deep in each category, from the overall list down to the one you actually care about. Chart appearances open in full, each country with the time it was last seen. ON EVERYTHING YOU OWN iPhone, iPad, Mac and Apple Watch, with widgets for the Home Screen, the Lock Screen, the desktop and Notification Centre. WORTH SHARING Turn a number one, a rating or a review into an image or a short video — three looks to choose from, in any of the languages the app speaks. Tracking your apps and the top 25 of any chart is free. PRO unlocks the full Top 100, every category, alerts, reviews and revenue. Revenue and reviews need an App Store Connect API key that you create yourself and can revoke whenever you like. Ranking data needs no account at all.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
Not assessed in a Build Kit yet.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
