What is apptomy?

apptomy is an App Store and Google Play chart analyzer for people who build apps.

It collects the public App Store charts of 175 countries and the Google Play charts of 30 countries every day and turns them into app ideas: which apps are climbing, which popular apps have been abandoned, which hits have not reached another country yet, and roughly how much a grossing app earns. For any app it can also read the real user complaints, write an Anatomy report with the themes and a prompt for a better one, and let you follow apps on a watchlist.

How we calculate it

Independent of Apple and Google. Data comes from their public chart feeds and app lookups.

Pro

See why users complain. Get the prompt to build the fix.

For any app, apptomy reads its real low-rated reviews with AI, groups the complaints into themes with word-for-word quotes, and writes a ready prompt for your AI coding tool.

  • Complaints, with proofThemes ranked by how many reviewers mention them. Every quote is checked against the original review.
  • A Build Kit you can pasteWhat to fix, how to be different and what not to copy, written for the tool you build with.

Every free account gets 1 trial report. Pro creates up to 30 a month.

How we estimate

Numbers that admit what they don't know

Nobody can measure another app's revenue from outside. We show ranges, say how sure we are, and keep every input visible.

Didn't find your answer?

Write to us and we'll get back to you.

Where does the data come from?

Public App Store charts and app details for 175 countries, plus public Google Play charts for 30 countries, collected daily. We are not affiliated with Apple or Google.

How accurate is the revenue?

It is a model, not a measurement. We show a range and a confidence label, and say "No estimate" when the data is too thin.

Is it okay to build on what I find here?

Yes, as your own product. Reports show what users complain about so you can build something different and better. The prompt asks for a different product and forbids reusing a name, icon, screens or text. Apple's rules don't allow lookalikes either.

Who can create reports?

Every free account gets 1 trial report. Pro members create up to 30 a month. Anyone with a free account can read the sample reports.

What do I see without an account, with a free account and with Pro?

Without an account: Charts first 10 rows · Rising 3 · Zombies 3 · Small & simple 3 · Gaps 1, with 7 days of rank history. Free account: Charts 25 rows · Rising 5 · Zombies 10 · Small & simple 5 · Gaps 3, plus 1 trial Anatomy report. Pro: full lists, 90-day rank history and 30 Anatomy reports a month.

Is Google Play covered?

Yes. We track Google Play charts in 30 countries: rank, install range and rating. The two stores stay on separate pages and are never mixed. There is no revenue estimate for Android, only install ranges. Rising, Zombies and Gaps open on Android as enough history builds up.

How fresh is it?

Charts refresh once a day. Each list shows its date.

What is apptomy?

apptomy is a web tool that reads the daily App Store charts of 175 countries and Google Play charts of 30 countries and shows rising apps, abandoned popular apps, cross-country gaps, small and simple apps, estimated revenue ranges and Anatomy reports on user complaints. You can also follow apps on a watchlist.

How is the revenue estimated?

Apple does not publish revenue. We convert an app's Top Grossing rank into a monthly gross revenue range with a calibrated curve, scaled by country and category, and we label the confidence. Details are on the methodology page.

What is the small and simple score?

A 0-100 score that favors apps a small team could build: a developer with few charting apps, a modest number of ratings, a small download size, a paid or freemium model and steady demand across charts.
