You can, and you should — it is the same source. But the store only ever gives you a rounded band — 1,000,000,000+ for ChatGPT today, and it does not keep yesterday: today's figure overwrites it, and nobody can go back and look.
What we do is take the exact figure behind that band, once a day, and keep every one of them. So the store answers roughly how many. We answer exactly how many, and how it is changing.
It sits in the listing's own page data, behind the band, and that is the number we copy and keep. Today ChatGPT's listing shows 1,000,000,000+; the counter behind it reads 1,567,613,533.
At a glance you can check that our figure falls inside Play's band. If you want to go further, the exact field is in the listing's page source. If the two ever disagree, we are wrong and we want to hear about it.
Estimate vendors model what they cannot see and sell you the model. There is nothing to check against, so the methodology page has to do the convincing.
We do not model anything. We copy a figure Google itself publishes in the listing, write down the day we took it, and never throw one away.
It won't, and that is expected. Play Console reports your app with several different install metrics — install events, installs on active devices, unique users who ever installed — and the counter Google prints on the public listing is not defined the same way as any of them. They are different measurements of different things.
We copy the public one, exactly as Google publishes it, and we do not convert it to anything. Google publishes no mapping between the two, so nobody can honestly reconcile them — and a site that offered you a conversion would be modelling, which is the one thing we do not do.
So: the figure here is the right one for comparing apps to each other and for watching one app move over time, because every app on the site is measured the same way. For your own app's real install accounting, your Console is the source, and always will be.
Every app page shows the day it was last updated. Most apps update daily; follow one and it updates every day from then on — that is what following does, and it is free.
Because not every app is updated every day, and we would rather show you the hole than fill it. A missing day is drawn as a break and named; the dashed segment across it spans two real figures rather than measuring one day. Nothing is invented to smooth it over. Follow the app and the gaps stop.
No, and neither can anyone else honestly — Google publishes download counts worldwide only. What it does publish per country is chart position, and we record that daily for every market we scan. So on an app page the downloads are global and the ranks are per-country; they are two different measurements sitting next to each other.
Not covered, and probably never. Apple does not publish download counts, so there is no counter to copy — only estimates, which is the thing we do not do.
Only as far as our own record. Collection began on Aug 4, 2026, so nothing here predates that, and an app added later starts from its first reading. Each app page says how many readings it keeps. Google keeps no history of the counter, so no one can reconstruct the part before we started — including us.
Not to read. Every app page, every exact counter, every chart position is open — that is 389,697 apps, with no sign-up and no card.
An account exists for one thing: following. Following puts an app in tonight's reading queue and opens your own window on it, which is a promise we can only keep if we know who you are.
Yes, through the API, which is part of Pro: every reading of any app as JSON, a watch list, a changes feed, 500 calls a day, key from your plan page. Docs at /docs. Every app page also has a machine-readable version at /app/<slug>.md, and the site publishes llms.txt.
Write to [email protected] with the package id and the date. Every reading is kept, so it can be checked against what we actually recorded that morning — and if we are wrong, the correction is one person away.
