About

What Tech Dev Notes tracks.

Tech Dev Notes is an independent project that monitors how the most interesting AI and developer apps perform across the Apple App Store and Google Play — so you can see what shipped, what is climbing, and how leading apps are built, all in one place.

What we cover

Live store charts, country-by-country rankings, weekly movers, a tracked-app leaderboard, full version history, real-device screenshots, and detected tech stacks.

How the data works

We collect publicly available data from the App Store and Google Play — chart positions, store listings, ratings, release notes, and version metadata — and refresh it regularly. Figures are snapshots of public store data and may lag the stores by a short window.

Independence

Tech Dev Notes is not affiliated with, endorsed by, or sponsored by Apple, Google, or any of the app developers tracked here. All product names and trademarks belong to their respective owners.
