AppMaple tracks software everywhere it's sold: browser extensions, iPhone and Android apps, and Windows and Mac software. Users, ratings, update history, who built it, and how it makes money, with weekly snapshots that show what's growing and what's been left to rot.
We're opening AppMaple to a small group first.
Each store shows you one listing at a time. AppMaple lets you sort and filter all of them, across every platform.
From browser extensions, the first platform in the data. Pulled from public store listings, with no estimates.
Extensions with over a million users that haven't shipped an update in two years. Google Classroom, with 17 million Chrome users, was last updated in May 2017.
LastPass has 8 million Chrome users and a 1.8-star rating from 28,500 reviews. Three password managers with 7 million or more users all rate under 3 stars.
Tampermonkey has 13,902,559 installs on Edge, more than the 12 million Chrome shows. Edge reports exact counts. Chrome rounds, so we track both and match them up.
Data as of November 15, 2026, from the Chrome Web Store and Microsoft Edge Add-ons.
Public store listings (Chrome Web Store, Edge Add-ons, Apple App Store, Google Play and Microsoft Store) and open software catalogs such as Homebrew and winget, collected at a polite rate and within each source's published rules. Business models come from each developer's own public website.
Chrome and Edge extensions, Apple App Store apps (iPhone, iPad and Mac) and Mac software from Homebrew are in the data now. Google Play and Windows are being added next, and waitlist members will see them first.
Every platform reports usage differently, so we label each number with its source. Edge and Homebrew publish exact counts. Chrome and Google Play show rounded tiers (10,000,000+), and we show exactly what they show. Apple and the Microsoft Store don't publish downloads at all, so for those we track rating volume and clearly mark anything that's an estimate.
Two groups so far. People who build apps and extensions, looking for categories where demand is high and the incumbents are weak. And investors and acquirers who want to screen the whole software market for acquisition targets, not just the ones already for sale.
That's the plan. Tell us how you'd want to use the data in the sign-up form; it shapes what we build first.
Pricing isn't set yet. People on the waitlist hear first.
Early access is limited. Add your email and tell us what you'd look up first.
