About
StoreTally tracks browser extensions and mobile apps across five stores (the Chrome Web Store, Microsoft Edge Add-ons, Firefox Add-ons, the Apple App Store (US) and Google Play) and keeps its own history of how their numbers change.
That makes it easy to discover new and fast-growing extensions and apps, follow one listing's users, ratings and rankings over time, and see how crowded a niche is before building for it.
Each store has browse pages with growth and ranking sorts, delisted listings, topic pages and a weekly roundup, plus new and breakout lists where the store publishes launch dates and permission pages for Chrome and Edge. Every listing has a page with its history and an embeddable badge.
StoreTally is free with no sign-up and no ads: a good way to find the fastest-growing extensions and apps without paying for an expensive app-analytics tool.
