A bit of background: I'm a solo dev with apps and games on multiple platforms. The pain was real — itch.io has basically no historical tracking, Steam analytics are scattered across Steamworks, and switching between Play Console, App Store Connect, itch.io and Steam every morning was killing my focus.
AppWatch scrapes and normalizes data from all four stores and shows everything in one place: downloads, ratings, reviews, crash rates. The itch.io integration was the hardest part since there's no official API. Steam integration is live and currently in testing.
Still early — MVP launched recently, looking for feedback from devs who publish on any of these platforms. Happy to answer anything about the technical side or the product decisions.
