As answered by people managing AppRankSpy and Learn JavaScript.
AppRankSpy's answer
Sensor Tower and data.ai cost thousands of dollars per year. AppRankSpy offers the most useful data (new launches, rankings, SDKs, ad creatives) with a free plan and paid plans from $20/month.
AppRankSpy's answer
Indie app developers, mobile game studios, ASO specialists, user acquisition marketers and investors looking for new app trends.
AppRankSpy's answer
It combines daily new-app discovery for both the App Store and Google Play with rankings, SDK detection, ad creatives and an app status checker in one simple tool, at a fraction of the price of enterprise platforms.
AppRankSpy's answer
I wanted to see every new app launched each day and understand how apps grow, but the existing tools were far too expensive for indie developers. So I built AppRankSpy to make app market data affordable for everyone.
AppRankSpy's answer
Next.js, React, TypeScript, PostgreSQL, Prisma and Python data pipelines.
