As answered by people managing Eloquent JavaScript and AppRankSpy.
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.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
