I’m an indie builder working on app-related data for a long time. Appark is a free tool that helps you quickly explore app market signals like downloads, revenue estimates, rankings, keywords, and competitor trends across App Store and Google Play.

The original goal was simple: make early-stage market research easier before building or scaling an app — without relying on expensive enterprise tools. It’s still evolving, and I’d really appreciate feedback from other developers and founders who care about data-driven decisions.
