I've been working on reverse-engineering Grindr and creating an open source client implementation for it since March.

When GrindrPlus closed, my project turned out to be its de-facto successor and immediatelly several thousands of people started following it. Now it has 70k+ downloads on Forgejo and the authorship is dedicated to public domain :)

• MIT licensed, no ads, no analytics, no trackers, no diagnostics, no statistics, no telemetry, only opt-in updates checking
• Signed releases, reproducible builds on all four platforms, full transparency
• And it's now in Google Play (for the time being) and being reviewed for F-Droid!

Already applied for Apple developer enrollment and going to publish this to EU alt stores as well as in the TestFlight. Then a classic unsigned ipa and also going to attempt Apple AppStore just for completeness.

You need an existing Grindr account. Downloads: https://opengrind.org/download
