@TeomaHK Hi there, apologies. This has been reported before: https://github.com/celzero/rethink-app/issues/2219 And we've since made the fix & made the feature (causing the crash) optional in the pre-release v055u (but v055u has other bugs and isn't on F-Droid).

v055v is imminent. UI bits (for "RPN", which is paid) undergoing a bit of a refresh, & that's taking time.

We've turned on "Alpha" builds which auto-publish 27th of every month (the March build will contain fixes to issue you're seeing): https://github.com/celzero/rethink-app/actions/workflows/nightly.yml

@hiker @bsm Our GitHub pre-releases page mentions presence of Crashlytics (which is disabled by default) in GitHub/Website versions: https://github.com/celzero/rethink-app/releases/tag/v0.5.5u

The F-Droid versions will not contain Crashlytics.

For technical rundown, please read through commits, comments, and linked issues: https://github.com/celzero/rethink-app/issues/1455

@flxtr v055n is the last stable version.

And v055v should be available on F-Droid. There may be problems we don't forsee right now, but the expectation is that it'll be released on F-Droid, too (unlike v055u which had build issues specific to the F-Droid flavour on our end).

@bsm Crashlytics isn't necessarily a "trackerware".

For a firewall app like Android, stability is paramount. We tried & failed building a cost effective, scalable crash reporter ourselves.

1. Crashlytics isn't included in F-Droid builds, and it won't ever be.

2. Crashlytics is off by default (an end-user may opt-in from Configure -> Settings -> Stability program).

3. With v055v, an end-user will be able to create firewall rules (allow/block IP/Domain) to Rethink's own connections.

@flxtr v055t has a severe bug that corrupts the "app details" database. We've since fixed it for v055u, but that version has other problems.

v055v is the upcoming version, which is ready for a release since Jan 3rd week, but both the lead developers are on leave until 18 Feb, which is why v055v has been delayed for the time it has.
