I installed the app from FDroid and it does in fact have on-device blocklists.

I did a search and found this comment, https://reddit.com/r/rethinkdns/comments/1f7ydjo/git_vs_fdroid_google_play_app_version/

After v055b, we hit numerous bugs (and unbelievably difficult ones) in our WireGuard integration. Released v055c and subsequent versions to fix the most annoying bugs among them.

We paused Play Store builds at v055e because each new version since has had its own glaringly annoying bugs (that were of course fixed in the subsequent versions). Why? Play Store brings in the most number of Rethink users (per our estimate), and we decided to halt publishing there until we can figure out how to stablize Rethink’s feature-set affected by WireGuard.

Pausing roll-out like this is a one-off.

Typically, you can expect all flavours (GitHub / Website / Play Store & F-Droid) to be at the same version.

If you’re feeling particularly adventurous: You can temporairly seamlessly update (without having to reinstall) to the GitHub / Website version if you’re currently using Rethink installed from the Play Store. And then later, when Play Store catches up, update from Play Store again.

I’m actually really glad u showed me this, MUCH more convenient than using adb!

That seems to only be available for Android.

No I did end up changing my studentaid email to an SL alias, though I might wanna change it back if it keeps having issues. The issue is that icloud bounced the email, and SimpleLogin itself gave me an email each time one got bounced, with to go to simplelogin.com and see the bounced email. This is the title for each one

An email sent to your alias redacted@simplelogin.com from donotreply@studentaid.gov was bounced by your mailbox redacted@icloud.com

Can this app work without a server, like just log my location on-device?

I want an app that can track it automatically, and without having to open it to do so, Google maps on iOS does so. You can allow apps to always access your location to do so.

No I used a different username on the site
