Valentin's PowerTools #006 - Yes XOR No?
APK
This app is for situations where you just cannot decide on rational grounds because of missing data or because the decision tree is so complex, a human could just flip a coin, because the computation of all outcomes would not be possible in the remaining life time. If you want to minimize the time you would normally lose in option paralysis, just press the big red button. The answer is a decisive and strict YES XOR NO. And there is also a delay to hinder you from fooling yourself and coming back to biased circles of fruitless thinking. But this is just what I think. Let me know what you think in the comments. ;) Everything is calculated locally, nothing is saved. Your data are yours. Nobody will ever learn about your specific love for wearing mismatched socks. How does it work Ask yourself a Yes/No question in your head You click the big red button Your answer will appear on the screen To prevent cheating, you can't go back for 5s.

Vanced microG
APK
microG GmsCore is a FLOSS (Free/Libre Open Source Software) framework to allow applications designed for Google Play Services to run on systems, where Play Services is not available.This fork tweaks MicroG to be usable by applications that require Google authentication such as Vanced.Notable changes:No longer a system appPackage name changed from com.google.android.gms to com.mgoogle.android.gms to support installation alongside the official MicroGRemoved unnecessary featuresRemoved all permissions, as none are required for Google authenticationNote: microG (and so this fork of it) provides FOSS replacements for proprietary libraries in order to make apps which depend on such work. So a scanner will find the names used by those original, proprietary libraries as if they were there (which is how the apps needing them find them). Still the app won't be marked with the corresponding AntiFeatures, as those would apply to the original libraries only. NonFreeNet is still applied for Google authentication. Tracking is not, as Firebase Analytics here is just a stub (an „empty shell“ without functionality).
