![[Android][App] Obtainium. Get Android App Updates Directly From the Source.](https://raw.githubusercontent.com/ImranR98/Obtainium/main/assets/graphics/icon.png){kind=link}
Awesome app. It is somehow not listed on android-foss list so maybe someone didn’t know about it.
Obtainium allows you to install and update Open-Source Apps directly from their releases pages, and receive notifications when new releases are made available.

Sure, at one point you have to trust something or someone unless you want to read all source code for all apps you use. Thankfully there are quite a few people out there who do basically that and report issues they find, but ultimately, reading all source code and compiling everything by yourself would be the only way to be safe.
