I'm looking for an automatic Android app updater. I'm manually installing apps that I want using a web browser, and I do not have an app store (Google Play, Mobogenie, Aptoide, etc.) installed. I want to keep them as up to date as possible without the hassle of having a full-blown store that offers non-app downloads and porn (even "light porn") right on my device.
If anyone knows a good app-updating app, please leave an answer. Even better, if anyone knows of a clean, unobtrusive app store I can use, show me where I can find that.
If details are required, I am running Android "Lollipop" 5.1.1 on a Samsung Galaxy S5.
