There are a lot of apps out there in the world but if you want or need simple ones, that can be a bit hard to find. Most apps ask for a host of permissions and come embedded with some really obnoxious ads. Simple Mobile Tools is a suite of Android apps for those who just want things to work.
There’s no problem with ads, in theory. In practice, they’re annoying and inconvenient. Placement, popups, etc. Sometimes, it’ just too much. Also some apps just come loaded with features that we don’t need. That’s what makes these apps so great, they’re basic.
These tools have a simple calendar, gallery and even a draw pad for doodles. These are open source solutions for everyday problems. Because they are “barebones” apps, they don’t eat up a great deal of resources on your device. You can check out these easy to use and functional apps in the Play store or on F-Droid.
