Simple Mobile Tools was a collection of basic, free, open-source apps for Android devices, including a file manager, calendar, and photo gallery. The apps were popular alternatives to paid apps and services, but the developer sold out the app suite to ZipApps recently, which then proceeded to ruin the apps with subscriptions and ads. The Fossify project has picked up where Simple Mobile Tools left off, so you can keep using the excellent app suite on your phone or tablet.
