Tip for #android users:

If you search for simple utility apps on #google's play store it will almost always give you a bunch of options that contain ads or ask for unnecessary permissions.

F-Droid is an alternative app store for android devices which exclusively lists apps published under the AGPL (a #copyleft / free-software / open-source license). It's possible to install F-Droid on a normal Android OS via its APK, but that can be intimidating.

Most of the apps on F-Droid are *also* available on the play store. So, even if you aren't ready to fully switch out of Google's ecosystem, you can still use F-Droid's search as a better way to find options that are (in my experience) free of ads and surveillance.

Each app features a page which links to their source code, which usually has a README file, which usually points to their page on the play store.
