For the past year or so, I have been trying to find open-source alternatives to the apps that I use on daily basis. Especially trying to replace the ones that need gazillions of permission even before installing, nowadays even a photo editor needs a microphone and GPS access (;¬_¬) In fact, apps know too much about you, for instance, most of the keyboard apps that you use commonly are loaded with spyware to track words that you type.
