I use Android, my wife - iOS. So many things that on F-Droid are simply unavailable to her (yes, I tried to convince her to go to our side). So I searched for living projects with self-hosting idea, did not find one and decided to create one. I have a CS background, though my professional work today is mostly in finance as a senior analyst where I write code to automate and optimize workflows. Ovumcy started as a personal project exploring a self-hosted approach to cycle tracking.
