Since the two most popular period trackers Flo and Clue send data to the cloud, many are looking for alternatives.
Both apps combined have over 55 million users in the US, this could be an enormous boost for F-Droid, especially since women are underrepresented in this project.
I think a lot of users care more about looks than functionality, and Drip is probably the best looking one of the bunch, so I personally think the best thing that could happen is for Drip’s F-Droid support to get fixed.
