The problem is that stuff like privacy and open source don't attract the vast sums of venture capital that ad-selling businesses do. Sure, an average dev could probably build a working app like that - but could you ship the same quality as someone who can afford to hire an entire UX team?
imo, the real problem is that you need to consistently ship. It you made a one-off app then it's going to get de-listed for not being updated despite not needing an update.
Seems too nerdy for the market at large - the correlation etc. features might well be as good as or better than what the likes of Flo provide, but people will have a harder time understanding that than simply 'your next date is expected to be x', 'your cycle is typically x days', etc.
