Help shape a personalized and private fertility-data app

I'm building an app that puts your fertility data from different apps and devices (Premom, Inito, Fertility Friend, smartwatches, lab results and more) on one timeline, and lets you ask questions about it. Everything runs on your phone: your health data never goes to me or to a cloud AI.

This short survey (about 3 minutes) helps me decide which apps to support first. It doesn't ask for any health readings, and every question is optional. My motto is: Your data, your choice.
