It’s nice to have a record but the app is glitchy. The math isn’t always correct; for example, I was told the average length of my cycle and it was incorrect. It’s pretty simple math and it was off my 50%. I also find it extremely annoying that I can’t scroll smoothly through the months to get an overall look at what I’ve recorded. The screen constantly refreshes and I end up “jumping” to random months, instead of a smooth scroll through the calendar.
