Love everything about this app! I love the tracking options, the metrics, the data reports, and the projections! Super helpful and amazing. Also love the privacy policies, especially with everything going on in the US right now attacking womens' privacy in healthcare data. My only issue is the calendar sometimes resets back to 2012, so I have to navigate a little wonky. But in an app that does THIS much functionality? That is spectacular!

It's okay, I like that it doesn't sell my info, but I have a suggestion: 1) please have it so that when you begin tracking your period, that it tracks automatically for the average 7 days (allowing you to shorten or lengthen as necessary) without having to manually do it every day. Flo does their tracking automatically. And I don't want to put how heavy the flow is but the app forces me to do this. I just want to track that it happened, not the amount (Flo also does this well). Pls email me.

The complete removal of the fertile window tracking is a big setback. Yes, we all use this app for different things, but removing this feature entirely takes away the option that many people use as a guide (I use it to help get a feel for my hormone levels, for example). It does the exact thing that it says it is trying to prevent (forcing people to use the app/tracking features a certain way) by removing it without the option to turn it back on.
