I like the app so far. I have been using the app since May. The only 3 things I would change would be to allow users to add moods that are not already preloaded, add symotoms that are not already preloaded, and allow users to sync Samsung Galaxy watches to the app to track steps and other things. Moods like tired, forgetful, lethargic, options for increased or decreased appetite, etc aren't in the app.

When I first downloaded to get pregnant( with my son) it was great! Now a days you have to sign up for premium ( which costs money) to do anything. It's super annoying because i was tracking to get pregnant again and I'd imput data ( like if I was having cravings etc) and it would change my ovulation date for no reason which made it so confusing to know when I was ovulating. Overall I wouldn't reccomend, I'm sure there are better truly free apps out there. This one sucks now!

I have tracked my cycle for years and wanted to try an app in hopes of understanding it more as I am entering perimenopause. This app is geared towards younger women, not older. There is no way for me to track hot flashes, there is hardly anything at all for monitoring irregular cycles, and hardly any articles on perimemopause or menopause. If one is 40+, this app offers very little. The health assistant also is of little use unless you pay for it, which why pay if they have nothing for 40+?
