Great app, I've been using this app for more than 6 years now, its always been super accurate, and the little animal companion thing they've added is quite cute. I also love that for just under $5 I can remove ads forever!
Love love this app been using it for over 3yrs now and I have had no problems. Still no problem the best app of its kind
The tracking of the cycle is spot on. It also shows when you are the most likely, and least likely to conceive. Wondering if you're PMSing? It shows that on the calendar too.
Have been using this one for so long, accurate tracking and even helped me with calculation during pcos and the animations are the CUTEST 💖
The only tracker I've ever used, since my first smartphone When I tried to get pregnant, this app predicted my ovulation better than all the other fancy ones
