Very good, I've had the app for a few weeks now about a month or two and still no complications. It tracks my period, and gives me some basic tips/informacion to aid and help me understand my body better. Free articles with information by MD professionals, but you do have to pay for the premium version that does give you access to insights. There are also chats to discuss certain topic and just personal preferences with others. The community is lovely. It's definitely helps make things easier.

Won't sync to Google Fit I would like to see graphs and reports for the parameters as well. It's kind of annoying having to go to every day individually to see when I tend to get acne flares, when I had s(e)x, when I get cranky, moody, cramps, etc. It shouldn't be difficult to add as you already have the information. You just have to add so it gathers the info into graphs. I just don't see the point of including the parameters when it's not easy to check for patterns.

i love this app. its relatively simple to use, and is surprisingly accurate. i find that its almost never off, and if it is, it's only by a day or two. also, if you change devices, say, a new phone, as long as you log in, it'll save your past cycles for you. i like knowing when i can expect my period. the only complaint is premium. i find that there's not a lot of things one can do without premium, so thats kind if a let down. but overall, i find this app to be very useful and i recommend it.
