Years of tracking gone. Nonexistent customer service

Completely unreliable app. After switching to a new phone I logged into my app only to find all my data gone. 5 years of tracking gone. I switch iphones yearly and have never had an issue before. I tried recovering as much as possible from memory and after a few months got it back on track only for the app to delete my data again. This time it will not let me log in to my account at all. Another year of tracking gone. Luckily i was smart and used another app as backup in case I had issues again. Emailing support is useless. I received an email back with an error message almost immediately. Do not trust your data with this app.

That was awesome until 3 years of data was deleted!

Here I am crying in my living room because I tried to create an account my iPhone did not warn me in time that all my local data was going to be deleted if there was any data on my new profile. Well I have never created an account before so no worries right? WRONG! Three years of information is GONE! I have been using this as information and back up to try and get my cycles fix with my doctors now I have nothing! NOTHING! This is a huge issue! I had no data going into my new “LOG on to FACEBOOK!” So it should have synced my local data well nope! Now I have nothing! No way of tracking my periods. I’m devastated! I have sent an email to support we will see what can be done!

Very helpful & highly recommended...

Not only do you have the typical calendar that predicts your fertile days and gives you a heads up as to around the time you’re next period will start, but you have the option of recording several symptoms as well as write notes. You can edit any entry from any date, and it saves entries for YEARS. Also, since I got this app several years ago I have yet to have issues with glitches.
