Ratings and Reviews

Great app


I would give it 5 stars if it used Touch ID

Access to speaker?


Added on May 14, 2016:
I know this app hasn't been updated for a year now (all I remember is that the last update was in 2015) but I think the TouchID should be enabled for in-app password. Also, it's great that I can turn off items in settings like "temperature" for example, but even when I do, temperature is the first thing that pops up when I go in to the graph. I use this app to track my weight, and saw in many reviews that many others do, so I just wish when I turn off temperature, I can make it go away in the graph as well. But other than that, great app - simple, intuitive and as accurate as an app can be.

Previous review:
Okay I was using the free version for several years, and I finally got sick of the ads that made the free version literally unusable- so I bought this paid version. For some reason when I have music on speaker and open this app, the music stops. Maybe this app accesses the speaker for no reason? Annoying! Other than that, it's simple it's accurate - what else do you need in a period tracker?

Best Cycle Tracker!!! 😍


I have downloaded numerous menstrual cycle apps. I have tried them out and deleted them when they aren't up to par. This one is the best by far (and of course the only app I kept). You can alter and track almost anything you want. It is very user friendly. I love it so much I paid a couple bucks for the ad free version and it was totally worth it!

Also, I noticed another review about the Backup Dropbox not working. I haven't tried it, but I have done the Backup via My Days and it works easily. You just type in your email address, click Upload. Then you open your new My Days app. Go to the MyDays backup, type in your email address and Individual Backup ID (which can be copied from your email), then click Restore. That's it! All your old data will reappear!!! 😄
