Great app for ovulation, period and pregnancy attempts!

Really love this app! I have used it religiously for over 5 years when attempting to get pregnant, having failure in getting pregnant (showing my doctor what I have tried to obtain a fertility specialist referral ) plus tracking my cycles while going through miscarriage, fertility treatments and attempts at conception naturally. Not to mention this app transitioned me through a pregnancy, return of my cycle and trying again for baby number 2. I had no defects, problems or use with this app. Completely reliable!! I am still using it and rely upon it completely for tracking periods, ovulation and planning. Really easy to use and modify for your own use. This app tracks menstruation cycles, optimum ovulation, moods, weight, basal temp, "love dates" and any meta data you desire to track when things happened and when. I have used it to back-search data for when I took shots or took specific tests. I found it invaluable in when going back to the doctor for information they needed about outside specialists or dates on when things happened. Highly recommended!

Happy with this app for 4 years...

I've been using this app since 2010 and I truly love it for multiple reasons. I use it frequently to track the symptoms and moods of my cycle, and it has helped me tremendously. I've had hormonal imbalance due to a thyroid issue for years and the use of this app has not only educated me on the challenges during my cycle, but also helped my doctor and I to determine a course of action to correct the problem. I also love that I can check the date of my most recent period and share this information with my doctor. Very helpful tool!

Yes, finally!!...

I have been using this app for various reasons over the past 3 or so years. I love it and had literally only 1 complaint about it. It did a strange thing where it doubled the amount of apostrophes in each word every time you edited a daily note. I've had to deal with that for years! I finally decided to write an email to the support staff and ask about correcting this. I don't know if my email helped change this, but very glad they figured it out. Definite 5+ stars from me! Does and tracks everything you want!
