Great App still (2nd review)

This app is great, it’s simple and I really like that. I don’t need all the unnecessary settings that are on all the other apps. I’ve had this app for almost a year now and this would be the first time in my life that I’ve ever kept a log of my monthly period and I love it. The reminder option is one of my favorites and being able to look ahead in case I have an event or something coming up. I’m able to prepare ahead and I love it. Please don’t change anything on the format itself but if we could choose other colors for the theme or being able opt out of everything besides the actual period tracking would be nice. I’m not having anymore kids so i don’t need to know when I’m most fertile. But still a great app!
This is my 2nd review on this app. I still feel the same, it keeps great logs. You’ve added different themes... thank you! Still would like to turn off the pregnancy all together but it doesn’t bother me. One suggestion I want to make and it’s because I recently have had some issues pertaining to my period. Is there anyway you can make it to where I can send my OBGYN my information so he can see how long my periods have been, the flow, symptoms, weight, temp and most importantly my notes and medication. Somehow where I can send them all the information and he can get it all in a graph format or timeline. That would be awesome. I’ve been using the free app for a year and a half now and it’s still great . Thank you!

Helped me get pregnant first try.

I have been using this period tracker for 10 years. It has always predicted my period accurately. I never thought I could like it more. But when it was time for my husband and I to start trying for a baby we bought ovulation strips, and used this app. On the day of my peak ovulation (according to this app) my ovulation strip showed very low levels (meaning less chance of ovulation). I decided to listen to the app and not the strips and I’m so glad I did. I found out I was pregnant two days after I was supposed to get my next period. I fell in love with this app even more! But wait! There’s more! After I found out I was pregnant I switched the app to pregnancy mode. And it conveniently tracked the weeks of my pregnancy. And since calculating a due date is based on the last day of last period (which is also how you calculate your ovulation day) the app correctly calculated my due date (which was later confirmed by my OB).

If you are still reading this, here is my only complaint if I had to say one. Since there’s a pregnancy mode, there should be a postpartum one too. I didn’t get my first actual period after giving birth till 5 months later and the app kept asking if I was pregnant because I wasn’t logging a period after said I had delivered.

Great app with a single exception

My single exception is quite enough to render the stars for my case. I downloaded all the period apps. All of them. And I filled out my menstrual info as well as moods and symptoms in between in every single one of them for several months to test out which one was best for me. It was exhausting, took up a lot of time, mental energy, and ambition. It was also annoying. But it came down to this app. As long as you keep up with it anyway. It has lots of useful if not neat graphs and charts that puts all your info in a visual prediction for you. My only disappointment is that in all the apps including this one, there is no option to choose that you are infertile. There is no collection of data anywhere that helps a lady out if she has a period but can concieve. It would be so nice if we didnt have to do a bunch more work than other women. Or at the least a toggle button to turn off anything related to becoming with child so that its not in the way for those of us that dont need it and have to literally work around it to figure stuff out. With that in mind this is the best menstruation/period tracker app for me. I also use it along side an app cal hormone horoscope. Its like a period prediction app for whats going on mentally during your stages of the month which is helpful for helping tomorrow have its best change against raging hormones. Together they are worth the effort for all the heads up, collected info, and recollection of past logs.
