Mostly Good


I like that I’m able to keep track of my periods and view them on calendars. It helps knowing when my period’s coming so I can plan trips around it. I like the daily logs, but after you do a log, there are notifications trying to pep you up and give you scientific information and they never have anything to do with what you logged. i.e. I might log that I’m sad because of work and the notification will say I’m happy because of my relationship. I tried notifying the developer of this issue using the in-app feature, but I can’t report it because I don’t pay for any of the gems. Other than the developer not being open to feedback, the app serves its purpose for tracking period systems and cycles.

Edit: The developer added a link through the app store to provide feedback which was a step in the right direction until I completed the form and wasn’t able to submit it to them. There are gems that repeat information from week to week, some of the quizzes don’t provide factual information, and Bedsider asks questions for you to ponder then doesn’t provide you with the answer. Just keep the app for tracking periods because the rest of the app is useless and you still can’t submit feedback.

Developer Response

Hi there! I assure you we are very open to feedback and we appreciate you taking the time to reach out! As far as the logging issue goes, to get the correct symptoms and causes, you'll need to log them in the same order. For example if you log happy and stressed, then when you go to log the causation, log the cause of your happiness first and stress second. I understand that this could be confusing, so I'll make sure my team is aware of this feature. If you have any further feedback on how we can give you a five star experience, don't hesitate to email us at!

Does the job plus lots of extras


I like this app because it does everything you could possibly want a period app to do. It allows you to track your period and keep a daily log of symptoms, exercise, sex life, and more. Then eve will suggest mini articles based on your log. Your homepage displays the important points in your cycle (days from fertile window start/end, days from period start/end) and eve will notify you a couple of days ahead of time. I've had this app for about 3 years now and I can't remember it being more then a day or two off unless there was some other factor-- stress, for example...and I sometimes forget to log it and have to sort of make it up so I'd say she does a pretty good job! Eve also has a very comprehensive community forum where you can participate in conversations on various topics: sex, fitness, love, family, birth control, periods, plus tons of others. I've had at least 2-3 other period tracking apps in the past, but since getting this one I haven't felt the need to try anything else.



Pretty good at keeping track of my period. Sometimes it's a little off, but that's just my body. My period's can be so irregular, so it won't be right every time. I like being informed of what's going on with my body during different times throughout my cycle. I like all the quizzes and facts, etc. as well. It makes the app fun. I like the community aspect of it, knowing that there are a lot of women out there who go through the same stuff I do, so I know I'm not going crazy, haha. The only thing I don't get, and I guess it goes back to the slight inaccuracy of the app, when I have logged a period the last two times, about a day or two after my period ended and I would do my log, it would say what cycle day it was, and then would say my chance of pregnancy was 7% and would continue going up. Currently my supposed chance of pregnancy is at 33%. Not sure how that's possible considering my last period was not even two weeks ago, but oh well. That's the only weird thing about the app. Other than that, it's great 😄
