First of all this app is free!
Second of all, this app has more useful features than just tracking your period, it has a mood tracker, a place where you can write a dairy, sex life and etc... not only that but it can also help you have a healthier lifestyle too. It’ll ask you questions about your height, weight, waist measurement and so forth to help get you a better idea of your body fat percentage and to let you know if your healthy. The app has many videos on how to take care of your body and what to do if your on your period like if you have acne during your period for example. It’ll help you know what you should do, there’s even excerises you can do, helps track the amount of water you drink, amount of sleep and so forth. This app lets you know where you should be at to have a healthier life, like how many hours you should sleep each day, how much water you should drink, the average amount of minutes you need to workout a day and so forth. This app has many perks and features to help track your period and lifestyle and it’s all for free so there’s no need to pay extra money on other apps for this kind of info. Oh!

My only suggestion so far…

Only thing I’ve found I would want changed (after a few weeks of non period tracking use and the start of first one tracked) is being able to select multiple levels of flow. Like on days when it starts light and then gets heavier, being able to select both/or all 4 and then select like morning, midday, afternoon, night or something along that line would be nice. So that way it’s logged, at the moment I just write it in notes, I just think that would add to the tracker and Helping me/others realize if I’m just spotting heavily or starting my period off very lightly.

Otherwise I love this app and the fact you get so much without having to pay is amazing and I looked through a few apps cause as someone who doesn’t have much extra money right now it helps to be able to keep track of something that I can’t avoid and I know you could do it on paper but I mean with it being on your phone it’s so much more accessible and with you 24/7, if your like me, which means you can’t forget it.

Oh the ads

—- Update after dev response —-
Mainly the ads I was discussing are the ones that pop up (take up the whole screen) and are in a different language so I can’t exit out of them (no exit button) and it shows two option buttons (again in another language). Finally I took a chance and clicked a button and it exited out. My fear here is what site the other button would point to so I checked and it was fine. I’d say I prefer the ads that are in between sections of the calendar instead of the ones that pop up but I am guessing those bring more revenue. In any case, like the dev rightly said, I can just pay if I don’t want ads!

While I love the calendar, options to add notes, reminders about my period, the ads are just getting to be too much. I cannot exit out of them most times. I want to go in and check when I had my period or if I am ovulating and it’s a 5 minute ordeal unless I give up. I get the need for ads I do, and I have had this app for years, but the way they do ads has changed and it’s so disruptive and really makes the app unusable. Will seriously be considering going to back to just writing stuff down myself or another app.

Hi, thank you for your long-term support and we really value your comment. If it's convenient, could you please send us the ad link or screenshots to help us optimize it? You can contact us at

We understand ads may affect your experience, we are still working on it but so far it is the best way that users can stay free at a minimal cost while keeping our team running.

We won't give up trying. Besides, according to some users' needs, we have also introduced permanent ad removal, so users can have a completely ad-free version at a small cost.

We are making efforts to optimize our app and if you have any questions or suggestions, feel free to contact us. Thanks again for understanding we have ads.
