### 5/5 — Great app!

*2024-07-09, version 9.9*

I have been using this app for over 15 years now and it’s great. I like it’s simplicity and the fact that it’s user friendly. I’ve had 2 children in the meantime and it helped me keep an eye on my fertile days as well as my cycle. Stats are great and always useful if you need to remember the last day of your period ☺️

### 5/5 — Perfect practical easy to use

*2024-01-15, version 9.9*

Straightforward app with everything I need. Simple to use and very well designed. I’ve been using it for 12 years at least. No bugs no crazy updates where your data is changed around. You can add symptoms feelings weight etc if needed. Tracks days since last cycle, body feels and emotional ones. Shows info in charts if you want or on calendar. Displays information clearly. No clicking through weird complicated pages. I can go back through my data easily. Shows trends by year/month etc with few taps. I am never confused while using this app. It’s easy simple complex brilliant 
I love the look too. No pink!!! Easy to follow use and best app out there. 
I used their other product fertility friend for getting pregnant, which was hard bc of endometriosis issues plus. It was simple and brilliant

### 1/5 — Over 14 years of records gone in a flash

*2023-10-15, version 9.9*

Very disappointed to see all my data disappear. Given I’ve used your app for over 14 years without changing a single thing in all that time of how I used the app then to suddenly lose everything is a real kick in the guts. Not reliable at all if I can’t see my stats. I guess at the end of the day pen and paper and following the Billing’s method will always trump technology.

### 5/5 — Отличный календарь

*2023-02-28, version 9.8*

Пользуюсь уже много лет, отлично предсказывает дату

### 3/5 — Graph cannot be sent anymore

*2023-01-01, version 9.6*

I just updated the app around 26 Dec 22 and realized that I can no longer send the graph in the original format  to my email for record- there are errors in the format and it is in an unreadable format. Please rectify

### 5/5 — Best period app hands down.

*2021-11-10, version 9.6*

I’ve been using this app for at least 8/9 years and I refuse to use others. Easy to use and accurate each month. Please keep it around!

### 5/5 — Amazing

*2021-10-03, version 9.6*

I’ve had this app for a few years now because my periods would show up whenever they felt like it. At first the app would give me the standard 28-day cycle, but it started learning my body. I’ve been inputting every cycle and it’s now properly guessing when my next cycle will begin and it’s been nearly correct every time! Kudos to the developers ❤️❤️
