HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (799 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ Now it lacks any visuals and it lags.
★★★★★ I get on the app this month to do my login and the screen hasn't been loading for about 4 days so I restarted the app.

Wrong or poor results9%

21 of the 1 and 2 star reviews.

★★★★★ Useless I don't want yo spend my time dealing with an app all I want is to log my periods while going through perimenopause but apparently a literal period tracking app can't I am obviously going through perimenopause…
★★★★★ This used to be an amazing app years ago! The redesign IS AWFUL! It had a flower on ovulation day and much easier to navigate with better icons. Now it lacks any visuals and it lags. It takes forever just to click to…
★★★★★ So I have used this app for a while now and their newest update is the absolute worst! I get very irregular periods and on their old design I used to be able to have a nice list of the start and end dates of my period.…

Price and subscription5%

12 of the 1 and 2 star reviews.

★★★★★ I enjoyed this app for a while. With every update comes more disappointment. They want you to pay for everything they can squeeze out of you. Such a weird flex.
★★★★★ I wish I had read the reviews more seriously before paying for a year long subscription, as some of them are 10 years old (probably when the app was last updated).
★★★★★ I haven't been able to obtain a refund either.
WHAT THEY ASK FOR
  • I wish I had read the reviews more seriously before paying for a year long subscription, as some of them are 10 years old (probably when the app was last updated). 1★, Jun 25, 2025
  • Just wish they still had the section where you choose the discharge characteristics of that day. 5★, Sep 8, 2024
  • I wish the app still had the function to show my Fertile window in the cycle window and calendar window 4★, Jul 24, 2024
  • This app is extremely helpful to me, but it would be great to get help with finding good and trusted resources to help me with my period like pads, swimsuits, and even underwear for periods. 4★, May 8, 2024
  • i wish there was a better remedy for something like this since the point of an app like this is to click a button and forget about the rest. 1★, May 5, 2024
  • I also wish they brought back a calendar layout. 3★, Apr 2, 2024
  • I love this app but premium, it should be free because everything else in the app is free except some of the diet and exercises are with premium so I think you guys should let everything be free in the app because all… 5★, Feb 1, 2024
  • I wish that I could revert to the original version. 1★, Sep 19, 2023

Latest reviews, United States App Store.

★★★★★Oct 8, 2026
No longer accurate

Since my wife started perimenopause and her periods are irregular the data no longer shifts when the information is entered. So if her period starts in the middle of the predicted ovulation cycle the app no longer adjusts the dates.

★★★★★Jul 8, 2026
Period Log Won’t Save

I started my cycle and went to enter it days later and it won’t accept the old date. It’s very frustrating.

★★★★★Jun 30, 2026
New Update fixed Issue

After you all posted a new update, the app is now working again, and I am soooo happy! 😃 I didn’t lose any of my saved information.

★★★★★Jun 10, 2026
Been tracking with this for years

Simple and keeps data in one place. Love it!

★★★★★May 28, 2026
Works, but AI

The app works great for tracking and has some cool meditation and workout things, but its privacy policy states it submits all your data to OpenAI and uses AI to create their content,

★★★★★May 21, 2026
Easy and Reliable

Great tracker and predictor
