I’ve used the app for years and it’s hands down one of the easiest ways to track, but I may have to find another option. I’d love for ONE developer to stop bending to the will of including ads in everything but in this specific case, having a TWO MINUTE ad IMMEDIATELY after opening the app, and not being able to simply make an entry to the calendar until they’re done? Come on y’all….

Worst application, I swear. Ads pop up nonstop, every 3 seconds or something, which makes it impossible to use. Terrible just terrible

I’ve used this app for many years, probably a decade now. I am switching to a new app now. The amount and length of the ads just to track one thing is out of control. It was not always this bad but I simply cannot continue to waste minutes at a time to input one thing. It’s sad because this thing has years of my tracking but I cannot take it anymore.

I’ve used this app for a decade and I can’t do it anymore. The ads are insufferable and so frequent.

The tracker itself is really accurate, but the ads to get to the tracker are horrible! Literally like five minutes long just to log anything

Oct 20, 2025 Update: 12 years since my last review… Although I was annoyed with the app changes posted below 12 years ago, I continued to use the app, as I had already logged data for 5 years. Now 17 years since first use… The app is becoming increasingly difficult to update and check due to so many ads. I was sure I had paid early on for a lifetime subscription, but seem to have lost that Apple ID changes thanks to not being able merge Apple IDs and an Apple tech that just created a new ID for me years ago. In any case, this app seems to not be aging well (not great for tracking symptoms as an older woman). My previous 1-star rating will stay, as the number of ads are overwhelming any functionality of the app and is difficult to access my data quickly in a dr appt, where time is limited. Additionally, the data I have accumulated over the use of this app (17 years), is not compatible with other health trackers like Apple and there is no way to export it in a way that I can import it to use with another tracker app other than by email. So either I lose all of my data or pay for lifetime ad-free access a second time. Feb 28, 2013: Since I started using this app in 2009, this app has only even gotten better & has become part of my routine as an invaluable time saver that I've come to rely on! Unfortunately many of the features I use most seem to have disappeared starting with February 28, 2013. Now it appears as only the Notes field is available for all future dates. Please update this so that the previous options are once again available & I will gladly change my rating to 5 stars! Otherwise is will have to find a new app, as I can no longer make any manual adjustments or functionally track my cycle.

The amount of ads made me delete this app. Absolutely insane!

I have had this app for years. Never used any other but over the past maybe 2 years the ads have gotten longer and more frequent. Looked for a new app today as a result.

I have used the this app for nearly 10 years. It has become completely unusable in the past couple of years. The ads are excessive and I’m sure it’s breaking some sort of Apple Store rules. I will be reporting it.
