### 2/5 — Suddenly Inaccurate

*2026-08-24, version 10.4.0*

I’ve been using this app for over a decade and it’s been very accurate. All of a sudden it was completely off. Then I got a notification that said “our AI predicts you’re getting your period today” I’m not, it’s weeks off. Why did we incorporate AI if it’s going to ignore a decade of tracking? This app is essentially a calendar now…I have PMDD and it’s really useful (vital) to track my cycle so this update is really upsetting to me. If it doesn’t improve I will probably cancel my premium subscription

### 4/5 — Dil

*2026-08-23, version 10.4.0*

Türkçe dil desteği olsa her şey daha güzel olurdu 🫶

### 1/5 — Paid app that collects a lot of your data

*2026-08-23, version 10.4.0*

The collect all this personalized health data on you before you can even assess what the paid plans are. Not transparent at all

### 5/5 — There should be no cost to help

*2026-08-23, version 10.4.0*

Has to pay for stuff when shouldn’t help be free

### 1/5 — terrible selfish app

*2026-08-23, version 10.4.0*

you don't care about our bodies or health, you only care about our money. the fact that we have to subscribe just to learn about our bodies is so sad

### 1/5 — Doing too much

*2026-08-23, version 10.4.0*

I was looking for a free simple app just to track my periods and ovulation as my form of bc. They asked me everything under the sun just to get to the end to see that they charge…I understand charging but going through all that was doing the most I’m surprised they didn’t ask what my credit score was

### 5/5 — I love my girlfriend

*2026-08-23, version 10.4.0*

I hate periods sooooo much and they should never have hurt women as much as they do. Go feminism!
