### 1/5 — Forgot password

*2026-08-23, version 291.0*

I was signed out & tried login in with forgot password & never got the email for password reset after trying so many times. I had to re sign in again & all my data was lost. So so disappointing.

### 1/5 — Won’t let me update

*2026-08-22, version 291.0*

Won’t let me update

### 3/5 — Unfortunate update

*2026-08-22, version 290.0*

To echo other comments, yes the recent updates to UI & free options is unfortunate. I’m unemployed after years of burnout and have long dealt with heavy, irregular, painful periods. Tracking is helping me have something to show my dr. as I try to help myself and get prepared to inevitably go back to working. 

But it does suck to feel like you have to have money to properly track & generally have concern about your health. I understand we are in an economic system that requires monetization and in a time where women continue to be swept under the rug as well as social care/welfare in the US generally... I appreciate all that you guys do, I just wish all of this weren’t so exhausting on our end.

### 3/5 — good app, but the ads are obnoxious

*2026-08-20, version 290.0*

I’ve been using Clue for a few years. It’s a good period tracker, but the constant ads for Clue+ are overwhelming. There should be a way to decrease the frequency of them and it takes away from the app’s experience

### 5/5 — Useful app

*2026-08-20, version 290.0*

I appreciate the practicality of this app, have used it for years, and I appreciate you getting rid of the “men can get periods” propaganda (imo) that you used to feature.

### 5/5 — Love it

*2026-08-20, version 290.0*

I love this app it has made it so much easier to track when I will have my period and it is very accurate ♥️♥️♥️

### 1/5 — So useful

*2026-08-19, version 290.0*

Update:
Many years later, and this app is the worst. It seems every month they take away more and more features and put them on their premium account which is a subscription 🙄 Like I’m going to pay for a glorified calendar! It used to be nice to track things like pain, skin, pms symptoms etc and actually have their statistics and patterns. You can still have your own custom tags but they are useless because you can’t access any stats on them. Now, all of that is behind a paywall. Even basic statistics about my period don’t exist, just a calendar and averages, which doesn’t tell me if anything has shifted in recent months or anything. On top of the free version being utterly useless, they spring ads for the premium subscription at least 1-3 times every time you open the app, which is excessive since you might only open it a few times a month. AND, the ads are very hard to close, with the “X” button always hidden within a very similar-colored background.
Apple Health app can do everything this app can do, which is just very basic period tracking. Don’t bother with Clue.

Initial Review: You can set custom reminders for so many things, and track so much more than just periods and PMS. I like that I can track my skin, mood, energy level, digestion, and see if there are any patterns. Been using clue regularly for over a year, its a good one!

### 3/5 — It’s ok

*2026-08-19, version 290.0*

It’s good but you have to pay for a lot of features but ok if you just want simple features

### 3/5 — Pop Ups

*2026-08-19, version 290.0*

I’d probably rate the app better if I wasn’t constantly bombarded with the pop ups trying to make me pay. It’s really freaking annoying and I’m thinking about deleting.

### 2/5 — Dont waste your time

*2026-08-19, version 281.0*

This app is riddled with pop-up promotions and fails at the one thing I set it up to do:  remind me X days before my period. Everyday I get a useless notification asking how I feel, but I can't get the one notification I opted in for. Super disappointing overall.
