Clue Period & Cycle Tracker reviews
What users love and hate · 500 reviews analyzed · ★ 3.1
A respected, women-built cycle tracker with accurate predictions and educational articles that users loved for years — but relentless subscription pop-ups and paywalling of once-free features have turned it into a source of frustration.
What users love
Accurate predictions, especially for irregular cycles
The app's core strength: it genuinely predicts periods and fertile windows accurately, using your own data rather than generic averages. Users with irregular cycles value it most — many credit it with helping them understand their body and even conceive.
out of all the apps I've used, this one has been the most successful at actually predicting my very irregular cycles using the data I give it, not just spitting out averages like other free apps
this app has been on point with my cycle! after using it for 3 months it's been 💯 correct every month
I absolutely love the app. It helps so much since I have irregular periods.
Educational articles and data privacy are what users love
Beyond tracking, the app is praised for educational articles on cycles, pregnancy and menopause, and a clean, non-'childish-pink' design. Its privacy policy is valued in particular — especially post-Roe v Wade — along with the fact that many features really are free.
The most helpful thing I found was the articles you can read on clue. It helped me before getting married and helped with understanding how my body ovulated
I appreciate Clue keeping your info private after the overturning of Roe v Wade. I like both the calendar & analysis features.
super clean, NOT frilly and pink ! I love it. 10/10 would download again.
What users hate
A Clue Plus pop-up fires on every single tap
By far the most common complaint: the subscription ad appears when you open the app, switch to any screen, and after every symptom you log. People describe it as a 'log a day, close an ad' game, 3-4 pop-ups per action, and leave for competitors despite years of stored data.
Every button press is followed by an ad for the pro version, which you have to try to exit out of 3-4 times before it closes. Open the app? Ad. Want to add tracking for the day? Close this ad first.
open it - prompt. Log something - prompt. Switch tabs - prompt.
literally asks you to upgrade to a paid plan every single time you open the app or every single time you track a day
After an update the app won't open — just an endless spinner
A whole wave of reviews: after a recent update the app hangs on a white screen with a spinning circle and won't load for days. Reinstalling helps only temporarily or not at all, and access to years of history — even to a paid subscription — disappears.
New update has broken the app. Unusable. Just has loading screen
i updated but the app its still just showing me the spinner, it wont load... update: app has been broken for 3 days now
The app stopped working altogether. All I see is a white empty infinite loading screen. Force stopping, clearing the cache and re-launching the app did not fix the issue. I also have an active subscription
Once-free features got moved behind the paywall
Long-time users (5-13 years) are furious: things that were free for years — trends, cycle history, sleep tracking, ovulation estimates, offline tracking — are now locked behind a subscription. It reads not as new paid features but as taking away what was already there.
what you used to get back then FOR FREE, to what you get now for free is ridiculous. You used to be able to see trends and patterns etc, but now you need to pay to see them
Good app until a lot of features became paywalled. You can no longer view when your predicted period will be multiple months in advance in the free version
I used to be able to share my cycle with my husband for free, and I can't do that anymore.
You can't edit or delete dates entered by mistake
An infuriating gap in core mechanics: if your period comes early/late or you tap the wrong day, you can't fix the date — and sometimes editing is itself paywalled. The app even logs phantom periods on its own with no way to delete them, wrecking the analysis.
it will randomly log periods and flow variations out of nowhere and there is no way to correct the information to make sure you're getting a good analysis
If I accidentally track something for the wrong day, I can't even edit it anymore without paying.
could never edit my period dates if it ended before my usual time frame
Login failures and lost accounts lock you out of your data
Sign-up and login frequently break: an error on account creation, password-reset emails that never arrive or lead to a 404, the system claiming an email both already exists and doesn't. Even paying users get locked out of their own history.
as soon as I tried to sign up it says " name & email " which I put my information in and it keeps saying " error ". It will not let me sign up for this app
When I tried to reset my password they send me a faulty link that leads to a 404 error page! So now I'm locked out!
Cannot register as it doesn't recognise my email address and/or says its already in use. It isn't, nor can I reset my password
Chaotic billing and no way to get a refund
Charges hit without warning — sometimes two subscriptions at once or after the app was deleted; cancelling is hard because it's hidden, and refund requests go unanswered even where EU law requires them. There is effectively no support.
I was charged for two subscriptions (monthly and yearly) totaling $60 and theres no way to get a refund.
it signed me up for a yearly subscription long after I deleted it and took a LOT of money from my account
I have just been billed for a subscription to this app and have no recollection of downloading the app in the first place
Advertised as free, but the key functions cost money
Many are drawn by 'free' ads, but the free tier is a bare calendar: fertility, pain intensity, analytics and articles sit behind a trial or subscription. People are especially angered at paying just to track a cycle or to try to conceive.
this shows up as a free app but it's actually a monthly subscription
Can't even have fertility checker unless you join the monthly plan. Since when do period apps need a monthly plan?
not free, the free trial is only 14 days, I cannot track my monthly symptoms in 14 days.
No integration with Samsung watches or Health Connect
A frequent wish even among happy users: the app can't link to Samsung watches, Samsung Health or Health Connect, so sleep and activity data must be entered by hand. For many this is the sole reason they hold back the fifth star.
I can't pair with samsung health, so now I have to insert all my sleep and exercise data by hand..... The app is really cool but if I could connect to samsung health I would keep it.
My only complaint is that there is no way to connect my Samsung watch.
there is no way to connect to samsung health or health connect so I can sync the data in my health app
Clue Connect for partners is nearly useless and paywalled
The partner-sharing feature disappoints: it's one-directional, doesn't show moods or other markers, is unhelpful for conceiving, and yet requires both partners to pay for a single cycle. The previously free sharing with a husband was removed too.
after paying for a year, we realized that it's actually pretty unhelpful for partners. She wanted for me to be able to see her moods/other markers
given a code by my wife so thought i could track her cycle on my phone to help us conceive. No, it says I have to pay as well. why do both have to pay to track one cycle??
the "Clue Connect" feature that allows you to share your cycle with a partner is unidirectional
The 13+ age gate shuts out real young users
Girls aged 9-12 who already menstruate can't register because of an 'underage' block — exactly those who need tracking most. Parents can't set up a profile for a younger daughter either, and the app has no multi-profile support.
I'm TEN), I need to track my periods, especially since im low on clothes now from it.
why do i need to be +13? im 11 and I just wanna track when im finna bleed again😭
the app wouldn't let me because she's younger than 13, there should be an option for these girls because my sister is eleven, got her period at nine
