The store currently lists version 10.7.0, updated 2026-09-27.
What the analysis found
The catch list 3
Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.
One source only — shown, not confirmed 5
A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.
What reviewers said
Verbatim excerpts from public store reviews, shown as corroborating user reports. They are not Appworthy audit evidence, and a quotation is not proof of the finding it sits under.
Aggressive ad load
Money grabbing full of ads — I’m really disappointed with this app. It now has so many adverts to subscribe and pay, it’s difficult to avoid them. I accidentally clicked one this week and it charged me £27. I immediately tried to request…
FINALLY DELETED THIS APP😁😁😁 — i have had this app forever, over the years they have gotten worse and worse with pushing the paid part onto me, sometimes you can’t even use the app because it bombards you with so many adds and try’s to…
Too many ads — Anytime I click something on the app, they always shove the subscription in my face. You then need to press a bunch of buttons to exit. It’s very annoying
Paywall blocks the basics
FINALLY DELETED THIS APP😁😁😁 — i have had this app forever, over the years they have gotten worse and worse with pushing the paid part onto me, sometimes you can’t even use the app because it bombards you with so many adds and try’s to…
Flo review — You have to pay for everything I’m 13 I rarely have money of mine Own all I do on Flo is calculate my cycle
Constantly pressuring you to Subscribe — It’s good for tracking and luckily they don’t force you to subscribe to log your cycles but every other feature it pressures you into it. Can’t open the app without being asked to sub for a year…
Upgrade prompts use guilt-trip wording
Constant pestering to subscribe — It’s a good app but the constant pestering to subscribe every time you open it is so annoying and invasive. You have to click like 3 different pop-ups to close it and ignore 3 different “offers” and…
Keep asking for money — App works fine, just annoying they keep asking me to pay without a way to exit the pop up
Reduce pop ups — I’ve used this app for over 5 years and enjoyed the interface and design. In recent years it had been frustrating to even open the app due to the amount of pop ups wanting you to subscribe to their app. It is embarrassing…
Trial converts to a charge
Pop-ups and selling your data — Constant popups. Lawsuit over data selling with Google. Charge you for free trial if done within App Store. Features force use of paid version.
Scam — I signed up for their free trial, but they immediately charged my card even though I have never done their free trial before. I requested a refund, and thankfully they granted me that. However, this week they charged my card again…
Dishonest free trial — I selected free trial and they automatically charged me 19.99$ no they do not want to reimburse me
Hard to cancel
Horrible, cannot cancel — This app is still charging me monthly, even though I have canceled. I got sucked in to the “try it for $1”. I was just looking for information, I would never pay a monthly fee for this. When I log in, it says I…
Awful — Awful app. Works great for period tracking but charged me $60 and won’t let me cancel my subscription. I’ve tried numerous times and customer service stopped responding.
Avoid!! — Impossible to cancel your subscription which you’re forced to get to see your results. It’s got me in an endless loop cycling between the app and the website but you can’t cancel.
Reports that the ads misrepresent the app
Save your time and money — Never have I ever written a review for an app in my 30 years so this one takes the cake. I’ve had this app for about six months and every time I go on it I just get frustrated. One of the worst apps with the…
Reports of unexpected charges
Horrible, cannot cancel — This app is still charging me monthly, even though I have canceled. I got sucked in to the “try it for $1”. I was just looking for information, I would never pay a monthly fee for this. When I log in, it says I…
FRAUD — I didn’t sign up for premium yet it started to charge me 24.99 usd a month and not giving me any benefit because each time I tried to enter information it was asking to upgrade. On top of that you can’t easily unsubscribe via the…
Don’t recommend — I didn’t even have a log in and they took my money .!
Tracking and data collection concerns
User for many years but don’t recommend it — Overall if u just require basic tracking, the free version should be sufficient. TLDR: I have been using Flo for many years. Thankfully, it help me to learn that my flow is in fact regular. I…
Useful but Annoying — Yeah the calendar is useful and the extra resources can be insightful. BUT YOUR APP IS SO F* ANNOYING I TRY TO SPEND THE LEAST AMOUNT OF TIME POSSIBLE ON IT. I swear the copying of the Temu ‘promotion/gift’ reveals…
Too many adverts — The second you open the app you are bombarded with adverts. It makes the app almost unusable. On top of that, the app sells your data. I am switching to an ad-free app with better accuracy.
How the automated analysis works
This assessment is produced automatically. Three independent signals are read — user reviews, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Several measurements above say “Not assessed” because no artefact we hold can answer them. A human review is what resolves those — and it can remove a favourable band as easily as add one.
Hands-on inspections are not yet open.
