Is Flo legit?

Legit

You can rely on Flo being what it says, a period, ovulation and pregnancy tracker used by millions, but Flo Premium keeps renewing until it is properly cancelled. Deleting the app or even your account does not end it, and a free trial turns into paid billing unless cancelled a day before it ends.

What we checked

  • Founded in 2015
  • UK company registered in London
  • Ratings on other review websites: 4/5

Watch out for

  • Charges that continue after deleting the app or your account, since neither cancels Flo Premium.
  • A Premium discount from a promo code that ended, with the plan carrying on at full price.
  • Health data you want removed, where Flo offers no partial deletion, only deleting the whole account.

Billed for Flo Premium after deleting the app?

We help you write it, it gets its own public page, and you can have it sent to Flo as a formal letter.

Common customer service questions about Flo

How do I file a complaint about Flo?

Do you have a dispute or a bad customer experience with Flo? Report it through our website to maximize the chance of getting it resolved.

We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.

How do I contact Flo customer service?

Flo customer service runs through the Flo help centre, linked in the contact details above, and by email at support@flo.health; inside the app, the Contact us option under Profile and Help opens a request. Include the email address on your Flo account, where you bought the subscription, the receipt or order number, and screenshots of the problem.

Billing or account problem to raise? Start your complaint here as well, and we push it out to Flo by email, social media and printed letters.

Does Flo have a customer service phone number?

Flo publishes no customer service phone number: support runs through its help centre, the Contact us option in the app and email at support@flo.health. Write from the email address on your Flo account, or give it in your message, so the request can be matched to your subscription. For a subscription bought through the App Store, refunds go to Apple rather than Flo.

Need a billing problem set out in writing? We help you write the complaint in minutes, with the receipt, dates and account email in order.

How do I cancel my Flo subscription and get a refund?

How you cancel Flo Premium and ask for a refund depends on where you bought it, so check whether your receipt names Apple, Google Play or Flo Health. Bought through the App Store: cancel in your Apple subscription settings and ask Apple for the refund, because Flo says Apple handles those refunds. Bought through Google Play: cancel in Google Play, then ask Flo through Contact us in its help centre, giving your Google Play order number. Bought on the Flo website: cancel in the app under Profile and Manage Subscription, or at app.flo.health under Subscriptions, and ask for a refund through Contact us or support@flo.health with the receipt. Deleting the app does not cancel a subscription, and cancelling stops future charges without refunding one already taken.

Charged again after cancelling? Raise it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply and when to push again.

How do I delete my Flo account and data?

To delete your Flo account, open the app, tap your avatar to open the menu, choose Privacy settings and then Delete account, and follow the steps. Flo says deletion is irreversible and removes all your data permanently, so request a copy of your data first if you want one. Deleting the account may not stop a paid subscription, so cancel Flo Premium first where you bought it and keep the confirmation.

What do people complain about most at Flo?

Nothing has been reported about Flo here yet. Our research shows what typically goes wrong at subscription health apps: trials that roll into a paid plan, charges that continue after the app is deleted, refunds that depend on whether Apple, Google or the app itself took the payment, data lost after a phone change, and questions about how sensitive health data is stored and deleted.

Trial turned into a yearly charge you did not expect? Be the first to report it: your case opens the record the next user checks before starting a Flo trial.

What happens after I submit my complaint?

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Flo through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my Flo complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Flo can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
