The short version

  • Only Flo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Flo flo Health settled with the US FTC in 2021 over allegations it shared sensitive health data, including pregnancy and menstruation details, with Facebook, Google and other third parties despite telling users the data would stay private, a fact directly relevant to how much a user should trust current privacy claims without independently checking the published policy.; Therapixel european and American regulatory positions were established under different regimes, and under the EU Medical Device Regulation this class of diagnostic AI faces a higher classification and notified body scrutiny, so European buyers must verify the current MDR certificate and expiry rather than relying on a legacy CE reference.
  • They diverge on capability: Flo covers Cycle and ovulation tracking, Therapixel covers MammoScreen 2D.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Flo

  • Flo Health settled with the US FTC in 2021 over allegations it shared sensitive health data, including pregnancy and menstruation details, with Facebook, Google and other third parties despite telling users the data would stay private, a fact directly relevant to how much a user should trust current privacy claims without independently checking the published policy.
  • Reproductive health data, including logged periods, fertility attempts and pregnancy status, has been the subject of law enforcement data requests in some jurisdictions following changes to reproductive rights law, and cloud-stored logs are a real category of exposure regardless of a vendors intentions.
  • Anonymous Mode, the privacy feature introduced after the settlement, is a setting that must be checked and understood rather than assumed, and its exact scope and default status should be verified in the current privacy policy rather than taken from marketing copy.
  • Free tier predictions rely on self-reported symptom data and general population models, so accuracy for irregular cycles or specific medical conditions is limited compared with clinical tracking.
  • The subscription auto-renews and, like most mobile subscriptions, must be cancelled through app store account settings rather than inside the app itself.

Therapixel

  • European and American regulatory positions were established under different regimes, and under the EU Medical Device Regulation this class of diagnostic AI faces a higher classification and notified body scrutiny, so European buyers must verify the current MDR certificate and expiry rather than relying on a legacy CE reference.
  • MammoScreen does mammography only, so a hospital wanting AI across head CT, chest and breast needs several vendors and several PACS integrations, or an orchestration layer bought from someone else.
  • Therapixel is a small French company competing against Hologic and iCAD, which have incumbency inside the mammography reading workstation, so integration into an American breast centre is more work than it is for the workstation vendor own AI.
  • Detection performance is sensitive to the mammography unit vendor and acquisition protocol, so published results do not transfer between estates and each site needs local validation it must fund itself.
  • Whether AI can substitute for one of two human readers is a national workforce and liability question, not a product capability, so the labour saving that justifies the purchase in one country is not permitted in another.

Answered from the vendors’ own pages

Flo: What happened with the FTC in 2021?

The US FTC alleged Flo Health shared sensitive health data, including pregnancy and menstruation details, with third parties like Facebook and Google despite promising to keep it private. Flo settled without admitting liability, agreeing to obtain consent for future sharing and to an independent privacy review.

Therapixel: Is MammoScreen FDA cleared?

Yes. It holds 510(k) clearance K192854 for two dimensional mammography from July 2020, a November 2021 clearance for digital breast tomosynthesis, and two further clearances in October 2024 for later versions.

Flo: What is Anonymous Mode?

A privacy setting Flo states disconnects entered health data from an identifiable profile. Check the current app and privacy policy for whether it is on by default or must be turned on manually, since this affects what data is linked to your identity.

Therapixel: Is it CE marked?

Yes, but European buyers should ask specifically for the current certificate under the Medical Device Regulation and its expiry date, because this class of diagnostic AI moved to a higher classification under MDR.

Flo: Is Flo free?

Core cycle tracking and predictions are free. Deeper personalised insights and expert content require Flo Premium.

Therapixel: What does the one to ten score mean?

It is a graded suspicion score per finding and per study, designed to be integrated alongside a radiologist BI-RADS assessment rather than treated as a positive or negative result.

Therapixel: Does it cover anything besides mammography?

No. It is a mammography product only, including tomosynthesis. Other body regions need a different vendor.
