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.; Rad AI the products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.
  • They diverge on capability: Flo covers Cycle and ovulation tracking, Rad AI covers Impressions.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Flo

  • Someone tracking cycle and ovulation who wants to weigh app convenience against the sensitivity of the data being loggednot Rad AI
  • A user in a jurisdiction with legal risk around reproductive health data who wants to check Anonymous Mode and current data sharing policy before logging pregnancy or fertility attemptsnot Rad AI
  • A buyer wanting to compare Flo directly against Clue on published data practices before choosing which app to trust with this informationnot Rad AI
  • Someone who wants pregnancy tracking content alongside cycle tracking in one app rather than switching apps mid-pregnancynot Rad AI

Rad AI

  • A private radiology practice whose read volume has grown faster than it can recruit and that wants dictation time per study reduced without changing PACSnot Flo
  • A health system losing revenue and exposing itself to liability because recommended follow-up imaging on incidental findings is never bookednot Flo
  • A radiology department standardising impression quality across a mixed group of employed and locum radiologistsnot Flo
  • A group deploying an AI tool that must not trigger a device validation programme, because governance capacity is already consumed by a triage algorithm rolloutnot Flo

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.

Rad AI

  • The products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.
  • Generated impressions require radiologist review and signature, so the time saving evaporates in any group whose radiologists rewrite the draft rather than edit it, and adoption varies sharply by individual.
  • It is bound to your dictation platform, so a group planning to move off PowerScribe should sequence that decision first or expect to redo the Rad AI integration.
  • Continuity depends on the quality of recommendation language in historical reports, and departments with inconsistent phrasing get poor recall until reporting practice is standardised.
  • Pricing is not published and is structured per radiologist or per study depending on the product mix, which makes it hard to compare against image-analysis AI vendors that price per scan.

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.

Rad AI: Is Rad AI FDA cleared?

No, and by design. The products draft text and manage follow-up workflow rather than interpreting images, so they fall outside the device pathway. Treat any diagnostic accuracy claim with scepticism.

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.

Rad AI: Does the radiologist still sign the report?

Yes. Output is a draft that the radiologist reviews and signs; nothing is released autonomously.

Flo: Is Flo free?

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

Rad AI: Which product actually pays for itself?

Continuity has the clearest financial case, because recommended follow-up imaging that gets completed is billable work that currently does not happen.

Rad AI: Will it work with our dictation system?

It is deepest with Nuance PowerScribe. Confirm your specific dictation and PACS combination before contracting, because integration depth is the main deployment variable.
