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.; Sectra sectra does not make scanners, so it cannot cross-subsidise software against modality hardware the way an integrated manufacturer can, and it often loses on headline price in a bundled tender.
  • They diverge on capability: Flo covers Cycle and ovulation tracking, Sectra covers Sectra IDS7.
  • 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.

Sectra

  • Sectra does not make scanners, so it cannot cross-subsidise software against modality hardware the way an integrated manufacturer can, and it often loses on headline price in a bundled tender.
  • Diagnostic AI is not built in house; Amplifier orchestrates third party algorithms, so the algorithms themselves need separate licences, separate clinical validation and separate information governance sign off.
  • Sectra One Cloud is priced against a committed annual study volume, and organisations whose imaging activity grows faster than forecast meet overage charges partway through the term.
  • The pathology module assumes you have already solved slide scanning and laboratory workflow, which is the larger and more expensive part of digitising histopathology and is not in Sectra scope.
  • Depth of Epic and Oracle Health integration varies by region and by which modules you buy, so a reference site in Sweden is a weak predictor of what integration will cost a United States buyer.

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.

Sectra: Does Sectra include diagnostic AI?

No. Sectra Amplifier is a marketplace and orchestration layer for third party algorithms, each licensed and validated separately.

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.

Sectra: Is pathology really on the same platform as radiology?

Yes, the pathology module uses the same archive and workflow engine, which is the main reason buyers digitising histopathology shortlist Sectra.

Flo: Is Flo free?

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

Sectra: How is Sectra One Cloud priced?

On committed annual study volume plus the modules selected, as a subscription rather than a capital purchase. The vendor does not publish rates.

Sectra: Is Sectra CE marked and FDA cleared?

The diagnostic viewing software carries CE marking under the medical device regulation and FDA 510(k) clearance for diagnostic interpretation, but the exact cleared indications differ per module and per market, so confirm for pathology specifically.
