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.; Gleamer radNet, an imaging provider that competes with many independent Gleamer customers, now owns the company and also owns the competing DeepHealth AI portfolio, so roadmap and pricing priorities are an open question for non-RadNet buyers.
  • They diverge on capability: Flo covers Cycle and ovulation tracking, Gleamer covers BoneView.
  • 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.

Gleamer

  • RadNet, an imaging provider that competes with many independent Gleamer customers, now owns the company and also owns the competing DeepHealth AI portfolio, so roadmap and pricing priorities are an open question for non-RadNet buyers.
  • The measured benefit is largest for less experienced readers, so a specialist musculoskeletal service will see far less improvement than the published reader studies suggest.
  • Cleared indications differ per module and per market, and the FDA cleared set is narrower than the CE marked European set, so an American buyer cannot rely on European reference sites.
  • Each additional module adds alert volume into the same worklist, and departments running several Gleamer algorithms report needing local threshold tuning to keep radiologist trust.
  • Pricing is per exam and not published, which makes budgeting difficult for an emergency department whose plain film volume swings seasonally.

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.

Gleamer: Who owns Gleamer?

RadNet agreed to acquire Gleamer in February 2026 for around two hundred and fifteen million euros upfront. RadNet also owns DeepHealth, a competing AI portfolio.

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.

Gleamer: Is BoneView FDA cleared?

Yes, BoneView holds 510(k) clearance including for paediatric fracture detection, but the cleared finding set is narrower than the CE marked indication in Europe.

Flo: Is Flo free?

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

Gleamer: What does the evidence actually show?

Multi-reader studies reported improved reader sensitivity for fracture detection and fewer false negatives, with the gain concentrated among less experienced readers in emergency settings.

Gleamer: Can I buy just BoneView?

Yes, modules are licensed individually, though the commercial pitch is now the Copilot bundle across modalities.
