Flo

  • 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 Epic Systems
  • A buyer wanting to compare Flo directly against Clue on published data practices before choosing which app to trust with this informationnot Epic Systems
  • Someone who wants pregnancy tracking content alongside cycle tracking in one app rather than switching apps mid-pregnancynot Epic Systems

Where each one falls short

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

Epic Systems

  • No free version or trial; enterprise pricing only with custom negotiation required
  • Lengthy implementation timeline: 12-24 months for single hospitals, 3-5 years for multi-system rollouts
  • Customization and workflow adaptation requires extensive consulting services
  • Very high licensing costs ranging from 100,000 to 30 million USD depending on organization size

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.

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.

Epic Systems: Is there a free trial or demo available?

Epic does not offer a free version or trial. The software is enterprise-only with custom pricing negotiated directly with organizations. Typical implementation timelines for single hospitals range from 12 to 24 months, and multi-hospital systems can take 3 to 5 years for phased rollouts.

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.

Epic provides multiple integration pathways: FHIR R4 APIs, HL7 v2 messaging, CCDA document exchange, and proprietary APIs through Epic Showroom (formerly App Orchard). Over 1,000 certified apps are available in the marketplace, enabling real-time data synchronization and interoperability.
