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.

Open Dental

  • US support is $199 per month per location on an initial 12 month contract, dropping to $149 per month only after that year
  • The monthly fee covers up to 3 providers per location; each additional provider is $20 per month
  • Fees are charged per location, so a multi site practice pays for every office
  • eServices are charged separately per location, including eClipboard at $45 a month, ODMobile at $35 a month and eConfirmations at $25 a month
  • Electronic prescribing through DoseSpot costs $57 per month per prescribing provider
  • Conversion and implementation fees are not published and require consultation
