Where each one falls short

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

Clue

  • Clues stated policy on not sharing data with law enforcement without a valid legal process is the companys own published position and legal interpretation, not an independent guarantee, and it can still be compelled to comply with a legally binding request under EU or other applicable law.
  • Deeper cycle insights and predictions, the features most likely to justify tracking in the first place, are gated behind the Clue Plus subscription rather than fully free.
  • Being a smaller company than some competitors, Clue has less capital and legal resource to contest large-scale legal requests than a larger, better-funded rival might, despite its stated intent to do so.
  • Research partnerships using anonymised user data, while opt-in, still mean user-derived data can be used in ways beyond direct app functionality, and users should check current consent settings.
  • Cycle predictions rely on self-reported data and general population models, so accuracy for irregular cycles or specific medical conditions remains limited regardless of which app is used.

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
