The short version

  • Only Clue has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Fujifilm Synapse pACS, VNA, Cardiovascular and 3D are separately licensed and separately versioned, so an enterprise deployment means four upgrade cycles and four support relationships under one brand rather than one platform upgrade.
  • They diverge on capability: Clue covers Cycle and symptom tracking, Fujifilm Synapse covers Synapse PACS.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Fujifilm Synapse

  • A hospital replacing PACS that wants the archive decoupled from its scanner vendor so future modality purchases stay competitivenot Clue
  • A health system consolidating radiology, cardiology, ophthalmology and wound images into one vendor neutral archive with a single retention policynot Clue
  • An outpatient imaging chain that needs one worklist across multiple sites and radiologists reading remotelynot Clue
  • A site pursuing a deconstructed PACS strategy that wants to replace the viewer later without touching the archivenot Clue

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.

Fujifilm Synapse

  • PACS, VNA, Cardiovascular and 3D are separately licensed and separately versioned, so an enterprise deployment means four upgrade cycles and four support relationships under one brand rather than one platform upgrade.
  • Synapse 3D is licensed by concurrent user and sized from average concurrency, which leaves radiologists queued for advanced visualisation at the morning reading peak and forces an unplanned licence purchase.
  • As an independent informatics vendor Fujifilm has less privileged access to proprietary modality data than Philips or Siemens have on their own scanners, so some vendor specific post processing is not available.
  • The vendor neutral archive absorbs non DICOM object types only after per specialty configuration work, and departments such as ophthalmology and dermatology usually need bespoke ingestion projects that were not in the original scope.
  • Migrating a decade of priors from a legacy archive is a large professional services line that Fujifilm quotes separately, and these migrations regularly run past the contracted go live date.

Answered from the vendors’ own pages

Clue: Does Clue share data with law enforcement?

Clue publishes a policy stating it does not share health data with law enforcement or public authorities without a legally binding request and states it will challenge requests it considers improper. This is the companys stated position; verify the current policy directly for specifics.

Fujifilm Synapse: Is Synapse one product or several?

Several. Synapse PACS, Synapse VNA, Synapse Cardiovascular and Synapse 3D are separately licensed products under one brand. Price and scope each one individually.

Clue: Why does Clue emphasise being an EU company?

Clue operates under EU GDPR data protection rules and states this legal basis makes it harder for authorities outside the EU, including US authorities, to compel data disclosure than for a company based in the US.

Fujifilm Synapse: Do I have to buy Fujifilm scanners?

No. Fujifilm sells Synapse independently of imaging hardware, which is a large part of why it wins competitive PACS replacements at mixed fleet sites.

Clue: Is Clue free?

Core cycle tracking, logging and basic predictions are free. Deeper insights and extended predictions require Clue Plus.

Fujifilm Synapse: Does Synapse publish pricing?

No. Pricing is quoted by study volume, concurrent users, module mix and storage capacity.

Fujifilm Synapse: Can Synapse VNA store non radiology images?

Yes, including visible light, ophthalmology and wound photography, but each specialty typically needs its own ingestion and metadata configuration project.
