Hinge Health vs Sword Health (2026)
The two digital musculoskeletal heavyweights sell to the same buyer, self insured employers and health plans, and both pair AI with licensed clinical teams, so the choice runs through measurement and proof. Hinge Health's distinctive asset is objective measurement: TrueMotion turns an ordinary smartphone camera into a 3D motion assessment tracking 87 reference points, feeding joint angles, symmetry, and endurance into HingeScore, in a field where established musculoskeletal outcome measures rely on patient self report. Sword Health's distinctive posture is the pairing itself: its Phoenix AI care specialist works alongside a licensed Doctor of Physical Therapy who stays in the loop for every member, with reported scale of more than 800,000 members and over 1,000 clients. If your failure mode is trusting self reported outcomes, start with Hinge. If your failure mode is AI care without a named clinician attached to every member, start with Sword. Both price by contact, and every headline figure in this lane is vendor published.
- Objective measurement is your requirement: TrueMotion detects 87 reference points across the body from an ordinary smartphone camera with no specialised equipment, and Movement Analysis combines joint angles, symmetry, and endurance with questionnaires into HingeScore, in a field where established outcome measures rely on self report.
- The computer vision pedigree is real: the 2021 wrnch acquisition brought motion tracking of the class used in elite sport and film, and the company stated it gave it the largest computer vision team in digital health.
- A stated governance posture with a cleared hardware adjunct: published AI care principles govern development across the platform, and the Enso wearable holds FDA clearance for pain relief, noting the clearance covers the hardware rather than the AI.
- A named licensed clinician for every member is your bar: Doctors of Physical Therapy pair with the Phoenix AI care specialist in the musculoskeletal programs, with the specialist type varying by product line.
- Program breadth on one platform: musculoskeletal care through Thrive, women's health through Bloom, and cardiometabolic care through Pulse, announced for later 2026 with outcomes based pricing.
- Scale signals matter to your committee: reported figures of more than 800,000 members served, 11 million AI care sessions, over 1,000 clients including a fifth of the Fortune 500, and per member musculoskeletal savings of $3,177 a year.
This comparison is published by AI Health Index, an independent research platform that compares healthcare AI vendors objectively. Hinge Health and Sword Health are each graded against the same capability taxonomy, from each vendor's own public materials and the regulatory record, under the AI Health Index verification standard.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached.
The AI Health Index grades Hinge Health A on Deployment Model and Data Residency, and B on AI Centrality, Autonomy and Oversight Model, Model and Technology Transparency, Clinical and Operational Evidence and Setting and Specialty Coverage. It grades C on AI Safety and PHI Stewardship, HIPAA and BAA Posture, Security Certifications and Trust Center, FDA and Regulatory Status, AI Governance and Bias Disclosure, EHR and Interoperability Depth, Commercial Transparency and Model Supply Chain Disclosure, and D on AI Liability and Recourse. The distinctive asset the AI Health Index records is objective measurement: motion assessment from an ordinary smartphone camera feeding joint angles, symmetry and endurance into a composite score, in a field where established musculoskeletal outcome measures rely on patient self report. The grade to read alongside it is governance: pose estimation models as a class carry documented accuracy variation across skin tone and body size, and the AI Health Index has not located published subgroup accuracy from this vendor.

The AI Health Index grades Sword Health A on Autonomy and Oversight Model and A on Security Certifications and Trust Center, and B on AI Centrality, Clinical and Operational Evidence and Setting and Specialty Coverage. It grades C on FDA and Regulatory Status, HIPAA and BAA Posture, AI Safety and PHI Stewardship, Model and Technology Transparency, AI Governance and Bias Disclosure, Deployment Model and Data Residency, EHR and Interoperability Depth, Commercial Transparency and AI Liability and Recourse, and D on Model Supply Chain Disclosure, the lowest grade either company carries. The A on autonomy and oversight is the one that separates the pair: a licensed clinician stays in the loop for every member rather than the AI operating unattended, which is the specific structure the AI Health Index grades at the top of that axis. The supply chain grade is the counterweight, since the model providers and subprocessors behind the AI care specialist are not disclosed where a buyer can retrieve them.

Questions buyers ask
Hinge Health vs Sword Health: which is better for a self insured employer?
Both sell to the same buyer and both pair AI with licensed clinical teams, so the AI Health Index frames the choice around which failure mode the buyer is trying to avoid rather than around which vendor is stronger overall.
If the failure mode is trusting self reported outcomes, Hinge Health is the starting point: its motion assessment produces objective measurement from an ordinary smartphone camera in a field where the established outcome measures rely on patient self report. If the failure mode is AI care operating without a named clinician attached to every member, Sword Health is the starting point, and the AI Health Index grades it A on Autonomy and Oversight Model for exactly that structure against Hinge Health at B.
One caution the AI Health Index attaches to both: every outcome and scale figure either company publishes in this lane is vendor published and has not been independently validated by this index.
Do Hinge Health or Sword Health publish pricing?
Neither publishes rates. Both price by contact, and the AI Health Index grades both C on Commercial Transparency, meaning a self insured employer or health plan cannot establish a cost basis before a sales engagement with either company.
Savings figures do circulate in this lane, including per member annual musculoskeletal savings claims, but the AI Health Index records those as vendor published claims rather than as pricing, because a claimed return is not a rate and cannot be used to build a budget.
Is Hinge Health or Sword Health FDA cleared?
Neither company holds clearance for the AI itself, and the distinction matters more here than the headline suggests. The AI Health Index grades Hinge Health C and Sword Health C on FDA and Regulatory Status. Hinge Health holds a clearance covering a wearable hardware adjunct for pain relief, which is a device clearance rather than a clearance of the motion assessment or the care model.
A buyer reading a clearance claim in digital musculoskeletal care should establish which component it covers, because in this lane it is usually hardware rather than the software doing the assessment.
Do these digital musculoskeletal platforms publish subgroup accuracy?
Neither does, and the AI Health Index grades both C on AI Governance and Bias Disclosure for that reason. This is the disclosure gap that matters most in this specific category. Pose estimation models as a class carry documented accuracy variation across skin tone and body size, so a motion assessment that performs differently across a covered population would produce different care recommendations for different members without anyone in the workflow being told. The AI Health Index has not located published subgroup accuracy from either vendor, and recommends asking for it directly, along with the composition of the population the models were validated on.

Every outcome and scale figure in this comparison is vendor published, including Sword's savings and avoided cost claims and Hinge's measurement claims; none has been independently validated by this index. Hinge's FDA clearance covers the Enso hardware, not the AI. Pose estimation models as a class carry documented accuracy variation across skin tone and body size, and this index has not located published subgroup accuracy from either vendor. Sword is indexed for its business to business products only, not its 2026 consumer application. Both companies price by contact; neither publishes rates.
