Comparison · as of 2 September 2026
WearLink vs Spike
A wearable and medical-device data API with a large device catalogue, enterprise compliance claims and an MCP layer aimed at AI agents; acquired by Raintree Systems.
Spike sells breadth: 40+ providers and 500+ devices through one SDK, medical IoT sources such as Dexcom and Abbott alongside consumer wearables, and a compliance page that lists HIPAA, GDPR, CCPA and ISO. Since its acquisition by Raintree Systems it is positioned squarely at healthcare enterprises.
WearLink is narrower and cheaper to start with: 14 providers, 8 connectable today, flat tiers from free to $399 a month, isolated single-tenant hosting with Asia-Pacific data residency, and nutrition in the same API. It does not have an attestation report yet and says so.
If your buyer is a hospital system or a large payer, Spike is the more defensible choice today. If you are a product team that wants to connect the major wearables this week without a $450-a-month sandbox, WearLink is built for that.

When Spike is the better choice
Spike has the catalogue and the medical sources
If you need CGMs, blood-pressure cuffs and clinical devices beyond the consumer wearables, or a long tail of regional brands, Spike covers ground WearLink does not. Dexcom is still in onboarding on our side.
Spike clears enterprise compliance reviews
Spike lists HIPAA, GDPR, CCPA and ISO. WearLink has not commissioned a SOC 2 or ISO audit. A questionnaire that demands an attestation report is a hard blocker for us today.
Backed by a larger healthcare company
Raintree Systems owns Spike, which matters if your procurement weighs vendor longevity. WearLink is an independent, engineer-run company and is early.
Where WearLink is the better fit
You can start for free, today
Spike's entry point is a $450-a-month sandbox. WearLink issues an API key at signup, the free tier covers 3 connected users, and the first paid tier is $99 flat.
A bill you can predict
Spike describes its pricing as usage-driven and does not publish the rates. WearLink's tiers are flat: an unusually active user does not change the invoice.
Intake and burn in one place
Spike covers device data. WearLink adds photo-based meal logging and a calories-in versus calories-out endpoint against the same user record, so you do not integrate a second nutrition vendor.
