WearLink vs Terra
The best-known wearable data aggregator, with the widest device catalogue and enterprise compliance certifications.
Terra is the default answer to "which wearable API should we use", and for a large class of companies it is the correct answer. It has the broadest integration catalogue in the category, HIPAA and SOC 2 posture that clears enterprise procurement, and enough customers that the failure modes are well understood.
WearLink is a smaller, newer platform with a narrower catalogue and a different centre of gravity: flat pricing instead of credits, isolated single-tenant hosting in the Asia-Pacific region, independent of the US/EU hyperscalers, and nutrition built into the same API rather than bolted on from a second vendor.
The honest summary is that Terra wins on breadth and compliance maturity, and WearLink wins on price predictability, transparent provider status, and having calories-in and calories-out in one place. Which of those matters is a question about your product, not about which vendor is better.

Side by side
| Axis | Terra | WearLink |
|---|---|---|
| Provider catalogue | 500+ wearables and apps | 14 providers — 8 connectable today, 6 in OAuth onboarding |
| Pricing model | Credit-based, from $399/mo; roughly 200 credits per active user per month | Flat tiers — free, $99/mo, $399/mo, custom |
| Cost predictability | Varies with user activity; overage billed per credit | Fixed per tier — an unusually active user does not change the bill |
| Compliance certifications | HIPAA compliant, SOC 2 certified | SOC 2 preparation not yet started; audit-log export and access controls shipped |
| Data residency | US / EU hosted | Isolated single-tenant hosting, data residency Asia-Pacific (Malaysia); additional regions on Enterprise |
| Nutrition data | Not part of the core product | Photo-based meal recognition and an energy-balance endpoint in the same API |
| Self-hosting | Managed SaaS | Managed, with a self-hosted deployment path |
| Maturity | Established, large customer base | Early — small customer base, expect to be an early adopter |
When Terra is the better choice
Terra has far more integrations
If you need a long tail of devices — niche fitness apps, older equipment, regional brands outside South Asia — Terra covers ground we do not. Our catalogue is 14 providers and eight are connectable today. Check that yours is on the list before anything else.
Terra clears enterprise procurement, we do not yet
Terra is SOC 2 certified and HIPAA compliant. WearLink has not started a SOC 2 audit. If your buyer sends a security questionnaire that requires an attestation report, we will not pass it today. That is a hard blocker, not a negotiation.
Terra is a safer bet on maturity
They have been doing this longer with more customers, which means more edge cases already found and fixed. We are early. Early means responsive and flexible; it also means you may be the first to hit something.
Where WearLink is the better fit
Flat pricing instead of credits
Terra bills credits that scale with how active your users are, so a fitness product with heavy users pays more per user than a wellness product with light ones. WearLink tiers are flat: you can forecast the line item before you launch.
Transparent hosting and status
WearLink states exactly where it runs — isolated single-tenant infrastructure with Asia-Pacific (Malaysia) data residency — and publishes a provider status page reconciled against the live API. If your data-transfer analysis needs a named region and a named operator rather than "US/EU cloud", you get that here.
Nutrition in the same API
Terra covers the burn side. If you need intake as well you integrate a second nutrition vendor and reconcile two user models. WearLink ships photo-based meal logging and a calories-in vs calories-out endpoint against the same user record.
Regional food recognition
Most nutrition vision is trained on US-centric food databases and struggles with a thali or a masala dosa. Ours is curated for Indian and South Asian dishes alongside Western ones.
