WearLink vs Junction (formerly Vital)
Healthcare infrastructure combining wearable data with nationwide lab-test ordering in one API.
Junction, previously Vital, repositioned from pure wearable aggregation into broader healthcare infrastructure by bundling lab testing. It connects wearables and medical devices and also lets you order lab tests across all 50 US states through partners including LabCorp and Quest, then returns the results through the same API. It raised an $18M Series A in 2025.
That makes Junction a different kind of product from WearLink rather than a straight competitor. If your roadmap includes ordering blood panels, Junction does something we do not do at all and have no plan to do.
Where the two overlap is the wearable layer, and where they diverge most sharply is geography. Junction's lab network is US-based. For a product serving Indian users, the lab half of the value proposition does not apply, and the data-residency question runs the other way.

| Geography | US-centric; lab network is US-only | Asia-Pacific hosted, with global provider coverage |
| Nutrition | Not a core capability | Photo meal recognition tuned for Indian and Western food |
| Pricing | Quote-based | Published flat tiers from free to $399/mo |
| Funding and scale | $18M Series A, established team | Early-stage |
When Junction (formerly Vital) is the better choice
If you need lab testing, Junction wins outright
We do not order blood panels and will not. For a US diagnostics or virtual-care product where labs are core, this is not a close call.
Larger device catalogue
300+ devices against our 14.
Better funded and further along
An $18M Series A buys engineering capacity and staying power. That is a legitimate factor when you are picking infrastructure you intend to depend on for years.
Where WearLink is the better fit
Relevant outside the US
Junction's lab network stops at the US border. If your users are in India or elsewhere in South Asia, a large part of what you would pay for is unusable.
Nutrition rather than labs
For consumer metabolic-health products, daily intake data is often the more actionable signal than a quarterly blood panel — and it is the half most wearable APIs leave out.
Published pricing
Junction is quote-based. Our tiers are on the pricing page.
