Build personalized health products with one API for every wearable. Access wearable data, open health scoring algorithms, and structured context your AI can reason with. Self-hosted, open-source, MIT licensed.
Every team building with wearable data rebuilds the same infrastructure. Oura, Garmin, Whoop, Apple Health: each with its own API, its own schema, its own quirks. Weeks of plumbing before you get to the product itself. And even once the data is flowing, you still have to turn it into something a user or a clinician can act on.
We've lived this at Momentum for years, shipping healthtech for digital health, wellness, and clinical teams. So we put the whole stack in the open.
Meet Open Wearables: the health intelligence platform for wearable data. One open-source layer to ingest from any wearable, standardize the signals, score them with transparent logic, and let AI reason over what's actually happening in a user's body.
Here's what Open Wearables gives you:
📡 Unified wearables API , ingest from Oura, Garmin, Whoop, Apple Health, Polar, Suunto, Samsung, Strava, Google Health Connect
🧬 Data standardization , one consistent schema across every device, so you stop writing per-vendor normalization code
🧮 Open health scoring logic, auditable, forkable, tuneable for your domain. No proprietary black boxes.
🎯 Coaching profiles, domain-specific intelligence layers for wellness, clinical, and performance use cases
🤖 MCP server, any LLM can reason over health trends and patterns, not just read raw numbers
🔒 Self-hosted by design, MIT license, HIPAA and GDPR friendly
💸 $0 per user at any scale, no per-seat pricing, no surprise bills at 10k users
Open Wearables is already running in production inside healthcare and wellness apps, including teams building AI coaching products on top of it.
What makes Open Wearables different?
Other wearable APIs stop at raw data delivery. Open Wearables is a full health intelligence layer: data in, meaningful signals and AI-ready context out. Open algorithms, zero per-user fees, and an AI-native architecture from day one. Built by Momentum, 130+ engineers with 10+ years of shipping healthtech in regulated industries.

Open source health scoring algorithms is the part that got my attention. Most of these platforms treat the scoring logic as the crown jewels. Who decides what goes into the scoring models?
Three people in my Slack have tagged me in this today. The health data fragmentation problem is real and annoying, and the open-source angle means it might actually last longer than a VC-funded API startup.
Am I seeing this right? Its opensource?
Where would I be paying?
Great launch, team! This is super interesting, especially the “one API for wearables” angle. How many devices are supported today?
Congratulations on the launch! Your unified health data model is what interests me the most, but I'm worried about datatype proliferation/complexity if I build something downstream of OpenWearables (e.g. your wide table for WorkoutDetails). I really appreciate that I would have the same problem if any given wearable provider made changes to their schema, but what are your plans for keeping your data model in sync with providers without causing other developers headaches?
Showed this to a founder friend building a longevity tracking app. She said the API coverage alone would have saved them six months of backend work. Congrats Momentum, timing on this feels right.
I share screenshots of my Whoop app with claude currently and ask it to analyse it based on the screenshot. Let me try using the MCP and ask it, feels like that could be a much smoother experience
Free, self-hosted, MIT license. Those three together in a health data tool is rare enough that I had to double-check the page. What's the long-term monetization plan, just curious?
Plugged this into our club management app. Coaches finally see readiness, sleep, and load across every athlete - regardless of which device they wear. Stops the screenshot chase.
Congrats on the launch!! Is there something like a web dashboard for regular users, or is this purely for developers building things on top?
Slightly skeptical question: how stable is the Garmin and Oura API access? Those platforms have changed or restricted third-party access before. What happens to a self-hosted deployment if an upstream provider breaks the connection?
So cool for businesses!
Do you plan to release / or have something for regular users, who don't know how to use open source ? :D I mean, I would love to audit my apple health workouts and get some feedback our of it.
Does this require running your own server infrastructure to be useful, or is there a path for someone who just wants to connect their Garmin and start pulling data without a DevOps background?
I wear an Oura ring and have always been curious how the readiness score actually gets calculated. The fact that you can actually look at the algorithm here seems like it could change how much I trust the number. Do you publish explanations alongside the code?
Voted. Curious whether the MCP server part is something an average person could set up with ChatGPT or Claude, or if that requires serious technical knowledge. The idea of asking an AI questions about your own health data sounds more useful than any wearable dashboard I've seen.
Congratulations to the team! Are the health scoring algorithms customizable or are they fixed out of the box?
Been on Apple Watch + Bevel for ages and still feel like I'm only using maybe 20% of what my data could actually tell me... definitely the right move. Love the open source approach, too!
Also full disclosure — I know the team behind this and they don't ship things halfway. Congrats guys, lfg!
What a geat product! I am using multiple different health techs myslef (garmin, Oura, apple) and was missing solution like that. Been following news from Open Wearables on Linkedin for some time and I'm happy to see this launch!
