Hey Product Hunt 👋

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.

Comment highlights

My partner uses Whoop and I use Apple Watch and we've argued more than once about whose recovery score methodology makes more sense 🤔🧐 genuinely excited something like this exists now 😃

Spent some time in the repo before commenting – looks like the data model is actively evolving, which makes the question I had even more relevant. The docs frame ingestion as either Cloud-based (OAuth provider) or SDK-based. Is there a planned third pattern for sources that fit neither – e.g. a desktop client generating data locally and POSTing records via the public API directly? Technically nothing seems to block it, but curious whether that's intended usage or off-pattern.

Have a project sitting in this exact gap, so watching with interest. Aware it's early-stage.

Congrats on shipping 🚀

self-hosted + MIT for wearable infra is the real gap — most teams glue oura/whoop/garmin together and end up maintaining a janky data lake nobody owns. on the open scoring side, are the algorithms research-grade (validated hrv, recovery, etc.) or more heuristic baselines? and for LLM context: do you ship structured schemas for sleep/strain/activity so an agent can reason directly, or is shaping the context still on the developer?

Open infrastructure here feels overdue— health-data integrations across Whoop/ Oura, apple health…have been such a fragmented mess for builders. What’s the long-term plan for keeping up with the constantly shifting Oauth scopes and rate-limit policies on the closed ecosystems you’re plugging into? Congrats on shipping this!

Saw this shared in a Slack community I'm in and had to come check it out. The combination of open algorithms and self-hosted is a pretty specific bet on where health data is going.

This is great! Next thing we need is standardized API that the vendors commit to adopting. The Bluetooth heartrate profile and Generic Health Sensor profiles were a promising start but haven't lived up to their potential.

How scalable is this if someone is pulling data from thousands of users simultaneously?

Thanks for sharing, that'll definitely unlock the industry!
I've been working on Heart Rate calculations based on raw ppg data. Does your open infrastructure include the data processing for this? I figured these are highly protected IPs by the health tech companies...

I have checked alternatives tab here and as far as I could agree on Terra, most of those products don't seem to be in the same category. Do you know any other alternatives to Open Wearables?

Quick one: can you use this with just Apple Health data from an iPhone, no additional wearable required?

Voted and bookmarked. We're a small product studio in Krakow and this goes on the "evaluate for our next health client" list immediately. The Momentum team has been doing solid work in this space for a while now.

Hello, I’m from Iran. Here, we face many challenges with filtered and controlled internet—especially when it comes to collecting and transmitting data. I wanted to ask how we could collaborate on a wearable gadget that we are currently launching.

Is there a non-developer way to use this, or is it strictly for people who can set up their own server? Asking as someone who trains endurance athletes and wants smarter recovery data without hiring an engineer.

so cool! MCP is a huge unlock for the millions of people also using chatgpt/claude

Another trivia - original name of the project was Healthion ;) I'm curious. Which one do you guys like more?

I’ve previously built and sold a company using wearable data to predict drug relapses and then sought to build a better infrastructure layer for wearable data similar to how Stripe changed the world for fintech.

I didn’t do it nearly as well as Open Wearables has done it. Absolutely huge kudos to the team behind this — super excited to see it grow.

Who hunted Open Wearables?

Open Wearables was hunted by Rohan Chaubey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
