Open Wearables

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.

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.

Hello, can this be used for react natives based on Expo?

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?

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 usersOpen 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.🎁 Exclusive for Product Hunt: book a free 30-min architecture call with the Momentum team that actually built it.
