I wear a WHOOP. I've coached people on movement and sleep for many years and I still can't answer that question for myself. The algorithm is locked. You get a number, you trust it, you stop there.
When we built Open Wearables, we decided the scoring layer should work differently. Sleep Score and Resilience Score shipped in v0.5 - every coefficient, every threshold, every weighting is in the repo and you can fork them, tune for endurance athletes or elder care or clinical populations. Moreover, you run them on your own infrastructure and the same algorithms feed the MCP layer so AI coaching can cite the actual data behind a recommendation instead of approximating.

@istiakahmad Thanks Istiak, appreciate it. The healthtech space especially needs more open infra: too much critical patient data sitting behind closed APIs and per-user fees.
@istiakahmad Yeah, open source with the great care for software quality is what we really need in the age of AI.
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.
Do they have an explainer video already or not?

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

@kohnigel Thanks Nigel! That's the bet, the moment "ask Claude about my sleep last week" becomes one click instead of a CSV export, the whole consumer health workflow shifts. MCP is the entry point, but the real unlock is agentic: long-running assistants that watch your trends, flag anomalies, and reason across weeks of data without you prompting. Still early days, but the direction feels right.

@piotr_ratkowski makes sense - great example: personalized recipes drafted based on blood glucose levels
@kohnigel Indeed, but rememember - at the moment our MCP is still not 100% production ready.
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!

@zuzanna_gutkowska Do you have your favourite Open Wearables linkdin posts series? Just curious which ones reached you ;)

Nice work! The developer-first approach really shows in how you’re describing the product.

@syed_shayanur_rahman Thanks. Developer-first was a deliberate call: if the foundation isn't solid and transparent, everything built on top is fragile.
@syed_shayanur_rahman That's an honor to hear that, thanks!
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 😃
