@ClementDelangue We recently added a short instruction for agents that at least helps catch people who won't even bother to glance at the PR their agent created 🥞

[Piotr Sędzik @SedzikPiotr]

@TheBlueBoxDev Thank you so much for contributing to OW!

[Regalos Digitales @RegalosDigitals]

🔥 SANTA MIERDA de iA para bio Hackers desbloqueado para gym bros, Conectá todo y dejá que tu IA te arme el plan de recuperación perfecto.

Repo: https://t.co/RHVKkAP9vR

Guarda esto, a ver quién lo deploya primero👇

[Open Wearables @openwearablesio]

0 → 680 ⭐️ in 4 months.

Developers don't star repos out of politeness.
Every star is someone saying: this solves a real problem.

Open Wearables is an open-source health intelligence platform. One API for wearable data from 300+ devices - Garmin, Whoop, Apple Health, Polar and more. On top of that: an AI reasoning engine with MCP support that turns raw numbers into actual insights.

Self-hosted. MIT licensed. Zero per-user fees.

If you're building in health tech or working with wearable data - take a look. And if you see the value, a star helps the project reach the people who need it:

@andreujuanc @ErickSky We’re going there. Stay strong brother 💪

[Erick @ErickSky]

Alguien acaba de perder absolutamente la cabeza al LIBERAR EL SANTO GRIAL DE LOS GYM BROS

Open Wearables es el backend open-source self-hosted que une Garmin + Polar + Suunto + Whoop + Apple Health en UNA SOLA API normalizada, lista para que tu agente IA (Claude, ClawdBot, el que uses) la consuma directo.

- Instalación en minutos con Docker + Developer Portal Dashboard funcionando (usuarios, API keys, sincronizaciones y métricas de sueño/workouts en vivo).

- Cómo conectar todo y alimentar IA en tiempo real.

- Y lo mejor: ya lanzaron el Flutter SDK + Example App completo para Apple Health (con background sync, permisos HealthKit y demo lista para probar).

Todo local, sin fees por usuario, sin nubes ajenas.

Esto es exactamente lo que necesitas para armar tu propio coach de recuperación, alertas de HRV o dashboards personales con datos reales.

REPOOOO 👇

@ErickSky Thanks for mentioning!!

Gdy na początku lipca 2025 mówiłem "że istnieje realne zagrożenie, iż "wyparuje/zniknie" 25% zawodów w dwa lata - to "mądre głowy" pisały bym się "puknął w czoło" bo się "nie znam na materii" i "bym się zajął noszeniem paczek"🤪
Nie minął rok od tamtej wypowiedzi - no więc Ci którzy są najbliżej materii Ai głośno mówią o nawet 50%:)Myślę, że nie aż tyle, ale te 25% może się okazać bardzo bardzo realne...
Od 10 dni używam wyłącznie ClaudeCode, po 5 dniach pokazałem efekty swoim Top100 managerom, w dwa dni po tym, przestawiliśmy całą firmę na to narzędzie, a ludzie ścigają się w prezentacji zastosowań. Zobaczymy cofam przyniosą kolejne miesiące:)

[Jan Kamiński @jankaminski94]

Wearables have been lying to half their users for years.
Not intentionally.

But algorithms built on data where only 34% of study participants were women will do that.

Oura just launched a proprietary AI model built entirely for women's health.

Here's what it signals about where the industry is going 🧵

[Jordan Carlisle @jordantcarlisle]

Been thinking about this non-stop. The first prototype I Claude Codes was with Open Wearables, which resulted in a product that took me over a year to build in the last with less capability and integration.

I also can't help but think how we need decentralized data storage now more than ever.

[Open Wearables @openwearablesio]

We're not doing the typical "launch on Product Hunt and pray" strategy.

Instead: test positioning across platforms, learn what resonates, build real momentum.

Last month: #3 on Peerlist.

Today: Micro Launch.
Next: DevHunt.
Then: Product Hunt.

Open Wearables - unified API for 200+ wearables. Self-hosted, MIT license.

Every launch teaches us something before we go live on Product Hunt.

400+ stars on GitHub.

Open Wearables is an open-source platform that connects 200+ wearables through one unified API.

Actively developing. Latest release: 0.3.0-alpha https://t.co/BS6wFX1BK0
