Hi HN, I made a tool for displaying your Apple Health data (activities, workouts, body metrics) and display them in Grafana to be manipulated, aggregated etc. It's useful for finding trends, get daily/monthly/yearly stats and visualize outdoor routes on a bigger screen !

I kept trying to explain how important outdoor light is and how most people aren’t getting enough. Eventually I figured that showing is more effective than telling. So we built a free app that uses your Apple Watch or iPhone to automatically track your light exposure throughout the day. It tells you if you’re getting enough, shows you how consistent you are, and rewards habits that support hormone balance. It's in beta on TestFlight, let me know what you think!

Hey HN! I'm Jakub, and together with my co-founders Agnieszka and Nathan, we built Aidlab, a wearable that gives developers gold-standard physiological data. Unlike health trackers with locked-down APIs, Aidlab ships with a free SDK [1] across 6+ platforms so you can just pip install aidlabsdk or flutter pub add aidlab_sdk or whatever platform (even Unity), and start streaming raw health data and events in real time with simple didReceive*(timestamp, value) callbacks. Currently, we are exposing 13 data types including raw ECG, cough/snoring, motion, raw respiration, skin temperature,…

Hey HN, I built Pace, a Claude Connector that lets you connect all your wearables (Garmin, Polar, Whoop, 20+) with Claude. You connect your devices once and can analyze your data with Claude. No Dashboard needed, just in natural language. I already use it everyday, especially the visualization tool in Claude makes this really cool to use. Tools include: overview, sleep, training, activity, samples and trends. Tech Stack: Python (FastMCP), Google Cloud Run, Google Cloud SQL (PostgreSQL) and Firebase It is live and free to try (no Claude Pro/MAX Plan needed).. Would love feedback,…

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…
