Show HN: Aidlab – Health Data for Devs

Summary

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, bodyweight reps, body position, and 20 high-level stats like stress or readiness through the API.The most common questions I got are:1) "how is it better than my smartwatch?"2) "why we built it?"Chest-mounted wearables are considered the gold standard for physiological measurements. For example, whenever Apple validates their watch, they benchmark against chest straps [2], as some signals can only be reliably measured (or measured at all!) near the heart including continuous ECG, true respiration (based on lung volume changes) or body position/orientation.As for the second question: the problem for us was that smartwatches were too simple and the data too inaccurate, while advanced medical devices were too pricey or too complicated. We found a sweet spot between accuracy and accessibility - Aidlab delivers medical-grade signals without the hospital-level complexity. As "medical-grade" is a bold statement, we’ve published validation papers comparing Aidlab’s performance with other certified medical devices [3].Today Aidlab is already a pretty mature concept. We've been building Aidlab for 2 years, shipped our first version in 2020, we got our first clients, including Bryan Johnson from Kernel/Blueprint (longevity research) or Boeing/Jeppesen (monitoring pilots’ bio-signals during tests&training).Now we're about to release Aidlab 2 [4] - with additional signals like EDA and GPS, and a bun...
