Metrya
Your Apple Health data, actually explained
I use an Ultrahuman ring, Omron BP monitor, a smart scale, and a few other trackers - everything flows into Apple Health. Hundreds of data points every day. But when I wanted to actually ask questions about my data - trends, correlations, what's off - there was nothing on iOS that didn't come with a subscription and a third-party server sitting between me and my health data.
As a developer, I know how easy it is to export HealthKit data and run it through an AI model directly. So I got frustrated and built exactly that.
Metrya reads your data straight from HealthKit and lets you connect your own API key - Claude, OpenAI or Google. Your data never touches my servers. A single $10 API credit realistically lasts 6+ months of daily use. No subscription, no middleman, no "premium insights" paywalled behind a monthly fee.
I built it mostly for myself, and I use it every day - which means I keep adding features. Next up within a week: AI-proposed smart goals and streaks, plus more biohacker-oriented analytics.
If you're into health tracking, longevity or just hate unnecessary subscriptions - I'd genuinely love your feedback. What would make this more useful for you?

Really interesting problem to solve. I've been working on something similar — Awra also reads from Apple Health and generates weekly AI narratives across sleep, activity, and nutrition to surface cross-domain patterns. One thing I noticed: the privacy angle (no third-party servers) resonates strongly with the QS audience. What's your take on the weekly digest format vs. on-demand queries? We went with weekly synthesis for Awra, but curious if power users want more real-time interaction.
