Every source, one tap
Oura. Apple Health. Peloton. Garmin. Connect once. We handle the rest in the background. You never screenshot anything.
Meld · Pre-launch
Your health,
synthesized.
Meld quietly connects every signal from your body — sleep, workouts, food, recovery — and tells you what matters, what it means, and what to do next.
Built by Brock Howard · 15+ years in consumer health
The problem
Your data is already everywhere. Nowhere is it actually useful.
Your sleep ring knows your deep sleep minutes. Your workout app knows your heart rate zones. Your food log lives in a third place. Your doctor has your labs.
None of them talk to each other. Every app shows you its own slice and leaves you to connect the dots.
That's not a coaching problem. That's a data problem.
What Meld does
Meld connects it all. Then it coaches you.
One view that makes sense
Sleep, training, nutrition, recovery — all in one context. Not twelve dashboards. One coach that sees everything at once.
Answers, not dashboards
Ask anything about your health. Get clear, specific answers. Not charts. Not jargon. Actual advice.
Smarter every week
Meld learns your body. What works for you. What doesn't. The longer you use it, the better it gets at coaching you specifically.
How it works
Four steps. Nothing to configure.
-
Connect your sources
Tap to link Oura, Apple Health, Peloton, Garmin, and more. We read only what you authorize. You can disconnect any source in one tap.
-
We sync in the background
Meld pulls your latest data every few hours. Sleep, workouts, steps, heart rate, HRV, food. No screenshots. No manual input.
-
Your coach reaches out
When something matters — a big recovery dip, a pattern across meals, a workout suggestion — your coach tells you. When you have a question, just ask.
-
You get smarter over time
Meld discovers real patterns in your data: sleep vs nutrition, recovery vs training, HRV vs stress. It tests them statistically and only surfaces what holds up. The longer you use it, the sharper it gets.

Grounded in research
Every claim cites the study behind it.
AI is easy. Honest AI is harder.
Meld's coach is trained to ground its advice in published research, not in vibes. When Meld says "your deep sleep improves when you eat more protein at lunch," it links the actual paper that shows why.
You can click the citation. Read the study. Trust your own judgment.
Under the hood
Not just AI. Real statistics.
Most AI health apps read your data and guess. Meld runs actual statistical tests.
30 days of your data
Meld collects sleep, food, workouts, HR, HRV, and recovery from every source you connect. After 30 days it has enough signal to start looking for patterns.
Test every pair
Protein vs deep sleep. Workout intensity vs next-day HRV. Dinner timing vs sleep onset. Meld tests correlations across every domain, not just the obvious ones.
Control for false discovery
With dozens of metric pairs, some will look correlated by chance. Meld applies false-discovery correction so you only see patterns that hold up statistically, not lucky noise.
Validate against research
If a pattern survives statistical testing, Meld checks it against published studies. You see the finding AND the paper behind it. Not a hunch. Not a hallucination.
413 automated tests verify this pipeline before every release. The coach only tells you what the numbers actually show.
Connects to the apps you already use.
- Oura Sleep, HRV, recovery
- Apple Health Activity, heart, body
- Peloton Workouts, rides, runs
- Garmin Steps, HR, stress
- + more Eight Sleep, Whoop, CGMs coming

Your data, yours
Health data deserves a higher bar.

- Literature-grounded AI can be wrong. We link every claim.
Why I'm building this
Last year, I was screenshotting six health apps into ChatGPT every morning to get advice. It worked — better than any single app. But the friction was ridiculous.
Meld is what I wanted to exist. I'm building it for myself first. If it works for you too, I'd love to hear about it.

Questions
Things people ask before signing up
-
When does Meld launch?
Meld is in active build. The iOS app is close. Waitlist members get access first. We'll email you the week we open up early access. -
Is it iOS only?
At launch, yes. iPhone first. Android and web will come later, after we've made iOS great. -
How much will it cost?
Meld will have a free tier and a paid subscription for deeper coaching and history. Pricing is not finalized. Waitlist members will get a founder's rate we won't offer again. -
What data sources work today?
Oura, Apple Health, Peloton, and Garmin are connected in the app today. More sources — Eight Sleep, Whoop, continuous glucose monitors, electronic health records — are coming. -
Can I use Meld without a wearable?
You can get value with just Apple Health and food logging, but the coach is dramatically better when it has sleep, HRV, and recovery data from a ring or watch. -
Is Meld HIPAA compliant?
Meld is a consumer wellness app, not a HIPAA covered entity. We still treat your data with the same seriousness HIPAA requires. Encryption, access controls, audit logs, minimum necessary access. Full details in our Privacy Policy. -
Can I delete my data?
Any time. Inside the app or by emailing [email protected]. We comply within 30 days. -
How is this different from Oura, Whoop, or ChatGPT?
Oura and Whoop are excellent at one thing each, but neither sees across domains. ChatGPT knows nothing about your body until you feed it screenshots. Meld connects every source, runs real statistical tests on the data, controls for false discovery, and only surfaces patterns that actually hold up. Then it coaches you on the one that matters most today.
