How it works
Your wearable has been recording your body's signals for months — maybe years. Every heartbeat, every night of sleep, every workout. All of it sitting there, never read as a whole. Here's what happens when it finally is.
Upload what you've got
You export your health data from your wearable's app — Apple Health, Fitbit, Oura Ring, Whoop — and upload it here. If you have an Apple Watch, you export a .zip file from the Health app on your iPhone. If you use Oura or Whoop, you connect with one tap and your data comes through automatically.
Everything your wearable ever recorded gets read: every heart rate reading, every night of sleep, every workout, every step. 1 month of data is enough to produce a useful Revelation. 6 years is enough to change how you think about your body.
Your data stays on your device
When you upload an Apple Health export, the entire file is unpacked in your browser. The raw data — every individual heartbeat, every minute of sleep — never leaves your device. Only daily summaries are stored: your average heart rate for the day, how long you slept, how many steps you took. The raw export stays with you.
What gets read
Get your Revelation
This is the part that changes things.
Your entire history gets analysed — not just today's numbers, but months or years of patterns. The analysis looks across all your metrics at once: how your sleep relates to your training, how your heart rate variability responds to different workout intensities, where your recovery is compromised and why.
The output is your Revelation. Not 20 insights. Not a generic report. One headline, specific to you, that you'll want to screenshot and send to a friend.
“Your spin class is working against you.”
Average workout heart rate 172 bpm — well above the zone where your body burns fat. Weight plateaued for 8 months despite training 5 times a week.
“Your bedtime slipped 70 minutes. Everything else followed.”
You haven't slept before 11pm on a weekday since October. Resting heart rate is 6 bpm higher than it was in summer. Everything traces back to sleep timing.
“80% of your running is in the wrong zone.”
Only 20% of your training time is building endurance. The rest is too hard to recover from, too easy to build speed.
Every Revelation follows the same structure: a headline that surprises you, the evidence from your own data that backs it up, a contrast between what you're doing and what your body is telling you, one clear fix, and what the data suggests will change if you follow it.
Context makes it safe
Before your Revelation is generated, your context gets checked. During onboarding, you answer a few quick questions about your goals, injuries, and lifestyle. These act as guard rails.
If your data shows a beaten-up nervous system from injury recovery, the Revelation won't be “train harder” — it will be “protect your recovery.” The same data, different context, completely different Revelation. That's why context matters more than data alone.
Follow your plan
Your Revelation comes with a fix — one specific change you can make this week. Not 5 things to try. Not a 12-week programme. One thing, the single biggest change based on what your data actually says.
If the Revelation is about overtraining, the fix might be: “Drop to Zone 2 for 4 weeks. Keep your heart rate between 125 and 135 bpm. Walk if you have to.” If it's about sleep timing, the fix might be: “Set a 22:30 alarm. Just that. The data says everything else will follow.”
The fix is always grounded in your numbers and backed by exercise science. No generic advice. No guesswork.
Track it with your Signal
Once you have your Revelation and your plan, you need a way to know if it's working. That's the Signal Score — a single number from 0 to 100 that answers one question: is your body recovering or declining?
A Signal of 78 means things are going well — you're recovering, adapting, sleeping properly. A Signal of 43 means something is off — built-up stress, poor recovery, overtraining, or broken sleep. You don't need to work out why. The score tells you.
The Signal combines 5 inputs from your wearable data: heart rate variability, resting heart rate, sleep quality, training load, and the overall trend direction. It's calibrated to your body — not population averages — so it gets smarter the longer you wear your device.
Check it every morning. Watch the trend over weeks. Line goes up, the plan is working. Line goes down, something needs to change. That's it.
Any wearable. 1 month of data. 5 minutes.
1 month of consistent wearable data is enough to produce a Revelation you can act on. If you've been wearing your Apple Watch, Oura Ring, or Whoop for at least a few weeks, you have enough data right now.
With 3 to 6 months, your Revelation can draw on trends, stress-and-recovery patterns, and how your training load relates to how well your body is adapting. With a year or more, the analysis can spot seasonal patterns, long-term direction, and the kind of deep story that makes the whole thing click.
The longer you've worn it, the sharper your Revelation gets. That's not a marketing line — it's how the maths works.
