Where did your energy go today? Which moments quietly drained you, and which ones — even small ones — actually brought you back? You can guess. Or you can run a Self-Discovery experiment and watch your body answer in real time, on real data, on a piece of your own life small enough to remember.
Learning to spot how your body actually responds to the things you do is a real skill — and one of the most useful ones for a happier, more energetic life. A Self-Discovery experiment is how you start building it.
What an experiment is
For a short stretch of your day, you wear your Apple Watch and live your life. Then have a meeting. Go for a walk or a run. Drive somewhere. Make dinner. Argue with someone. Take a nap. Do nothing.
Welltory tracks every minute of it — your heart rate, your stress, your activity, your energy — and then walks you through what happened, piece by piece. You finish with a clearer answer to the question your body has been trying to tell you all along: what's actually draining me, and what's bringing me back?
It's the fastest way to learn how to read your own data — on a slice of your life small enough to remember in detail.
How to run one
It's three simple steps:
1. Start an experiment. Open your app and tap the experiment block. Before your first experiment it sits at the top of Today; after that, you'll find it lower down, under your insights.
2. Pick how long you want to watch. You can choose 1, 1.5, 2, or 3 hours. Two hours is the recommended length — long enough for something interesting to happen, short enough to remember in detail.
3. Live your life. Wear your Apple Watch and go about your day — a meeting, a walk, a workout, an errand, a quiet evening. Welltory tracks everything in the background. A progress bar on your Today screen and lock screen shows how much time is left. When the experiment is done, we'll send you a push.
A few things worth knowing:
Keep your Apple Watch on the whole time. If you take it off or it runs out of battery, we lose the data.
It runs in real time. A 2-hour experiment takes 2 actual hours. You can't fast-forward it.
Pick a stretch you'll be able to remember. The whole point is to connect what your body did to what was happening in your life — so anything you'll recall later in detail is a good candidate.
When the time is up and we've received all the data from your Apple Watch, you'll get a push notification.
What you get in the result
You'll see a breakdown of the period you just lived through — how everything you did affected your stress and your energy. Where your strength went, what brought it back, how movement, conversations, lying around, and anything else in between shaped how your body felt. The whole picture, minute by minute.
The point isn't just to look at this one experiment — it's to teach you how to use the daily timeline tool that paid Welltory users have access to every day, inside the stress and battery reports. Once you've read your data on a small slice you remember in detail, the same view starts making sense for any other day.

When to use it
There's no wrong moment. But experiments are especially worth running when:
Something specific is coming up and you want to see how your body handles it — a hard meeting, a workout, a call you've been dreading.
You want to check whether something that feels relaxing actually relaxes you — a walk, a coffee break, ten minutes of scrolling.
You're curious about a normal stretch of your day — the morning routine, the after-work wind-down — and want to see what's really going on under the surface.
You want to learn the app on a small, memorable piece of your life before reading bigger reports.
Open Welltory, pick two hours of your life, and let your body show you what you've been missing.
