What the beta can show you
A quick tour of the main screens. The app is still evolving, but these are the ideas we are building around.

Your Day at a Glance
One place for your fatigue snapshot, recent check-ins, and whether your watch has synced. The day brief is there to help you orient, not to score you.
Summary of how you have rated fatigue and what your watch recorded
Shortcuts to pacing and pattern views
Gentle prompts for morning and evening check-ins if you want them

Forecasts from your own history
A view of what might come next based on your past days and today’s data. If it feels wrong, you can say so and keep logging.
Morning and evening views so the horizon matches the time of day
Short explanations of what the app is leaning on
Tap to agree or disagree so the app can learn from you

Activity pacing
Ideas for steps and active time drawn from your recent days, with rest built in. You decide what to follow.
Targets that update as your data grows
Optional rest nudges you can ignore
A simple way to see how a day lines up with what you planned

Your profile
Your usual sleep, movement, and heart signals on this device, so “today” is easier to read against your own normal.
Baselines that firm up as you wear the watch
A clear read on today versus your recent typical
Updates automatically when new data comes in

Daily check-ins
Quick ratings for how fatigue feels, plus an optional evening look back. The more honest you are, the more the app reflects you.
Straightforward sliders
Evening wrap-up when you want it
Space to note things like illness, stress, or PEM

Notifications
Reminders only if you want them, with quiet hours so nights stay quiet.
Turn categories on or off
Overnight quiet by default
Cool-downs so the app does not nag

Research add-ons
Some studies ask for extra logging, for example VNS sessions. You only see this if your study uses it.
Log sessions in a few taps when required
See how sessions sit next to your fatigue and heart data
Framed clearly inside the app when it applies
