No noisy dashboards or guilt-trip streaks. Just the signal you need to sleep better and spend your energy wisely.
Soluna measures your sleep debt — the gap between the sleep you need and the sleep you actually got — and shows it as one calm number you can act on.
Your signature energy curve forecasts your alertness across the whole day, so you can schedule deep work for your peaks and ease off during the dip.
Soluna suggests the few science-backed habits that actually move the needle on sleep — and nudges you at the right moment, not all at once.
Soluna does the math in the background. You just live your day with a little more foresight.
Link Apple Health or your Apple Watch. No wearable? Soluna can work from a simple sleep schedule too.
It models your sleep pressure and circadian rhythm to find your real sleep need and energy pattern.
Each morning you wake to your energy forecast, a smart bedtime, and a few well-timed nudges.
Soluna's energy curve comes from the two-process model of sleep — the same framework sleep researchers use. Two forces combine into the rhythm you feel every day.
The longer you're awake, the sleepier you get. Rest clears it; sleep debt keeps it high.
Your internal clock drives a morning rise, a post-lunch dip, and an evening second wind.
Soluna finds when your body starts winding down, so your bedtime lands with your biology.
“I finally understand why I crash at 3pm — and what to do about it. The energy curve is weirdly accurate.”
“The smart bedtime alone changed my mornings. It feels less like an app nagging me and more like a calm coach.”
“It's the most beautiful, least stressful health app I've used. I check it every morning before anything else.”
