The problem

Sleep apps are part of the problem.

Counting hours doesn't help you sleep. Tracking REM doesn't make you rest. We built Solstice differently.

i.

Most apps make you anxious about sleep.

Endless graphs, scores, streaks. You wake up to a notification telling you you slept "poorly" — which makes the next night worse.

ii.

Generic advice doesn't work.

"Sleep at 10 PM. Avoid blue light." Your life isn't a textbook. Your sleep needs to fit your reality, not someone else's spreadsheet.

Features

Built around your night
not against it.

Everything Solstice does is in service of one goal: helping you rest, without making you anxious about it.

Adaptive wind-down

Solstice learns the rituals that work for you — and gently nudges you toward them, 30 minutes before your ideal bedtime.

Soundscapes that listen back

Adaptive audio that responds to your breathing, heart rate and movement. No looping rain that wakes you up.

Smart wake window

Wakes you in the lightest 20 minutes of your sleep cycle. You'll never feel jolted out of a dream again.

How it works

Three nights. You'll feel it.

Solstice doesn't ask for setup. It learns as you sleep.

i.

Night one — listen

Place your phone face-down beside the bed. Solstice records ambient breathing and movement. No wearables needed.

ii.

Night two — learn

Solstice builds your unique sleep signature. It already knows when you typically rest deepest, and where you fall short.

iii.

Night three — adjust

Solstice now knows you. It begins to suggest small shifts — earlier wind-down, a different soundscape, a softer wake.

What people say

The first sleep app I didn't delete.

★★★★★

"I've tried six different sleep apps. They all made me feel worse about my sleep. Solstice just... works in the background. I sleep better. I don't know how."

"The smart wake is genuinely magic. I wake up before my alarm goes off, gently, every single morning. I haven't felt this rested since university."

MC

★★★★★

"As a parent of two, sleep is the holy grail. Solstice didn't try to fix me — it learned my chaotic schedule and worked around it. Honest tool."

Questions

Things people ask before signing up.

No. Solstice uses your phone's microphone and accelerometer to monitor sleep ambient signals. Just place your phone face-down on the nightstand.

Sleep data is processed on-device by default. Nothing leaves your phone unless you explicitly opt into cloud sync. We're a small team in Berlin and we don't sell data.

Solstice uses about 2–4% of your battery overnight, depending on your phone. Significantly less than most fitness trackers' apps.

Yes. One tap from inside the app. We don't bury cancellation behind support emails. The trial cancels itself if you don't decide.
