Solstice listens to your night, learns your patterns, and gently nudges you toward better rest. No alarms that scream. No spreadsheets to fill.
Counting hours doesn't help you sleep. Tracking REM doesn't make you rest. We built Solstice differently.
Endless graphs, scores, streaks. You wake up to a notification telling you you slept "poorly" — which makes the next night worse.
"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.
Everything Solstice does is in service of one goal: helping you rest, without making you anxious about it.
Solstice learns the rituals that work for you — and gently nudges you toward them, 30 minutes before your ideal bedtime.
Adaptive audio that responds to your breathing, heart rate and movement. No looping rain that wakes you up.
Wakes you in the lightest 20 minutes of your sleep cycle. You'll never feel jolted out of a dream again.
Solstice doesn't ask for setup. It learns as you sleep.
Place your phone face-down beside the bed. Solstice records ambient breathing and movement. No wearables needed.
Solstice builds your unique sleep signature. It already knows when you typically rest deepest, and where you fall short.
Solstice now knows you. It begins to suggest small shifts — earlier wind-down, a different soundscape, a softer wake.
"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."
"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."

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