four steps to
better sleep
simple enough to stick to. effective enough to make your 3 am self genuinely mad.
set your schedule
tell lumi your bedtime, and wake time. it builds your sleep schedule in seconds.
wind down before bed
calming exercises, soundscapes and brain dumps to ease you into sleep.
apps get locked
at bedtime, distracting apps are blocked. emergency unlocks if you really need them.
wake challenges get you up
smart alarm with challenges - math, pushups, walking, barcode scan, and more.
willpower doesn't work
at 2 am
you don't have a sleep problem - you have a phone problem. every scroll delays your rest. lumi removes the decision entirely by locking your distracting apps and guiding you to sleep.
built for real
sleep problems
smart app lock
at bedtime, all apps except calls & messages are blocked with a lock screen until wake time.
wind-down activities
guided breathing, body relaxation, and calming soundscapes to ease you into sleep mode.
brain dump & gratitude
write down racing thoughts and gratitude notes before bed. Review them anytime - stored only on your device.
wake challenges
math problems, emoji memory, walking 30 steps, pushups, jumping jacks, shake phone, barcode scan, and more.
ml-powered verification
uses your camera to verify exercises and confirm you're actually awake. No fooling the alarm.
emergency unlock
customize 1-3 emergency unlocks per night, each lasting 5 minutes. For real emergencies only.
we don't want
your data
everything stays on your phone. your journal, your schedule, your streaks - it's all yours.
100% on-device
all your data - journal entries, schedules, streaks - stays on your phone. nothing is uploaded.
no tracking of your habits
we use analytics only for crash reports and app stability. we never see your sleep data.
no account required
just open the app, set your schedule, subscribe and go. no email, no sign-up, no cloud sync.
sleep smarter, scroll less
