The problem
Wearables cost $200–$400 and still can’t tell you why you slept badly
Sleep apps track duration but ignore the habits that actually matter
You know caffeine affects sleep — but do you know your personal cutoff time?
OutLast connects your daily habits \u2014 meals, caffeine, exercise, screen time \u2014 to your sleep patterns. No hardware required.
How it works
Use the bedtime-to-wake slider to log sleep in seconds. No manual math, no typing timestamps. Just slide and save.
Log meals, caffeine, workouts, and other habits throughout the day. OutLast timestamps everything so you can see the connections.
Late dinners tanking your sleep quality? Afternoon caffeine pushing your bedtime? Your data tells the story — OutLast makes it visible.
What you get
Log bedtime and wake time manually with a simple slider. Accurate, fast, and free — no charging another device.

The science
What people say
“I discovered my 2 PM coffee was pushing my sleep onset back by 45 minutes every night. Cut it out and I’m falling asleep in 10 minutes now.”
“I used to blame stress for my bad sleep. Turns out it was eating dinner at 9 PM. OutLast made the pattern obvious within two weeks.”
“Sold my Oura Ring after a month with OutLast. The wearable told me I slept badly — OutLast actually showed me why.”
