Adrift: DSPD & Non-24 Sleep

Adrift is the sleep companion built for a body clock that runs late or drifts around the clock. It connects straight to your wearable through Health Connect, so your sleep flows in automatically. No file uploads or spreadsheets to keep up with.

Most trackers stop at a chart. Adrift keeps going.

PLAN AROUND THE DAY THAT MATTERS
Pick a day you cannot miss, a shift, an appointment, a flight, and your personal Playbook ranks real strategies to be awake and alert for it. Every option comes with the tradeoffs spelled out plainly, so you choose with your eyes open instead of guessing.

SEE THE PATTERN, NOT THE CHAOS
Your sleep timing is laid out on a double-plotted actogram, the same chart sleep researchers use, taught here in plain language with a guide on how to read it. Watch your drift emerge, measure how fast your rhythm is moving, and get a forecast of when sleep is likely to realign with daytime.

SEE WHERE YOUR TIMING IS GOING
Your last nine nights, one row each, with the middle of each night marked. A schedule holding steady draws a straight column, however late it sits. A schedule on the move draws a staircase. No score, no grade, and nothing you can fail.

A REPORT YOUR DOCTOR CAN READ
Export a clean, doctor-ready summary of your patterns for your next visit, without handing your raw data to anyone.

BUILT FOR LATE AND DRIFTING SLEEP
Adrift is made for Delayed Sleep Phase Disorder (DSPD, also called DSPS or DSWPD) and Non-24-Hour Sleep-Wake Disorder (Non-24). Whether you are newly diagnosed, exploring accommodations, or just trying to make life work with a rhythm that does not match the 9 to 5 world, Adrift meets you where your clock actually is.

EASY ON YOUR EYES AT 3 AM
A warm, low-blue interface with a true red night mode, because a sleep app should not glow blue at you in the dark.

PRIVATE BY DESIGN
Your sleep data stays on your device. No account, no cloud sync, no ads. Import sleep automatically from Health Connect or enter it by hand. Share a tentative rest window with people close to you through your calendar, so they can plan around a tentative rest window. They see a planning window, never your health data.

Adrift is free, with no feature locks and no ads, ever. If it helps you and you want to support development, there is a one time supporter unlock.
