Adrift: DSPD & Non-24 Sleep

WristVault LLC

About this app

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, no spreadsheets, no manual entry 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.

KNOW YOUR ENERGY BEFORE THE DAY STARTS
Daily energy scores and a 14 day forecast help you plan when you will feel your best, and when to go easy on yourself.

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 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 rolling energy forecast with people close to you through your calendar, and they see your general state, 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.

What’s new

The battery learns your week's shape, whatever shape that is. When one day of your week repeatedly runs shorter or longer than the rest, the battery compares that day with its own kind: a Tuesday against your recent Tuesdays. Works for any weekly pattern, switches on only when your own records show it clearly, and Patterns names what it sees in plain words. Plus a quiet optional note when tomorrow morning looks open in your Plan.
