Most sleep tracking stops at a score. Today reads your sleep debt, moves the meeting that keeps you up, and changes one thing a week until your nights hold.
You already know you slept badly. The hard part is the 8pm call, the 4pm coffee and the Wednesday that pushes bedtime an hour later.
Today measures the gap between the bedtime you meant to keep and the one you kept, then shifts your window in 15-minute steps. It moves the late call, pulls wind-down earlier, and only ever asks for one change at a time.
A running 14-night sleep debt number, and a plan to clear it that fits your calendar — recovery scheduled on the evenings you're free instead of a vague instruction to sleep in on Saturday.
Pulls sleep stages, resting heart rate and HRV from your watch or ring. When recovery is down, Today eases the day: the hard workout moves, the 7am call gets pushed, the wind-down gets protected.
A nudge at the moment it can still change the night — before the second episode, not after. Screens, lights and the last message, handled in the same assistant that runs the rest of your day.
Learns your real cut-off time from your own nights, then holds you to it.
Fixes the wake time first, because that's what moves the bedtime.
A day-by-day shift for light, caffeine and bedtime around travel or a rota.
A clean summary you can hand to a doctor when a pattern deserves one.
Same install — the plan you get depends on the schedule, the wearable and the week Today learns you have.
Every night you plan for 11 and land at 1. Today walks the window back 15 minutes at a time and holds the wake time steady so the shift actually sticks.
Four short nights and a Friday deadline. Today shows the debt, then puts the recovery night where your calendar has room instead of telling you to catch up later.
An 8pm call twice a week is the reason bedtime slips. Today names the cause and offers to move it — the fix lives in your calendar, not in a tip list.
Nights are not yours to control, so Today works on what is: naps, the earliest realistic wind-down, and a lighter day after the worst nights.
Apple Health, Oura or Whoop for the nights; your calendar for the reason they went wrong. Two minutes, once.
Two weeks in, Today knows your usual bedtime drift, your HRV range, your caffeine cut-off and which evenings never go to plan.
A single adjustment, a nudge that arrives in time, and a Sunday recap of what moved — until the schedule holds without you thinking about it.

No, but it helps. With an Apple Watch, Oura or Whoop, Today reads sleep stages, resting heart rate and HRV. Without one it uses your phone's bedtime signals, screen activity, calendar load and a ten-second morning check-in — enough to see the pattern and change it.
Today measures the gap between the bedtime you intended and the one you kept, then changes one variable a week — the last meeting, the caffeine cut-off, evening light, or a 15-minute earlier wind-down. Small shifts you can keep beat a ten-point sleep-hygiene list you can't.
Sleep debt is the running gap between the sleep you need and the sleep you got, usually over the last 14 nights. Today keeps that number visible, then plans recovery into nights that are actually free instead of telling you to catch up on Saturday.
Most sleep trackers hand you a score at 7am and stop. Today owns the follow-through: it moves the 8pm call, nudges wind-down while there is still time to act, protects a recovery day after a heavy week, and drops your late workout when recovery is down.
Yes. Give it the destination or the rota and Today builds a day-by-day shift plan for light, caffeine and bedtime, then adjusts as your real sleep comes in.
No. Today is lifestyle support, not a medical device. It can show a clinician a clean 30-night trend and flag when a pattern deserves a real appointment, but diagnosis and treatment belong to a doctor.
Today reads your sleep debt, names the meeting that keeps you up, and changes one thing a week until your nights hold. Free during the public beta on iPhone, Android, macOS and the web.
