THE DIFFERENCE
A tracker tells you about last night.
EMBER tells you what to do tonight.
Built around your real life
One plan. Four signals.
Zero guesswork.
Every recommendation has a reason. Ember quietly brings together the signals that shape your night, then gives you the next useful step.

Apple Health
Learns from your real sleep — without asking you to log it.
Your overnight data stays on your device. Ember reads what it needs and never writes to Health.Tonight, made simple
A plan you can follow half-asleep.
Ember turns the science into a small sequence of well-timed actions. No spreadsheet. No sleep math at 10 p.m.
9:45Start warmingA short foot bath or warm towel begins the thermal cue.
10:20Dim and downshiftEmber clears the last ten minutes for a quieter landing.
10:30Lights outYour sleep window starts. The alarm is already set.
The Rest Lab
Evidence in.
Better nights out.
Ember is built around two proven levers for better rest: steady sleep timing and a well-timed drop in core body temperature.
PROTOCOL 01
Sleep Window Training
A practical, adaptive take on CBT-I sleep efficiency. Ember starts with a realistic window and widens it as your sleep becomes more solid.

Thermal Wind-Down
