The high-performance bedtime loop
Input at night. Energy by morning.
SleepSmarter uses the transition into sleep intelligently: focused input before bed, undisturbed recovery at night and active recall after waking.
Protect the recovery.
The session ends on time, voices fade naturally and the interface disappears. No autoplay spiral and no reason to touch the screen again.
Lock it in after waking.
A two-minute morning recall brings back the core facts while optional sleep signals show whether learning ever came at the cost of rest.

No fake “learning while unconscious”
New material is introduced while you are awake and reinforced after waking. Sleep is protected rather than treated as hidden study time.
No productivity theatre
SleepSmarter measures useful recall and next-day readiness — not time spent, taps made or meaningless activity streaks.
No bedtime rabbit holes
One objective, one session and an automatic ending. The app is designed to disappear before your sleep window begins.
Your biology outranks your ambition
If more input consistently means worse sleep, the smart recommendation is less content — because tomorrow's performance is the actual goal.
