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.
Choose a topic, put your phone aside and let the audio ease you into sleep. The session ends on time and the voices fade out gently. No endless autoplay and no reason to touch the screen again.
Lock it in after waking.

Optimization without the burnout.
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.
