Why Sleep Cycles Matter for Success

Your sleep moves through 90-minute cycles alternating between light sleep, deep sleep, and REM sleep. Waking mid-cycle leaves you groggy. By aligning wake-up with cycle completion, you wake refreshed with better cognitive function, mood, and energy.


Use the Work Timer to maintain focus during the day. The timer uses the same alarm system to keep you on schedule.


Track your highest game score — it remains until you reset, challenging you to beat your personal best while waiting to fall asleep.
