# Sleep Cycle

Smart alarm and sleep tracker that analyzes sleep sounds and wakes you in a light sleep phase.

Sleep Cycle uses sound analysis (or motion) to estimate sleep phases and wakes you during lighter sleep within a chosen window. Premium adds snore and sleep-talk detection, long-term trends and coaching content. Useful for building a sleep diary before a sleep study, though it does not diagnose sleep disorders.

Price: Free; Premium subscription available. Site: https://sleepcycle.com/.
