Shift your sleep
What's different?
Learn how you respond to various shift patterns, and how you can best recover.
Wake to gentle vibrations instead of jarring alarms—no sound, no partner waking up.
Somna detects your lightest sleep phase and triggers your alarm at the perfect moment.
Import your work roster and Somna calculates optimal sleep windows automatically.
Over one week, the system learns your sleep patterns and fine-tunes wake predictions.
No complicated config—just create an account and let Somna handle the rest.
