PowNap vs Flow

PowNap helps you wake up at the right moment by tracking your recovery. Instead of forcing you awake with a random timer, PowNap watches your heart rate and wakes you when your body feels ready. Less grogginess. Less guessing. Better naps. Power Nap Choose: 15 min 20 min 25 min PowNap may wake you earlier if your body recovers faster. If not, your selected duration remains the maximum limit. Infinity Nap No fixed timer. PowNap monitors your recovery and wakes you when your body appears ready. Perfect when you want rest without watching the clock. How it works Start your nap.
