FixSleep – Sleep Cycle Calculator & Relaxing Sounds
Wake up refreshed, not groggy. FixSleep is your smart sleep companion that helps you align with your natural circadian rhythm and wake up at the perfect time — every time.
By tracking the body’s 90-minute sleep cycles, FixSleep suggests the best times to fall asleep and wake up, helping you feel more energized and focused throughout the day. Whether you’re heading to bed now or planning tomorrow’s routine, FixSleep gives you science-backed recommendations for better rest.
You can now set alarms directly in the app to wake up at the most optimal time — designed to minimize sleep inertia and support your natural sleep cycles.
You’ll also find a growing library of calming sounds like white noise, brown noise, pink noise, rain, and ocean waves, all crafted to help you relax, focus, or fall asleep faster.

How It Works
Your sleep follows 90-minute cycles through light sleep, deep sleep, and REM. Waking up in the wrong phase leads to sleep inertia — that heavy groggy feeling that can last for hours.
FixSleep calculates the best bedtimes and wake-up times, helping you stay in sync with your circadian rhythm so you rise feeling energized, alert, and ready for the day.
FixSleep is more than a sleep calculator — it’s your guide to healthy sleep, natural wake-ups, and better mornings.
