Do you have a hard time waking up? Do you wake up groggy?

Start your day right and wake up feeling refreshed. Studies have shown that interrupted sleep may be as harmful as no sleep at all.


There are a number of sleep stages your body goes through when you are sleeping at night. It’s far more difficult to wake up during deep sleep because the rest of your body is still sleeping. Waking up during light sleep is the most optimal way to wake up feeling energized and refreshed.


Set your alarm and place your phone next to you before you sleep. Zen Sleep Cycle Alarm Clock analyzes your sleep cycles and wakes you up at your lightest stage of sleep within a 30 minute window of your alarm. You’ll wake up naturally feeling refreshed and energized.


The app has many features to actually help you get better at sleeping. It measures your sleep efficiency every night and shows each stage of sleep. Track and analyze your sleep patterns and log events that affect your sleep efficiency. Start keeping a record of your dream logs! You’ll discover new and interesting things that can help you along your journey. Eating late might cause vivid dreams. Maybe using electronics before bed causes you to take longer to enter the deep stages of sleep. Use these tools to improve your sleep efficiency and improve your health.

Waking refreshed

I don’t know how the app does it, but it has waken me during my lightest sleep two days in a row and I feel refreshed. I might have to upgrade, because the free app doesn’t have all the features and there are some annoying ad pop-ups. Otherwise, I am satisfied after two nights.

This is crap

Turned this stupid alarm OFF, it turns itself back on. The only way to stop this piece of crap from going off when you're trying to sleep is to change the alarm time to something ridiculous like 11pm. It will not turn off no matter how many times you turn it off, it turns itself back on once you leave the alarm seeing screen. This app is gone so I don't ever use it again by accident and rub another night's sleep. Much better out there - that STAY OFF when I turn them off. All I wanted was the sleep tracking. I could've just stayed awake and may as well have because after less thantwo hours of sleep this piece of crap woke me up so I get NO MORE SLEEP and I have stuff I have to do today, would've loved to get more than an hour's sleep and I won't give this piece of crap the opportunity to ruin my night ever again.

Well done with excellent Features from the rest

I’ve been looking for a less “alarming” alarm clock. I like the features that allow for more natural waking through you sleep patterns. The sounds are pleasing and even can track dreams and factors that can affect sleep. Ironically I’m writing this at almost 1am on a weekday, hoping I can sleep. Creators well done!! Thank you!!❤️👏
