About this app

How did you sleep last night? 🌛

Sleep Monitor helps you track and record sleep cycle details. Sleep Monitor also has a smart alarm clock to remind you to sleep early at night and wake you up gently in the morning. In addition, Sleep Monitor provides relaxing sleep music to help you sleep better.

Key Features:
📊- New Feature: Sleep Trends
Improve sleep quality and develop better sleep habits with weekly and monthly data statistics.

🎙- Record Snoring or Dream Talking
Sleep Monitor will record snoring and grinding sounds made during your sleep, listen to them, and find more about your sleep the next morning! For fun!

💤- Mark Your Sleep Habits
If you drink, eat, exercise, have any pathological condition or depressed emotions before sleep, see how these slumber habits can impact your sleep.

📲- Track Your Sleep Phases
Sleepers will have 4 or 5 sleep cycles during the night. Usually, sleepers will pass four sleep stages in one sleep cycle: Non-REM 1(between waking and sleep), Non-REM 2(light sleep), Non-REM 3(deep sleep), and REM (Rapid Eye Movement, when most dreaming happens) sleep. These stages progress cyclically from 1 through REM then begin again with stage 1. A complete sleep cycle takes an average of 90 to 110 minutes, with each stage lasting between 5 to 25 minutes.

Sleep Monitor uses both microphone and accelerator sensors to measure body movements and environmental noise changes and then recognize your sleep stages.

📈- Get Your Sleep Score
Sleep Monitor will generate useful information for you after tracking, like sleep score, sleep cycle graphic, sleep statistics, sleep noise audios. Get your daily, weekly, or monthly sleep insights and use those data to help you sleep better. Sleep Monitor is especially helpful for those who want a way to check how their sleep is, and do not want to invest in an accessory like a smart band or smartwatch.

⏰ - Set Smart Alarm Clock
Set an alarm for your morning wake-up or nap or set a reminder for bedtime.

🎵- Listen to Soothing Lullabies
Suffering from insomnia? Listen to high-quality relaxing music to calm a racing mind before sleep. Fall asleep quickly with different kinds of sleep sounds.

✍ - Write Sleep Notes
Take brief notes for your sleep. Write down anything you want so you will never forget about them.

BEWARE: I bought this app based on an advertised trial period that I could cancel. Even though I cancelled within a few hours, I was still charged for the entire month. Google Play refused to address it because it is apparently their policy that all sales were final and I was told to contact the company- who was foreign and, of course, did not assist. Bottom line: don't fall for the free trial language. The app isn't that great anyway.

Works fine until you're ready to cancel your subscription. Here's my experience... I clicked on cancel subscription. They sent me to Google Play, where, NORMALLY, you SHOULD be able to cancel through. Except, the application is not listed within the list of subscriptions. Being that everything else works through this app, I have to assume that this is done intentionally. So I will give a 1 star being that this is shady as heck. Still unable to cancel my subscription. Do better.

i opened the app, and IMMEDIATELY got bombarded with temu-style scams. "You won a free trial from this spin wheel!!" shut up. The app is constantly trying to push you to buy something from the MOMENT you open it. It uses tactics that those ai weight loss apps use, too, when you first download it. it's probably completely just a data selling scam.

Sorry for the poor first impression. 😔 Our app is not a scam, and we never sell user data. Some pop-ups show premium offers, but they can be skipped. Thanks for your feedback — we’ll keep improving the experience.
