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.

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

Too many pop ups, too expensive, no auto save. I haven't paid for the app, and it's just under $60/year for a subscription, not a one off (which would be too expensive anyway), which is ridiculous. Instead of loading straight up to the home screen, it pops up prompts to "encourage" you to pay, every time time you open the app. The X to close is almost completely transparent which is incredibly dodgy. The sleep reports don't auto save so if the app crashes you lose all the data from the night.

Best app I've tried so far. I mainly download it to catch my sleep talking as I have a sleep disorder and often talk a lot and keep my partner up. It can sometimes pick up recordings when there is no sound, and sometimes can miss some sleep talking or mislabeled the recordings, but it doesn't affect the app use too much and I still think it's the best app I've tried yet.

I've used the app for two nights so far and I'm pretty pleased with the unpaid version. I'm trying to keep better track of night terrors to see if I can find a pattern of what brings them on if anything. The app records sleep talking and snoring into small clips so you can easily and quickly listen through. It also has a really cool feature which lets you make a bedtime routine. I would recommend this if your wanting to track disrupted sleep and find out more about what's going on.
