Ever thought about what goes on while you’re sleeping and you don’t even realize it? With BetterSleep’s new Sleep Recorder, you can understand your sleep habits in ways you never thought possible. Released earlier this month, the BetterSleep app (available for download on both the App Store and Google Play) now gives users a whole new insight into what happens after they’ve hit the hay.

Here’s what else you should know about this exciting new feature, and how it can change the way you think about your sleep.

How Do You Set It Up?

When you open the BetterSleep app, you’ll be prompted to enable the microphone on your mobile device. This is important, as you can’t record what happens while you’re sleeping if you leave your mic turned off! Once you tap “Enable Microphone”, you’ll be able to record your sleep until you turn it off upon waking up. When prompted, hit the “Sleep” tab to begin recording.

The sounds you make whilst asleep will be picked up, tracked, and analyzed in the app, with a sleep report being generated afterward to give you detailed statistics on your sleep habits during the night. Remember to leave the tracking and recording on for as long as possible, as a report won’t be processed if you don’t have it activated long enough. Tap the “Journal” tab to see the results, including recordings of sounds you’ve made, how much “sleep debt” you need to make up, and what your ideal bedtime should be based on your data.

What Does the Sleep Recorder Actually Record?

Once you turn on the sleep recorder, the app will analyze how many times you make certain sounds in your sleep—talking, snoring, gasping, even farting! The more you go to sleep with the recorder on, the more data you’ll have to analyze your sleep patterns. If you start making changes to your lifestyle, you can use those analytics to see if they’ve led to any variations in sleep habits. This feature can also point out causes of sleep disruption possibly indicating certain disorders, such as narcolepsy (if you find yourself waking up often) or sleep apnea (if you tend to snore and/or gasp loudly).

After you wake up, you can listen back to parts of your recordings, where you may just notice things you never even thought you did in your sleep. Using both the recordings and the data produced, you can better understand how you behave while asleep, and make the lifestyle changes necessary to make your sleep quality better than ever!
