Some of the best sleep apps play relaxing music or ambient sounds, while others focus on calming breathing techniques and could be considered to be more of a hypnosis app. Here are seven recommended sleep apps to help you unwind and get some shuteye. All you need to do to record your sleep with Sleep Time is place your smart device on your bed’s mattress while you sleep. The app will use your device’s sensors to detect the amount of movement made during your session and collect all of this information in an easy-to-understand chart. This data can be used to compare your sleep quality over weekly, monthly, or even yearly periods. Sleep Time also comes with an alarm clock feature which can use your phone’s vibration, ringtone, or a sound effect from the app to wake you up when you’re in a light sleep cycle. Available on: iOS and Android Sound files range from flowing water and blowing wind to insects and birds; even mechanical devices such as airplanes and air conditioners. Available on: Windows 10 and Android Surprisingly, AutoSleep also provides some functionality for people who don’t like to wear wearables to bed by estimating how long you sleep based on when you took your Apple Watch off and when you put it back on the next morning. This same functionality also works with the iPhone and iPod touch by simply unlocking them when you wake up. Available on: Apple Watch, iPhone, and iPod touch Available on: Android This sleep app also features timer and meditation features, while the iOS version of Relax Melodies can sync Mindful Minutes data to Apple Health. The app provides up to 52 sound files for free and requires a paid monthly subscription of $9.99 for access to additional media. It’s worth noting there’s a $19.99 Lifetime Access one-off payment option for those who don’t like recurring payments. Available on: Android and iOS Interestingly, Pzizz also features a Focus mode, which encourages you to focus on a single task for a set period of time while you’re awake. It’s a strange inclusion, but it works very well. The Pzizz app features an extremely clean design, placing its main features front and center. All of the text in Pzizz is large and easy to read and very little effort is required to navigate from one screen to the next, making it a good app for elderly smartphone or tablet users who often find themselves asking someone for help with their apps. Available on: iOS and Android The colors of the night light are fully customizable, but can even be replaced with a variety of included images. As its name suggests, Night Light And Lullaby also features several music tracks to help kids unwind, too. Available on: Android and iOS
