Many of us have difficulty falling asleep. Whether it’s every night, a couple of times a week or randomly throughout the month or year. Falling asleep and remaining asleep can be challenging, draining and frustrating to say the least.

However, whatever troubles you have when it comes to sleeping may be solved by the power of sleep app technology. With so many sleep apps on the market nowadays for both iOS and Android devices, we’ve taken the liberty (and hopefully saved some of your time) of selecting the very best apps to help you sleep, night after night.

So sit back, relax and head to your App Store or Play store.

Do sleep apps really work?

  • 89% improve their sleep quality.
  • 84% have less disturbed sleep.

Science-backed apps like Pzizz, which are backed by the NHS, use the latest clinical research on sound for sleep. Other apps like Calm, MyKokoon and Headspace use well-known calming and sleep-inducing methods such as meditation and hypnosis.

Which sleep app should you choose?

Ask the following questions:

1. Is the app specifically designed for sleep?

Make sure the app has been developed with sleep in mind. If the app has techniques for relaxation and winding down, then these apps should help you to sleep. Avoid apps which don’t mention sleep or relaxation, as they’re probably not what you’re looking for. Start with our best apps’ list and go from there.

2. Has the app got accredited reviews?

Ensure the app is trusted and well-known by other users. Reading reviews can help you to decide whether the app is for you. Many quality start-up apps are new so don’t have many reviews, so therefore you may have to investigate these more thoroughly and do your own review/research.

3. Do you want a free app or are you willing to pay for access?

You might not want to fork out any money for an app, so if that’s the case you’ll need to find an app that’s free and worth the time you’ll be investing into it. Bear in mind that a free app doesn’t mean the app won’t be good, it can just mean that you’ll receive limited access or if it’s a start-up, your free access may suddenly stop once the business develops or changes tack.

What is the best free sleep app?

MyKokoon’s audio varies from meditations and storyscapes to coloured noise and hypnosis. At the moment access is free and you can tune into all of the sleep audio on offer, whether you own a pair of Kokoon headphones or not. So grab the chance while you can!

What is the best app to help you fall asleep?

MyKokoon’s selection of sleep audio will help to nudge you into the land of nod. A 10-minute relieving tension audio or an 18-minute Mindful Moments audio is often all it takes to help you fall asleep.

The only way you can truly find out which app works best for you when it comes to helping you sleep, is to try them out. It’s worth trialling your chosen apps for at least a week (unless you really aren’t getting on well with it). This will allow you to get used to how it works, which features suit you and what audio helps you to switch off and nod off.

Why not start with MyKokoon this week? And begin your journey to a better night’s sleep.
