If you’re new to white noise apps and want to go for one with a large user base, Calm may be a good option. It has an “Editor’s Badge,” with over 50 million downloads on Google Play and a high rating of 4.5 out of 5 stars. It’s also one of the top-grossing apps in the health and fitness category.

When you open the Calm app, it will ask you about your goals, such as reducing stress or anxiety, improving performance, or getting better sleep. You can create an account using your email address, Facebook, or Google account. There will be prompts to upgrade to the premium version, but you can close them if you’re not interested.

While Calm is primarily a meditation app, it also offers various sounds that you can play as white noise for better sleep or focus. Simply tap the search bar in the Discover tab, choose Soundscapes from the Category dropdown, and browse through the available tracks. You can also try the Sleep Stories category for an alternative to white noise. Free content will have a play button, while locked content can be accessed with a paid subscription. Calm Premium costs $4.99 per month and comes with a 7-day free trial.
