Apart from creating your own ringtones, the app can record other audio as a notification alert for email or SMS. It's free for Android phones and $1 for Apple products.
It can also be used to create a custom sound to identify an app on your phone, like a weather app or a sports app. To set up custom sound for an app, open that app's settings, then tap sounds.
If your iPhone has a lot of contacts, you might want to set a different ringtone or text tone for each of them. On an iPhone or iPad, it's a fairly simple process. On an Android phone, it's a bit more involved.
First, open the contact you want to set a ringtone for. You can access a contact's profile in the Contacts app or access it by tapping your phone app icon and contacts in the lower right corner of the screen.
