5 Best Ways to Lock Apps on iPhone

Apple prides itself on offering iPhones with the best security features. From passcode to Touch ID to Face ID, Apple has tried to improve the security of user data on its devices. However, you would still want to add another layer of protection to apps installed on your iPhone.
