Photo Vault

If you only want to save or hide your pictures and videos, Photo Vault it’s a great option for you. Photo Vault lets you save and manage the pictures and other types of media on your iPhone or iPad. You can save your pictures, download images right to the app, and even edit them from the app. Also, you can send your pictures or video via email or messages.
It also has a decoy password, which you can set up to cover your real pictures. If anyone enters the decoy password, the app will show them other pictures and hide the real ones, which is pretty neat if you need to share your iPhone with someone else.
You can lock the app with an alphanumeric lock, PIN lock, or Face ID. Plus, if you’re a forgetful person, Photo Vault lets you recover your password by using a security question. Not many secure folder apps offer this option, so you might need to consider this app if you want to have the chance to recover your password.
