We make Noxium, one of the apps in this comparison, so weigh our picks with that in mind. Every other app's row comes from its own App Store page, linked in the table. We did not install, test or audit other apps.
What matters in a photo vault
A photo vault is only as good as three things: how it encrypts your files, whether your photos survive a lost or new phone, and what happens if you forget your code or stop paying. Most low ratings for vault apps are about those three things, not about missing features.
- Real encryption, on your device. A PIN screen in front of normal files is a lock on the front door with the back door open. Look for a named cipher such as AES-256, and for encryption that happens on the iPhone before anything is uploaded.
- A backup that restores. Ask where the backup lives (your iCloud or the developer's servers), who holds the keys, and how you restore on a new iPhone. Backup and new-phone failures are among the most common complaints in vault app reviews.
- A way back in. If nobody can reset your code, you need a recovery phrase or key you keep yourself. If the developer can reset it by email, they can also, in principle, get in.
- Getting photos out. Check that export keeps full quality and original dates, and that it isn't behind a paywall.
- Honest pricing and privacy. Check whether ads or a lapsed subscription can lock your photos, and read the App Store privacy label.
