Calculator photo vault apps

An app that looks like a calculator hides the fact that a vault exists. The disguise says nothing about encryption, so check that separately.

The concept is simple. You download an app with a calculator icon. It adds and subtracts like a real one, and when you type a chosen number, it reveals a stash of photos. This page covers the category in general and makes no claims about specific apps.

Strengths of the disguise

A calculator icon draws no attention on a Home Screen. A kid or a nosy friend scrolling through apps will likely pass over it, and someone who opens it may just find a calculator. Many of these apps also use a separate code, which adds something that the Hidden album lacks.

Gaps in the disguise

Encryption is a separate question. A convincing front door tells you nothing about what is behind it. The photos could be fully encrypted or merely tucked into the app’s folder. Check, using the questions in our app checklist.

The name still appears. iOS lists apps in several places. App Library shows the real name, and Apple says hidden apps can still appear in Screen Time, Battery settings and your App Store purchase history. The app’s store listing often says what it does. A person who looks up the name will learn what it is.

A second calculator looks odd. Apple’s Calculator comes installed. A person who knows phones may wonder why there are two, particularly if one is tucked away.

Popular apps become known. Searches for ways to detect calculator vaults are common. Once people know the trick, an icon offers less cover.

Combine a disguise with iPhone’s own tools

If you downloaded the app, you can lock it or hide it:

1. Touch and hold the icon.
2. Tap Require Face ID.
3. Tap Hide and Require Face ID, authenticate and tap Hide App.

Now it opens from the Hidden folder in App Library. The tradeoff is that a Hidden folder also tells a careful person that you hid something. See hiding and locking apps for the other limits.

Plan for the things that go wrong

A forgotten code. With a disguised app, you may not have a visible hint or reset button. Find out how recovery works before you add your photos.

A deleted app. A family member tidying the phone may remove a spare calculator. Apple says deleting an app removes its data from the iPhone. Keep a backup or export of anything irreplaceable.

Ads. Consider how an app that holds private photos makes its money, and whether ads are a good fit for that.

Situations where hiding an app can backfire

A secret app can protect you in many relationships. If someone already controls or monitors your phone, finding a disguised app could make things more dangerous, since it looks like deliberate concealment. In that situation, please talk to an advocate before you install anything. Our page on monitoring lists free, confidential hotlines.
