HideX has over 100 million downloads. Calculator Hide App has become the go-to choice for users who prioritize real encryption over feature bloat. Both disguise themselves as calculators. Both promise privacy. But they work very differently under the hood.
This comparison covers the things that actually matter: how they handle your files, which features hold up in real use, and where each app falls short.
Quick Verdict
Calculator Hide App is the better choice if your priority is genuine file security and AES-256 encryption. HideX is better if you want a wider feature set — multiple vaults, VPN, app cloning — and are comfortable accepting that some of those features are restricted behind a paywall.
Encryption and File Security
Calculator Hide App
Calculator Hide App protects your files with AES-256 encryption — the same standard used by banks and governments. When you import a photo or video, the file is encrypted immediately before being stored. The original file can be deleted from your gallery, leaving no accessible copy outside the vault.
HideX
HideX advertises encryption but independent reviews have found that in some versions, files are stored in a hidden folder rather than being genuinely encrypted. One widely-cited Play Store review notes that files found in HideX’s storage directory were unencrypted and directly viewable. This is a meaningful distinction — hidden is not the same as encrypted.
Disguise Quality
Calculator Hide App
The calculator disguise is fully functional. Every button works. You can do real arithmetic with it. The PIN entry is seamless — you type your code and press ”=” to open the vault, exactly as if completing a calculation. There is no visual indicator that a vault exists.
HideX
HideX also uses a working calculator disguise and adds the ability to change the app icon to something other than a calculator — a clock, browser, or other utility. This icon-switching feature is an additional layer of disguise that Calculator Hide App does not currently offer. If changing your app icon to disguise a vault app is a priority, see our guide on how to change app icons for disguise purposes.
Intruder Detection
Calculator Hide App
The intruder selfie feature is on by default. Every wrong PIN attempt triggers the front camera to silently capture a photo of whoever is trying to get in, timestamped and saved inside the vault where only you can see it.
HideX
HideX calls this “Break-in Alert” and it works the same way — a photo is taken after failed PIN attempts. The feature is present in the free version.
App Hiding (Android Only)
Calculator Hide App
You can hide installed apps inside the vault on Android. This removes them from your home screen and app drawer — they are only accessible from inside the vault.
HideX
HideX also offers app hiding and goes further with app cloning — you can run two accounts of the same app simultaneously (for example, two WhatsApp accounts). This is a genuine differentiator for users who need dual-account functionality.
Private Browser
Calculator Hide App
The built-in private browser leaves no history on your device. Downloads go directly into the encrypted vault. It is designed specifically so that browsing activity cannot be seen in your phone’s regular browser history.
HideX
HideX includes a private browser plus a VPN service. The VPN masks your IP address in addition to clearing browsing history. This is a more comprehensive privacy tool — though VPN reliability varies and some user reviews report connection instability.
Cloud Backup
Calculator Hide App
Cloud backup is available and stores an encrypted copy of your vault. If you lose your device or uninstall the app, your files are recoverable by signing in and restoring.
HideX
HideX offers cloud storage and promotes automatic syncing. However, several user reviews report that cloud files are not encrypted in the cloud — they are managed by Google Drive in an open folder. If accurate, this means your “private” files would be visible to anyone with access to that Google Drive account.
Ads and Free vs Paid
Calculator Hide App
The app is free to use. Ads are present but not invasive. Core privacy features including encryption, intruder selfie, and cloud backup are available without payment.
HideX
HideX is free but ad-supported with a notable catch: some core features are paywalled. The VPN, unlimited cloud storage, and some disguise options require a subscription. User reviews consistently mention that ads are frequent and sometimes intrusive.

Choose HideX if you want extras like app cloning, icon switching, and a VPN, and you’re willing to pay for a subscription to unlock the full feature set. Just be aware of the unresolved questions around cloud encryption.
Frequently Asked Questions
Is HideX actually safe?
HideX is safe as a basic vault app. The concerns are specific: some file versions may not apply true encryption, and cloud files may not be end-to-end encrypted. For locally stored media accessed only on your device, HideX functions reliably.
Can Calculator Hide App hide apps like HideX?
Yes — on Android, Calculator Hide App can hide installed apps from your home screen and app drawer. The difference is that HideX also offers app cloning (dual accounts), which Calculator Hide App does not.
Which is better for iPhone users?
On iPhone, both apps focus primarily on photo and video privacy since iOS prevents third-party apps from hiding other apps. The encryption advantage of Calculator Hide App is more relevant on iOS.
