Look, I've tried enough "privacy" apps to know most are garbage. They either crash when you need them, leave obvious traces, or have interfaces designed by people who've never actually hidden anything.
So I spent two weeks testing the current options. Not just installing them—actually using them for daily tasks, switching accounts, trying to break them. Here's what I found.
What Actually Matters
Before the comparisons, let's talk about what separates useful app hiders from the trash:
Real Stealth
The app shouldn't just hide icons. It should blend in completely. Calculator disguises work because everyone has calculators. Nobody questions them.
Security That Doesn't Suck
Passwords are baseline. Fingerprint support matters. But here's what most people miss: the app needs a panic button. Someone forcing you to open it? Fake crash screen. Plausible deniability.
Multi-Account Handling
If you're hiding apps, you're probably running dual accounts. The good ones handle this without making you log in and out constantly. The bad ones? Data leaks between accounts, notifications show the wrong name, messes everywhere.
The Comparison
| Dimensions | Hide All | Calculator Vault | App Hider Pro |
|---|---|---|---|
| Disguise | Calculator + fake crash | Calculator only | Basic PIN screen |
| Multi-account | Unlimited | Limited | 3 max |
| Fingerprint | Yes | Yes | No |
| Photo vault | Built-in | Separate download | Built-in |
| iOS | Yes | Android only | Yes |
| Price | Free | Freemium | Paid only |
Hide All: The One I Kept
I didn't expect to like Hide All this much. Most "all-in-one" apps do everything poorly. This one doesn't.
The calculator disguise actually works—you can do math in it. I've handed my phone to people who've used the calculator without realizing. The unlock sequence (you set a PIN that ends with =) feels natural. Nobody suspects anything.
Multi-account support is where it shines. I ran three WhatsApp accounts for a week—personal, work, and a test number. No crashes, no notification mixups, no data bleeding between them. That's rare.
The photo vault is fine. Does what it says. I mostly care about the app hiding, and that part is solid.
Who it's for: People who want something that actually works without babysitting it.
Calculator Vault: Fine If You're Android-Only
The original calculator hider. Still works, still simple. If you're on Android and don't need iOS support, it's... fine.
But honestly? The lack of multi-account handling killed it for me. I need more than one instance of apps. If you don't, save money and use this.
Who it's for: Android users with simple needs who don't want to think about it.
App Hider Pro: Skip It
Cheaper, yes. But missing fingerprint support in 2025 is ridiculous. The PIN-only approach feels dated. The interface looks like it was designed in 2018.
It works. That's the best I can say. For basic hiding, sure. But why settle when better options exist?
Who it's for: People on tight budgets who only need the absolute basics.
My Honest Take
I started this test expecting to recommend Calculator Vault for simplicity. I ended up keeping Hide All on my phone.
The difference is reliability. When I hand my phone to someone, I'm not nervous. When I switch accounts, they work. When I need to hide something quickly, it happens without three confirmation screens.
Calculator Vault is fine if you're Android-only and simple. App Hider Pro... exists. But Hide All is what I'll actually use.
