[Hide photos no one should see — inside this calculator.]

Calc+ looks and works like an ordinary calculator. But enter your secret 4-digit passcode, and a hidden photo album appears.

Hand your phone to a friend. Let your partner browse your home screen. No one will ever suspect this app is anything but a calculator.

■ Perfect camouflage

The icon, the interface, the functionality — it's a real calculator. Portrait mode for basic math, landscape for a full scientific calculator. Use it every day without raising suspicion.

■ 'Show me' — no problem.

Calc+'s killer feature: the Decoy Password. If someone asks you to open the app, just enter your decoy code. An empty fake album opens — with no settings button visible. Your real secrets remain completely hidden.

■ No biometrics — by design.

Face ID and Touch ID are convenient, but they can be forced — while you're asleep, or simply by pointing your phone at your face. Calc+ relies only on a 4-digit passcode that exists nowhere but in your mind. No one can force what they can't see.

■ Photos and videos, safely stored

Save photos and videos inside the app. Smooth playback, folder organization, pinch-to-zoom grid — it feels just like your regular album.

■ Premium Plan (one-time purchase)

Pay once, unlock everything forever. No monthly fees. No recurring charges on your credit card statement.

· Unlimited photo & video storage · Decoy password feature

Protect your secrets with Calc+ — starting today.
