CalcLockAt a glance: CalcLock keeps the first equals press ordinary: it displays the answer. Only a second consecutive press opens the vault for that exact equation.
A real calculation before the reveal
Enter your exact equation and press equals. The calculator shows the normal answer. Press equals again to open the matching vault, without a visible vault directory on the calculator screen. That extra step keeps ordinary calculation separate from entering a collection.
123+123 and 200+46 both produce 246, but they produce different keys and open different vaults. Knowing the answer is not the same as knowing the equation.
How that differs from PIN-and-equals entry
CalcLock by Cloud Strategy documents entering a numeric PIN and pressing equals to unlock. Its support page also describes an optional Face ID or Touch ID icon on the calculator screen. Calculator Lock – Secure Vault describes entering a password and pressing equals in its App Store listing.
CalcLock’s distinction is the ordinary answer before the reveal, followed by a second equals press. It is a more subtle transition than going directly from a PIN to a gallery. These are documented entry-flow differences, not an independent security ranking.
A calculator icon is not the whole experience
Vaultaire offers a calculator-style app icon, but its icon documentation says the app opens to its pattern screen. CalcLock instead opens as a functioning calculator and uses an exact equation to enter a collection.
Discretion and encryption do different jobs
CalcLock encrypts its files and their names using keys derived from your exact equation and a device-bound secret. A simple equation remains easier to guess, and the design has not had an independent security audit.
The interface is designed to be discreet, not undiscoverable. There is no recovery or portable backup if you forget the equation or lose the device.
