Features
Understand the app, one feature at a time.
The everyday calculator, exact-equation entry, separate collections and device-only storage. Explore how each part fits into your photo routine.
Your equation opens your vault
Enter the exact equation associated with a vault, then press equals twice. Remember the expression itself, not merely the number it produces.
Give each collection its own vault
Separate vaults let you give different photo collections clear boundaries. Start with a few meaningful purposes and a repeatable import routine.
Photo vaults that stay on your device
CalcLock uses device-only photo vaults and does not require an app account. That keeps the workflow local while making device planning important.
A real calculator, with a deliberate vault entrance
CalcLock is a functioning calculator. A matching exact equation followed by equals twice provides a deliberate route into a photo collection.
