## What is Lock Screen Calculator?

A calculator, right on your Lock Screen.
Make LockCalc your own with custom key layouts and buttons for the calculations you use most.

CALCULATE WITHOUT REOPENING THE APP
Tap “Show on Lock Screen” to start a Live Activity, then use the number and operator buttons directly on your Lock Screen.

BUILD YOUR OWN LAYOUTS
Drag the keypad, operators, and result display into place. Keep the keys you need and save multiple layouts for different tasks.

TURN A FORMULA INTO ONE BUTTON
Combine numbers and operators to create custom calculations, such as adding tax and rounding down. Test your formula before saving it.

CORE FEATURES ARE FREE
Use the calculator, manually show it on the Lock Screen, edit layouts, and create custom operators for free.

BRING IT BACK AUTOMATICALLY
iOS ends a Live Activity after up to 8 hours. The optional Automatic Redisplay In-App Purchase brings your calculator back without reopening the app.
Try it free for 7 days. Automatic redisplay stops when the trial ends; continuing requires a one-time purchase. There are no automatic charges or subscriptions.
