About A4Calc
A4 Small Format Interchangeable Core Calculator
(sister app of A2Calc and A3Calc)
---Programmed by a Locksmith, for Locksmiths---
Automatically calculates the pinning chart for A4 SFIC. Built for 6 or 7 pin systems, however, less can be achieved by using a decimal to erase a chamber.
Minimum of a control and master key are required to make a chart. Additional change key available for all devices; 2 change keys available for 16:9 screen devices.
Randomize function will generate completely random charts each time it is triggered.
"Lock/Unlock" toggle disables/enables all inputs and functions to prevent unwanted/lost changes.
Control Finder is an added bonus by reverse engineering a core to determine the control key's bitting. This is perfect when needing to remove multiple cores in a building when the control key has been lost. There are two methods for achieving the control key: 1. using the master, control, and bottom pins, or 2. using only the top/driver pins.
Up to 16 different projects can be saved at any one given time.
All projects are encrypted and protected with a passcode when stored on your device.
All projects can be exported via AirPrint and Email.
Compatibility: iPhone / iPod touch on iOS 8.0 or later and iPad on iOS 12.0 or later.
