A3 Small Format Interchangeable Core Calculator (sister app of A2Calc and A4Calc) ---Programmed by a Locksmith, for Locksmiths--- Automatically calculates the pinning chart for A3 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. Found a bug? Something not working? Have a suggestion?

Verdict
The clearest difference is price: REALLY at Free against A3Calc's $1.99. REALLY also leads on update cadence (every 2 weeks vs every 18 months). A3Calc's advantage is iOS requirement (12.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
