A3Calc vs Bluetooth Radar Finder

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?

Bluetooth Radar Finder helps you detect and locate nearby Bluetooth devices in real time. Use the live radar scanner to view nearby devices, check signal strength, and track whether you are getting closer or farther away. The app shows nearby Bluetooth devices on an animated radar screen with distance-based positioning and signal color indicators. Tap any device to open a detailed view with signal strength, RSSI, estimated distance, and live movement trends. When you enter Find mode, the app uses sounds and haptic feedback to help guide you toward the device. You can save important devices for quick access and receive alerts when they go out of Bluetooth range. Bluetooth Radar Finder also records the last known location where a saved device was detected and displays it on a map. Detection history is stored with timestamps, signal data, and GPS coordinates, and can be exported as CSV when needed. To improve stability, the app smooths signal readings and uses calibrated distance estimation when device broadcast data is available. It also supports accessibility features such as VoiceOver and includes full English and Spanish localization.
