A3Calc vs Alt Time

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?

Alt Time puts the times you actually need on your lock screen and home screen. See the opposite of your iPhone's clock format at a glance. If your phone shows 12-hour, the widget shows 24-hour — and the other way round. It follows your system setting automatically, so there is nothing to keep in sync. WHAT YOU GET Dial — a home screen clock face with two rings of numbers: 1–12 outside, 13–24 inside. The hour hand points at both at once, and the centre shows the time both ways, like 5:57 PM and 17:57. Small, medium or large, in ten finishes including parchment and black enamel. Show your own time or any city from your world clock. World clock — a home screen widget in small, medium or large, showing as many cities as you like in eight color finishes, with a sun and moon day-night glance. Looks right in StandBy. Alternate 12h/24h time — always the opposite of your system setting, updated automatically. Second time zone — search about 69,000 cities, not just capitals, and see that city's time labeled with its name. UTC / military time — 24-hour Zulu time for pilots, sailors, and anyone working across zones. Dual-time widget — two times side by side in a single lock screen slot, sized to match. Lock screen and home screen widgets, in circular and rectangular slots, tinted or clean. COMPLETELY OFFLINE The city database is built into the app. Searching it needs no network, so Alt Time works in Airplane Mode, on a plane, or with no signal at all. Nothing is uploaded, because there is nowhere for it to go. NO SUBSCRIPTION One purchase. No subscription, no ads, no account, and no data collected, stored or transmitted — ever. Requires iOS 17 or later.
