At first glance, Timekeeper is exactly what you’d expect. Start the timer, stop it and check the time. Nothing unusual to see. But for the magician, Timekeeper can be used to secretly calculate and reveal information, opening up possibilities for card magic, memorised deck work, spelling effects and routines where you need to quickly determine a position or piece of information without any obvious calculations. The idea is simple: the method stays hidden inside something completely ordinary. Rather than reaching for a specialist magic app or obviously performing calculations on your phone, Timekeeper disguises everything within an innocent-looking stopwatch interface. Built for Magicians Timekeeper is particularly useful for memorised deck and card spelling effects, giving you a quick and discreet way to access the information you need during a performance. It’s designed to be a utility rather than a single trick, meaning you can experiment with it and find ways to incorporate it into your own routines and existing magic. No App Store Required Timekeeper is a web app, so there’s nothing to download from the App Store or Google Play. Simply open it in your phone’s browser and add it to your Home Screen. Once installed this way, it opens and behaves much more like a normal standalone app. It works on both iPhone and Android, although the current design has been developed primarily with iPhone in mind. Completely FREE No purchase. No subscription. Just another useful tool we’ve created for magicians and made available to our community.
