Fence! (Pro) is a more advanced version of Fence! Fence! (Pro) has been designed from the ground up for fencing referees. The app features easy to user timers, large button targets, and an uncluttered display. Optical scanning of standard FencingTime pool sheets lets you track fencers names, numbers, and results in your phone, saving you precious seconds at the end of every bout. Fence! (Pro) understands every aspect of a fencing match, from standard pools to DE bouts to team events. At every step, Fence! (Pro) knows what should happen next and makes it easy for you to move to the next step. (Time expired in the first period? The app immediately asks to start the rest break timer. Passivity time reached? Time for p-cards!) Fence! (Pro) incorporates the new USFA passivity rules and keeps a separate passivity timer, letting you keep your focus on the action. You can still use Fence! (Pro) in "practice" mode for simple bout situations.

Blackboard-Stopwatch This app is a simple stopwatch with very large numbers. The app has only one button with 4 functions: start, stop, pause and reset. In conjunction with my Bluetooth device and a photocell it can be a good display panel for any type of race. In this way, the use has practically no limits. Advertising can be deactivated via the "In-app purchases" option. For the start/stop can be used an external Bluetooth-button.
