ExpTimer

ExpTimer is developed as an easy-to-use timer to facilitate complex, multi-step experimental protocols.
The advantages of ExpTimer are that it takes away the fiddling around with typical lab timers, which have to be reset after each action, and at the same time it shows you what to do next. You just enter your own protocol, press “start” and you do not have to worry about timers anymore, especially when you already have your hands full with your protocol. If something goes wrong during your experimental procedure, just press “pause” (to pause the timer) or “reset” (to start all over again).
Of course, the program has a much broader area of application than experiments only.
