I would like to have a simple app that would let me define a time, a beep sound and a pattern. So I could have a one beep timer [1] and an interval timer [2]. I use those for exercise, but I'm not entirely satisfied. Bonus points if the beep sound could be configurable to notification sounds, sfxr UI [3] (maybe it could be be another simple application) and speech synthesizer.
