Wow! Just perfect. I entered 11 complicated timing sequences easy peasy this morning, and in operation the timer integrates beautifully with music, can vibrate, has an easy to read collie coded display, etc. -- it even lets you export your timer setup data (and import backups), and even record your own sound if you like.
Heck, you can share, download, or both timers from the community.
I LOVE this app (however, if you want, check out their "UltraTrainer" app which does everything this does, plus give you the option of some randomized inputs as well: Simply astonishingly well-thought out software!
