I have g-alarm on my TP and love it! I'm also very happy with the 2.1 alarm BUT you only have 3 alarms. I had about 6 set up on the TP. Soooo, I still use my TP for my wake up and "get your a$$ to work" alarms at home and use my Evo for other things.
I only wish I had more than 3 alarms to use. I may try out Alarms and see if I like it.
