Absolutely recommended

This is the best birthday/event App I have found for the iPhone. iDay joines best functions found in other Apps into one App and adds other features on top.
If you want to manage birthdays, events or holidays all in one App then buy this. The best for me is the creating of birthday mails with all the sophisticated information of a special day. You canot be dissapointed.

@yo_2phone: are you sure you have used the same App? I use iDay for weeks and I have got no crashes and no problems.
iDay rocks really! :-)
