This app works so good! I use it for my business to remember anniversary dates of contracts (annuities, etc.) and also dates when spouses die so I can send a card in the future. There are so many uses and it does work flawless! This app brings Address Book to a truly useful and professional level. I recently upgraded to Lion and also iCloud, and when I had an issue, I was emailed the solution within 5 minutes and it was right back to normal. This program is worth it's weigh in GOLD. It is sincerely one of the best apps I have ever downloaded. Don't hesitate to purchase!!! 10 out of 10!!!!I It also works on putting the dates on my macbook air, and 2nd iMac and also iPhone.
