Good App


But it is missing 2 features that I should think are rather obvious.
1) Custom recurrences cannot recur annually. So you can't set up an event like a holiday that happens on the same day of the week every year, like say, Easter or President's Day. Luckily the app "US Holidays - Add them all to your Calendar" will do just that for you automatically, as well as having options for religious holidays too.
2) You can delete individual occurrences of events, but you cannot delete an event and just tell it to delete all future occurrences as well. Luckily Week View Express can do that, and it's free.
The above functions were really te reasons I bought this app. It seemed certain that it would do both of those things, but it does not. It's great I suppose if you have a problem with duplicate events or you need to set up weird recurrences that are weekly or monthly. But I don't, so those other 2 apps I mentioned worked far better for me at a fraction of the cost.

Thank You!


I really like this app. It does just what I need. I can now easily set up birthday or anniversary alerts on the iPhone. Choose an anniversary from address book and create two alerts. The first is one week before. It is time for me to prepare gifts. The second is on the date of this anniversary. I will never miss a birthday or anniversary again.

Had a bit of trouble at first but support was very helpful. They got me going with clear instructions which included screenshots after 3 email exchanges. They appreciated my suggestions on how to make instructions clear and said they are working on it. After learning to navigate the app it is really helpful and is all it says it is. With clearer instructions I would give it 5 stars.
