I migrated from a Compaq iPAQ 2200 series to an iPOD Touch as a PDA and handheld computer. The calendar and a PPC program called Calendar + allowed me to do complex repeats (e.g. 3rd Thursday of each month). When I got to the iPOD's calendar and found that I couldn't do that I was really disappointed. Enter Calendar Tools. It does everything I could do on the iPAQ. The author(s) say that this is an add-on to the native calendar app. I'm glad of this; I find the views in the native app better than the views in Calendar Tools. Just my taste there. I also like that I can switch back and forth between them for certain kinds of tasks and know that my data will be accessable in both.Beyond the possibility of complex recurrences, there is another function that I love in Calendar Tools: I can look up appointments alphabetically. If I know that I shceduled a meeting with John Smith but can't remember the date, I can look up "John Smith meeting." That was something I couldn't do before.The most confusing thing I found was in setting up a complex recurrence: when the event is initially set, you are given the choice of somekind of simple recurrence or no recurrence. You need to choose somekind of simple recurrence, finish the event and then choose that event, tap on the box on the upper right of the main screen screen and edit the recurrence to a custom recurrence. It took me about 15 minutes to figure that one out.That being said, the learning curve isn't that steep and the functionality is worth it. I heartily reccomend this app.

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.

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.

From what I can tell, the app takes over the "repeat" function from iCal. If you attempt to set up a customized repeat in Calendar Tools, then the repeat function is no longer visible from i Cal.The home screen on Calendar Tools lists "events" by date that are taken from iCal. You can filter them according to date or event. You can see either see appointments according to days between two dates you specify, or you can see them according to the type ("x meeting").From the home screen, you can click on an event ("x" meeting) and then add a "custom recurrence". You can specify 3rd Tuesday of the month; 2nd Friday of the month on a repeat daily/weekly/monthly basis. However, when you click "Done" nothing happens, so you cannot save the custom repeat. In effect, the very feature for which you buy this app does not function.Also, the app states in the FAQ that you can either add an event in iCal or in Calendar Tools with custom repeats. This is inaccurate on both accounts. If you open up iCal, you get the standard repeat options that comes with it (none, daily, weekly, 2 weeks, monthly, or yearly). If you open up Calendar Tools to add an event, you get the exact same options - no customizable repeats as advertised.In short, this app is a waste of money - it does not do what it is advertised to do. Don't buy it.I put in a request to Appiplayer to refund my money. If they are at all reputable and refund my money, or make the fixes to make this app functional the way it is advertised, I will add their response to my review and report the outcome. It's such a crazy thing that getting customized repeats is such an elusive function when it is available so readily on other platforms. Frustrated.
