Great cal app! ,

Meets my needs!

This was the best free complex calendar that I could find. I needed a calendar that could do repeat events such as the 3rd Thursday of the month or an annual event on the 2nd Sunday in March. With this calendar, not only can you set up these type of repeat events, you can add multiple alarms (more than 2) and add notes/comments! Also, it synchs to ICal which allows multiple calendar views. I love this app!

It was free and not worth rhat

Ugh! I got it for free and it is awful. I cant read it print is small cant make it bigger that i can tell. Every time i open it it wants access to my contacts. There us no reason to need access my contacts other than data collection. No redeeming qualities in this app

App Malfunctions But No Tech Support

Although I like this app, for the past 3 days or so, the sync function (via Dropbox) which was recently fixed, has begun to malfunction in the same way it was before.

Upon syncing my iPhone or iPod Touch using the "Restore" function, the system always indicates that the operation was successful, but looking at the calendar afterwards, none of the new engagements appear. At first they were appearing little by little after a significant lag. However, that stopped working and then I had to sync/restore a bunch of times, close the app, then reopen it and then new engagements would appear - usually. When that stopped working I had to sync/restore a bunch of times, power off the device and then power it back on for the new engagements to appear. However, that doesn't always work either.

Very quickly it is taking more and more effort to get the data to sync and display and it seems likely that the sync/restore feature via Dropbox will cease working altogether very soon. However, as things stand now, it's just taking too much effort to get this function to work.
