Dont buy it

After reading all of the reviews I still bought this worthless app. If you are looking for a call, message, or calendar alert wait until its built into the phone, dont make these guys rich by buying/downloading this. Go to their web site and read their description.

"Currently Apple, Inc does not allow background applications. In order to achieve the functionality listed above you must start the Missed Call application before putting your phone down. There is currently an issue with the 2.2.1 iPhone firmware that causes text message and calendar events to cause applications to sleep. This is a change in behavior from the 2.1 firmware which the application was released on. This causes the visual component of Missed Call not to show but sounds still occur. In order for the application to function normally change the iPhones Auto-Lock value to Never"
