Your Alarms is a multialarm applications designed mainly for OS 9.1 S60 devices, which do not have this functionality implemented with native clock applications, but it should also work with other 3rd edition S60 devices as well

This version is definetely a beta, I have tested that it works, but just with few devices, anyway, this application is also self-signed, which means that it can not have WriteDeviceData capability, and because it is missing it, you can not modify alarms made by any other application, thus you should first use the normal clock application to delete all alarms, and then use this applications to re-set them.
