I liked my old iPhone "Harp" alarm tone, so found a copy, lowered it a little bit and added to my phone. The volume difference on maximum on the phone is now hugely improved. I guess we'll find out Monday morning! Thanks to DaveR12 for the suggestion, I was able to lower the volume very easily using the Gain, on the right hand side of the track once loaded into the Audacity (for those that want to use their own tracks). I have attached mine, it may be of use to you.
