Josh Ginter:

Cleartones are awesome. They’re simple notification tones and ringtones made with simple instruments. To me, these are the ringtones Apple would make if they, you know, made better ringtones.

I remember seeing Cleartones years ago, but never jumped on board. For whatever reason, Josh's post convinced me to give them a shot and I'm quite enjoying them now. Most of my notifications go to my Apple Watch, so my phone is usually silent, but sometimes I do need to use audible notifications and these just make it a little more delightful.
