Hi I am looking for an app to download ringtones that dose not require a computer, all the ones I have found so far you need one. I have an iPhone 5s if that makes a difference.
As far as I am aware you do indeed need a computer with iTunes to set ringtones. Ringtones offered for download by Apple, I don't know if you need a computer... I generally make my own so I'm not certain on that one. Someone else will chime in with more info, or to correct me.
I've been told Ringtones can be created in Garage Band without a computer, but that it's complicated. So I avoided it. If I need any, I'll just purchase them from iTunes.
