For most apps the looks don't really matter to me, so I wouldn't pay just for that. I would only pay for an app if it: - does the job - has no free equivalent that works - saves me a lot more time/money than the cost of the product, or doesn't cost over 20€ (this is my personal threshold, for personal work. I would be fine paying more for something that I would use in professionnal work) - has useful and innovating features (especially if something that has already been made hundreds of times like a music player) - has a good UX - has good documentation/support - has a trial version
