Multiple versions of same app confuses unwary shopper

I bought a super similar app with the same name. I wanted to re-download it and found this app and thinking it was the same one accidentally paid for a new app with identical functionality. The app producer has different names but Im convinced its the same guy or company. This app itself is decent although it should be noted it doesnt allow you to set the background color. It should be noted though that this guy needs to be looked into by Apple and I hope nobody else gives him money.
