This guy is hilarious. I actually laughed reading this line: "Every time I'll get a payment notification it's gonna feel like stepping on a lego" Anyway FWIW it's good and not bad that you found a successful competitor doing what you wanted to do. It is not the end of the line rather somebody else has validated the idea for you. The only time you should actually worry is when you can't find one single competing product to what you're building. BTW as you put it that their app is slow buggy, there seems to be a lot of room for improvement and so it's still not too late and maybe time to outshine your competition and eat/share their lunch.
