No matter how useful an app is, it's useless until it is branded.

It's unfortunate, but it's the hard truth: Users are drawn to beautiful software. It's silly to think that a homeowner would spend countless hours making sure the structure of the house is perfect, then not paint any walls or do any interior design — why should your app be the same way?

Take the time to create something that's as beautiful on the outside as it is on the inside. (If it's a huge mess on the inside, just put a bunch of gloss on the outside an no one will ever know, right?)
