As a dedicated developer working part time and going to school full time, I can't be at my home computer whenever I think of new ideas or new ways to go about designs.
That's why Hello is very useful on the go.
Without Hello, it would be a huge hassle getting on some temporary computer and setting up your development environment to be identical to your home computer's environment. Not to mention you couldn't even do that straight from your phone.
Similarly, you wouldn't be able to see real-time results as you upload graphics and make code changes -- your friends would have no idea what updates you've made.
Luckily for you, I've been there -- having a great idea, but no way to try it out until I got home several hours later.
Whether you're on the go, have a team across the country, or an individual seeking money and happiness through starting your own company with an app, World of Hello is perfect for you.
