I am about to design an IOS 8 app for the very first time.
I've been a designer for 5 years now, both on Photoshop and Illustrator, but I never got the change to design an app. I am looking for some guidelines.
My questions are: Which program should I use? Photoshop or Illustrator? I am much more comfortable on Photoshop, but I am afraid of the sizing. Which brings me to my next question, which canvas size to pick, iPhone 4, 5, 6 or 6+? Or maybe a design for each size (same style though)?
What to use? Anything you are most familiar with, Illustrator, Photoshop, Pixelmator or any other app you can run, and better - on Retina display.
You should perform a lot of searching and planning ahead of placing any single line on your graphic software - you deal with Apple and should clearly understand what they want from you and what you want from the users.
