• Custom Document Icon (large) - 320x320px

iPadApp Icon File Formats:

Items to remember:

• Keep your corners at a 90 degree angle (square not rounded!)
• Do not add shine/gloss
• No transparencies!

There are also other items that one should keep in mind when creating their icon. Color is always a factor! You want your icon to be eye catching and grab the users attention right from the get-go. You will also want to try to avoid using text on your icon - or at least use very minimal text - too much text tends to look busy and can often be hard to read at the smaller icon sizes. Keep your icon crisp by paying attention to detail while at the same not making it overly cluttered and too busy looking!

That's all for this article! Stay tuned for my next one that will talk about launch/default.png screens for your iPhone and iPad applications!

Enjoy!
