I am working on a concept for both iPhone and Android app. App contains images, text and buttons.
So far everything going well in terms of creative, but I assume there is going to be a big leap into technical part of development soon, so im feeling little bit nervous about that and im asking you for help.
I am using Photoshop to create App screens, buttons and everything… and of course, vector and smart objects within.
I am not sure exact what DPI i suppose to use, 72, 163 or 326…?
However, I do know the iPhone 4 resolution is 640×960 pixels, and I wonder how my PSD document should look like?
Can you guys help me with this new document settings for iPhone first, please:
Width: 640 pixels
Height: 940 pixels
Resolution: 72 ???? pixels/inch
Color mode: RGB Color 8 bit.
Than I would need the same kind of info for Android platform, please.
And if there are some additional things i should know in advance before or after, please give me a hint, I really appreciate!
Thank you!
Cheers!
I am unsure exactly what DPI is best, but I can share my experience so far. I just created my first mobile design comp and tested it on the iPhone at 72 DPI and that is not large enough (for the 4th gen model at least) The 326 setting seems to work for my comp, so that is what I would suggest you try. It seems to be the consensus opinion based on what I have heard in talking to the guys I work with who is a developer.
Hope that helps.
