I have been sold on app with clean sharp images as the background with clean strong lines/text/icons.
have tried a few different ones that have worked but have now after almost finishing the app found one that works the best.
I really like the coffee beans as the image is light and the existing design elements look really good and achieve the look i was designing too.
Throughout i am using a blue/aqua colour box as the header and for the logo to sit on top. this was done to emphasise the logo and provide some brightness to the app but with the new background i have decided to remove it. please let me know which one you like better
