See attached screenshots or app store link for current app workflow.
For this new design I want to simplify and really create a clean, 2D look using a white, grey, black and maroon color palette. You can use different shades from what is in the Illustrator files.
The main entry point into the app is the center focus tab bar. This needs an icon as does the other two tab bar menus. Also need icons for the play and "more" buttons (the arrow) and the about, free and premium functions. The play button should have a pause/stop icon while playing. The arrow brings up a menu with options to save, tweet, like, etc.
The center focus screen should have a dial / knob design with 10-12 points around it that the user can "dial" and filter the ringtone list below. They can also use secondary filters "Free" and "Premium". I'm open to interpretation of where the free and premium filter widgets are placed and how they look. Same for the knob and the screen in general. If you have a UI concept that is really great and works better please present it.
Examples of filters are "hip Hop" or "Orchestral" or "Mellow". The name will be displayed below the dial, once a filter is selected.
I've uploaded Illustrator files so you can play with the knob and swoosh from the Tonecrusher logo.
