If you have, or know of, any Bitcoin based cryptocurrency that is offering a Bounty for a mobile wallet app, then I would be glad to be of service.  I've published one for Bongger (Search Bongger Wallet in the Play Store), and  can turn out an app for you pretty quick since I have all the code ready to go.   The app will run on all platforms, including web.   

Post here, or PM me if interested!
