I propose you to develop a web app using HTML5, PHP,JQuery Mobile, with user frontend and administration backend.
The feel and look will be like a mobile app but executed from the web browser of your touch-screen, and it could be also be executed from mobile devices, like iPhone, iPad, Android, Blackberry,etc. then it will run from the mobile device web browser, no need to be downloaded any app from anywhere.
The administration backend is needed to update the information to be shown on the app.
Please feel free to contact me if you need more information about my proposal.
Thank you
