Conference App - Australasian Podiatry Conference

We are looking to have a phone and tablet app created for use at our biannual conference in June. This needs to be easy to use and updatable via an content website. The main features we’d like it to include are: - Large portions of text in a readable format - A personalised calendar drawn from a list of events - A map - Ability to rate the speakers at the conference - Notes function We are still unsure as to the more detailed specifics we'd require for this app and would like to discuss functionality and costs with relevant bidders.
