Build both iOS+Android app from data in shared Google docs spreadsheet

Hi freelancers,

We are a small company specialized in projectmanagement and mangement consulting. For one of our customers we need an app for both iOS and Android displaying data from a spreadsheet.

The data is now shared via a Google Docs spreadsheet, the data is not public so everyone logs in with his own Google account, it's not a public spreadsheet.

We designed a layout and flow that is documented in the attached Powerpoint. The Powerpoint file contains the link to the spreadsheet

The spreadsheet has 3 tabs:

- 1 tab with Overall KPI's

- 1 tab with detailed alarm messages

- 1 tab with detailed availability numbers

Design for the app:

- 1 splash page

- 1 main page showing all data as detailed in the Powerpoint document

We need:

- iOS + Android app that presents the data as described above

- at startup of the app the user has to log in to get access to the Google Docs Spreadsheet

- the app needs to synchronize data when it is accessed; at startup and at activation after switching apps; it is ok to retrieve all data each time, no local storage is needed at this point

- 1 codebase for both apps, because of easier maintenance

- look at the examples provided for our design ideas/requirements; don't deviate too much as we would have to clear this with the customer again

- our planning is to have the completed product ready in 4 weeks

- listing of the app in the App Store and at Google Play; we need help with this as this is our first listing

After this first version is delivered we foresee regular updates as we and the customer work with the app. In the next version we would like to include push messages and possibly some minor updates.

After delivery of version 1 minor changes are going to be done by our intern, delivery of full source code and setup instructions for the IDE and such at final delivery is part of the last milestone.

MS1: working prototype for both iOS and Android - 40% of contract sum

MS2: final working version listed in app store and google play - 40% of contract sum

MS3: at delivery of source code + instructions - 20% of contract sum

Regards, Tony
