Android / iOS PhoneGap based app - open to bidding

[login to view URL] [login to view URL] * purpose of the app is to display various info pulled from one or more WordPress sites via a custom JSON endpoint in textual and graphical manner * in many ways it's similar to MailChimp's app, but quite simpler - [login to view URL] * app is read-only; only time when the user sends/writes some data is when a new site is added * on the first run the user is prompted to add the first website to the app by entering the URL to the API endpoint and a secret key generated by the website (screen #1 on wireframes) * once the site is verified and added he can proceed to look at the data/stats pulled from the site * data will be represented by graphs, charts, tables - those are generated on the server and just appended to some DIV in the app * all those reports will be divided into abot 5 screens * user can add more than one site to the app * apps can be removed and edited * only one site can be viewed at a time - no data mashup (maybe in v1.1) * we also need an info screen with copyright and similar static text * all data processing that can be done on server-side, should be done there * we have full control over the code on WP sites so customizations are not an issue * data exchange format is JSON * if possible jQuery mobile should be used, but if necessary other JS libs will be ok * phones are the primary devices; tablets secondary - if possible a different UI should be used for tablets * permissions needed from the phone: store local data, access internet * CSS UI framework should follow Google Material Design guidelines * we want as little custom JS/CSS as possible! if your lib doesn't have some UI component we'll work around it rather than create it from scratch
