Looking to develop an app for iOS and Android, which would require the ability for core features to work offline (no connection), but also to synchronise data when connected to ensure updated.
It would need the ability to
1) Login (connection to existing SQL database) - once logged in retain details on device so no need to login each use
2) Key Functions
2.1) A members directory - searchable by company name/contact name/country (needs to work offline), this would then give a listing of matching Companies. Click on a company for a profile which would include Company Name, Country, Address, Telephone Numbers, Fax, Email, Description of Business Contacts and their contact details. This is stored in Microsoft SQL database and we can provide a webservice API for connection. Approx 250 companies.
Needs to work offline (i.e. no connection).
2.2) Chat feature, select from the entries in 2.1 and be able to send and receive messages from them (basic texting/whatsapp type solution). Obviously when online messages received, but options to possibly store and sync messages when reconnected.
We could supply the design concept in a PSD format (not developed yet), or happy for this to be quoted also.
If you can let me know if this is possible, the timescale and costs, that would be appreciated. Also ongoing maintenance arrangements.
