The project requiring a quotation is to build a prototype/proof of concept Apple iPhone App that will also run on Apple CarPlay and can be extended to run on Apple Watch. The App is to use Apple SiriKit with custom intents and vocabulary creating an application that will access an external database using a REST API responding to voice commands and retrieving data which will be spoken to the user. The entire interaction is spoken commands and spoken responses. A full description with examples is in the attached document.
Note that for the prototype the freelancer developer's Apple Developers account can be used. The company's Apple Developer account will be used for the real App. The App will be submitted to the Apple App Store and therefore must conform to Apple guidelines using appropriate Apple tools and frameworks. Subsequent versions may be built for Android to be available from the Google Play store.
Time is of the essence for the development of this proof of concept.
