Hi there,
The food delivery app that you are looking to be designed and built for iPhone/iPad will actually comprise three applications or modules (depends upon in what way you want it to be built). Below is the brief of the three applications I'm talking about:
1) Customer's app: This application is used by the customer to browse restaurants and order food.
2) Delivery agent's app: This application is used by delivery agent to mark the location, direct themselves to the required address and acknowledge that the food is delivered to the customer.
3) Restaurant's app: The third app is used by restaurants to accept/decline orders, upload new items, etc.
These three applications should be developed separately so as to avoid confusion between the login/signup of the user, restaurant and delivery agent and to use the API effectively.
I have designed and developed a similar application in the past, thus know very much about the requirements along with the normal workflow. In case your idea is different, ping me and let me know!
I'm online most of the hours, hence you can spot me anytime for the discussion.
Look forward to hearing from you soon!
Regards,
Gaurav T
**NOTE: Final price and time period will be planned post discussing the final details/requirements.
