Need to develop a mobile app, both in adroid and ios, with these features:
1) Page to create an event.
Event will have 8 form fields: normal, date picker, time picker
2) Page to display the event
3) Invitation page: we want to send the invitation of the event by email, messenger and whatsapp. We can send a link, if user clicks the link, we have 2 cases:
a) user has the application: it opens a page to reply at the event invitation
b) user doesn't have the application: opens a page in which suggest to download it, if skip download it opens a web page in which will reply to the event. We develop this part the web page by ourself, in php. App developer should just create the app in order to read the database and display it, as point 4.
4) Page to read the status of invitation from point 3. Accordingly to reply of the users, display 4 kinds of status.
We provide the graphic for the app in psd.
