Develop a very simple [login to view URL] app

Dear developers,

I would like to develop a very simple App which must work in Android and IOS, so [url removed, login to view] is the requirement.

In the first phase, the App will only have very basic functionality:

1) Introduction page with 5 sliding windows: in each of these sliding windows, there will be a picture and a maximum of 2 text paragraphs, describing the App purpose and the purpose of 4 products. As an example, please see Microsoft OneDrive v4.16 app - Become Premium sliding windows.

2) Authentication functionality, which will all work by issuing WebAPI calls (so obtain token and token refresh will be supplied by the server): create account, login, logoff, change password, forget password, obtain token, refresh token, handle revoked and invalid tokens.

3) Profile functionality: create profile, edit profile, delete profile. The profile info will be: full name, gender, birthdate, full address, landline phone, cellphone, e-mail address. And picture (crop from picture, upload, show, delete).

4) Notifications functionality: obtain the Registration Token from Google Firebase Cloud Messaging (FCM) and send it to the back-end (by calling WebAPI); receive notifications and show them on the phone tray (show with the received icon); handle the notification priority and time to live specified in the received notification; handle tray click to open the App in the Notification page; create notifications page showing all received and not "expired" notifications, display popup with full notification details when clicking on a notification, delete notification by long pressing the notification and delete it from an option.

Please estimate these efforts and send me your offer.

Thanks in advance.
