Development of an alert app

We are looking for a developer who creates an app (Android and iOS) for our web project.

It should be able to:

- Login into our web application (backend available)

- Transmit push token into our backend (backend available)

- Receive push notification and play individual notification sound on max volume in any case (even if phone is silent)


A user should be able to log in. The login should be forwarded to our server and you will get a json response with the name of the user and id if login was successful. Then the app should send the FCM token and user id back to our server, so we know which user uses what device.

If a notification to a device is triggered by our software, its forwarded to FCM and sent to the device. Once the notification is received by the devise it should alert the user by playing an individual sound on maximum volume (even if the phone is set to silent) and vibrate.

Please contact me for further information
