**Is your feature request related to a problem? Please describe.**
**Browser:** All functions the same on every device
**Nextcloud app:** Files app features, notifications except for Talk notifications if you have the app, Photos app features except for viewing photos on the map (if you have the Maps app enabled) and face detection and object recognition is also not available in the app, activities are shown in the app but contacts and calendars are only available in the browser or via caldav and carddav which is almost impossible for "typical" users to set up, the profile cannot be customized (can only be done in the browser) or in part in the Talk app.
**Nextcloud Talk App:** Features of the Talk App

Example: A user only uses the file management function, mainly on the mobile phone, so the user has the Nextcloud app. The user wants to change their profile picture for the cloud. The user searches for the function in the Nextcloud app but does not find it. Now the user contacts the administrator, who must answer: The profile picture can only be changed in the browser, or another app called Nextcloud Talk must be downloaded, this app does it.

For people who do not deal with nextcloud, it is extremely incomprehensible why there are all possible functions in the browser but only parts of functions or entire apps that are available in the browser are missing on the mobile phone in the apps.

**Describe the solution you'd like**
One app for all functions (it is essential)
All the functions I have in the browser must also be made available as an app on the cell phone. If Nextcloud really wants to compete with the big market leaders or be an alternative for "simple" users, it needs to be simpler and more user-friendly.
