f you don't want to use public clouds or if you care about your private photos and documents, Nextcloud is the solution for you. It runs on a regular LAMP server and there are several apps for mobiles and tablets.
Nextcloud includes common cloud features:
- Photo gallery
- E-mail client, calendar and address book (e-mail server installed separately)
- Project planner
- Possibility of sharing
- And there are many more modules to install
I personally use the following mobile apps:
- Nextcloud Talk
- Nextcloud Notes
Nextcloud saves notes in markdown format, which has become the standard for developer documentation.
