Trilium (server edition) has a mobile web frontend which is optimized for touch based devices - smartphones and tablets. It is activated automatically during login process based on browser detection.
Mobile frontend is limited in features compared to full desktop frontend. See below for more details on this.
Note that this is not an Android/iOS app, this is just mobile friendly web page served on the server edition.
Mobile frontend provides only some of the features of the full desktop frontend:
Trilium decides automatically whether to use mobile or desktop frontend. If this is not appropriate, you can use ?mobile
or ?desktop
query param on login page (Note: you might need to log out).
You can alter the behavior with scripts just like for normal frontend. For script notes to be executed, they need to have labeled #run=mobileStartup
.
