As some have showcased on this forum already, I’ve been using iOS Shortcuts to have nice home screen icons straight to a variety of places and actions within Obsidian:
Each of those shortcuts opens an Obsidian URI (I use the Advanced URI plugin, which gives us deeplinks for opening specific notes, creating new ones, running commands, etc).
For example:
-
Open note launches Obsidian into the Quick switcher with the command URI
obsidian://advanced-uri?vault=Spirit&commandid=switcher%253Aopen -
Dreams inbox launches the specific note where I write my dreams every night with
obsidian://advanced-uri?vault=Spirit&filepath=%25F0%259F%258C%2580%2520Ephemeral%252FDreams%2520inbox.md -
New note creates a new note using the Lumberjack plugin with
obsidian://lumber -
Daily note (yellow icon) opens the daily note and puts the cursor on a new item line at the end again with Lumberjack and
obsidian://log.
These are all very simple Shortcuts to set up:
This is tremendously useful already, but there was one further improvement possible - bringing these icons to the lock screen as well, as iOS 16 glance widgets:
I achieved this thanks to an additional iOS app: ShortFlow.
ShortFlow allows us to set up those widgets and make them point to either an app, an existing Shortcuts workflow or a URL.
While I could use my existing Shortcuts workflows, I noticed that doing so first opens the Shortcuts app and then runs the flow. Not ideal. However, since those shortcuts open URLs anyway, I just reused those within ShortFlow:
All that was left was customizing the lock screen to add the widgets:
Et voilà! Lock screen to Obsidian shortcuts! I don’t think it gets better than this 
(Note that ShortFlow supports up to 3 free widgets, and a max of 9 when paying a one time $4.99 upgrade)
