I just started using Obsidian. What is the best way to use Obsidian both on your phone as well as your PC/laptop? I use it within git and google drive. How can I sync it most easily to my phone as well?
By the way, you can also collab on a vault/folder over GDrive. DriveSync will be able to choose a "Shared with me" folder directly, but on Windows, first go to the web version (drive.google.com) and make a link to the shared folder in your "My Drive". Back in Windows, the link will be in your G:\My Drive folder. You can then mark that folder/link as "available offline" for the best experience. If you open the link in Windows, you'll get the full path to the folder and can then open it as a vault in Obsidian. You should end up with something like G:\.shortcut-targets-by-id\1-BkkGbtKp2342jSMgR7_HdfshNOAG3mg\OurCoolVault
For iOS, the "hard" part is getting the initial git clone, but after that whenever you open the app you can pull/push any changes or set it to automatically do that on a schedule.
To setup a git repo on an iOS device you need iSH[1] but you can delete it the initial `git clone`. The plugin can handle it from there. Make sure to use https and a token that doesn't expire as part of your git clone url. Here is a guide[2]
The only thing to keep in mind is to have a .gitignore that excludes some of .json config files in .obsidian folder as they often cause conflicts. I exclude workspace.json and workspace-mobile.json which just define what tabs you have open on a given device so I think it makes sense to keep that device specific and not commit it.

You could also pay for Obsidian Sync. This has the added benefit of being officially supported and it funds the development of the software.
In general you can use many cloud provider, SyncThing Fork or GitHub.
I wrote about all these options in more detail here: https://bryanhogan.com/blog/how-to-sync-obsidian
The easiest way to sync would be with the official Obsidian subscription, which costs the most amount of money from the options mentioned here.
