Obsidian is a great tool for collecting ideas.

I use it mainly for the following reasons:

• Research
• Collecting information
• Saving some spontaneous ideas

Depending on my actual situation I prefer to use my laptop or my phone.
To always have access to my vaults, regardless of the device I am using, I need to sync the data between my devices. For that purpose Obsidian provides the Sync Plugin. But for this plugin they charge you 4$ a month, which I don't want to spend, if there is another option.

I found a solution which meets my requirements:

• Crossplatform availability: Linux, Windows and Android
• No manual work: no downloads, no copies, no nothing
• free to use

What I use now:

• Syncthing-fork on my android phone
• Syncthing on my windows and linux machine
• Shell script to backup the data in a git repository

Setup:

• Install syncthing on the devices you want to use Obsidian
• Create folders on every device to store the Obsidian files locally
• Linking the devices using the QR code
• Share the folders (also using QR code)
• Copy your vault into the new directory and open it in Obsidian
• optional:
  • create a git repository in your Obsidian directory and backup the files to your github account
