You can easily add columns and build a board through your mobile device without having to use the web platform!
Open your board and next to your board and scroll towards the right of your screen.
You will then see a + icon exactly like on the screenshot below:
When you click on it, a new window will open with the different column choices. The choice of column is the exact same as on the monday.com web and desktop versions.
You have to select the type of column you would like to add by clicking on it. Once done, press "create" and you have your new column :)
