One of the well-known note taking apps is Evernote. You can look at their site to see what it does:
It's nice for things like business card scanning, receipts, remembering your bank account numbers.
But I find the best use for it is for things like gaming. I can store images and sketches of base build designs. Multicolored tables. I can even drop a full spreadsheet for the tougher games like Football Manager. That way there's no linking and sifting through Google Drive spreadsheets.
