You can upload your statements and bills into it sure, but for budgeting it will help you as much as a piece of paper will: you can set up a notebook or a template or upload a (in your case register) PDF but have a calculator handy because it’s not a spreadsheet.

Depending on how complex you get it still may work. I could probably move my personal bill tracking method into the Remarkable, but some people expect Mint, which this won’t be.

I was initially worried about storage space for you, but I’ve been paperless almost a decade now and my bills collection is 500MB. So ?? should be fine ??

Can you keep an “INBOX” page or notebook?

Have a quick sentence to jot down? Add it to the inbox page. Continuous pages give you more room, the select and move abilities let you get tour sentence out of the way or put it where it really goes (via cut and paste) easily.

In addition to Quick Notes I keep a normal inbox and a phone inbox, making one new page per new thing.
