I love apps like this. I currently use Numi daily for running financial-related tracking and scenarios. It has a few annoying UI quirks, so I'm super open for alternatives (especially with cloud syncing).

I played around with porting my Numi sheets over, and the only thing that's tripped me up so far is using underscores as numerical separators, eg: 1_000_000 for 1000000. All my Numi values are written this way, so that's my only feature request. I guess I could just use commas in this context.

Great work!

Edit: And dark mode :)
