Unpopular opinion: my $1 store calculator beat my budgeting app at catching a $340 leak
My phone app kept showing I had $340 more left in groceries each month than I actually did, so I started writing every purchase on a notepad and punching it into a $1 store calculator I keep in the car. Turns out the app was rounding up every purchase to the next dollar, and the calculator showed me I was really blowing through my food budget by the 20th. Does anyone else keep a dumb paper backup because the apps keep lying to them?
