Tired of Finance Apps That Waste Your Time?
You're not trying to figure out where your money went. You already know how to manage it. You just want to see if you're on track.
Track Every Coffee Purchase
"Spend 30 minutes a week categorizing every transaction just to see a number you already know."
Hand Over Your Bank Login
"Trust a third party with credentials to every account you own. What could go wrong?"
