Only for iPhone

$2.99

iPhone

Am I over my lease miles? Enter an odometer reading and see pace, projected overage in dollars, and a home-screen widget. $2.99 once — no ads, no subscription. Leased a car? Then you have a mileage budget — and the bill for going over arrives at the worst possible time. OverUnder tells you, at a glance, whether you're ahead or behind your lease's mileage pace. Enter your odometer when you think of it. The app does the rest. ONE NUMBER THAT MATTERS "896 miles under pace" — that's the whole story, on the home screen and in a widget you never have to open. SEE THE BILL BEFORE IT EXISTS OverUnder projects your lease-end mileage from how you actually drive and prices the overage in dollars, not abstract miles. PLAN THE ROAD TRIP FIRST The What-If tool shows exactly what 2,500 more miles would cost before you commit. BUILT FOR REAL LEASES Start tracking mid-lease — two numbers from your lease agreement and everything computes correctly. Your odometer at signing is always your baseline. RESPECTFUL BY DESIGN No ads. No subscription. No account. Pay once. Your data lives on your iPhone, backed up privately to your iCloud, and exports to CSV/JSON anytime. Track multiple vehicles, set gentle reminders on your schedule (off by default), and know — always — where your lease stands.
