Scan your contract or decode the dealer's offer sheet. Shortfall flags every line that's higher than typical for your state — all on your phone. Buying a car this week? Don't sign until Shortfall reads the paperwork. Car dealers know most people won't study the contract. That's where the extra charges hide. Shortfall reads the paperwork on your phone and flags every fee that's higher than typical for your state. One free audit included, then a one-time $4.99 in-app purchase unlocks unlimited future audits. No subscription. WHAT'S FREE, WHAT REQUIRES THE $4.99 UNLOCK Free, no purchase required: • Your first full contract audit — complete verdict, every flag, full Walkaway Card share • Your first Four Square Decoder round — back-solved interest rate and verdict • Checking Kelley Blue Book trade-in values and saving the numbers — always free, no cap Requires the one-time $4.99 in-app purchase: • Every contract audit after your first • Capturing revisions when the dealer rewrites the numbers at the desk • Every Four Square round after Round 1 (for the same negotiation or a new one) • Saved audit history across all future car purchases HOW IT WORKS Scan the contract with your camera or import the PDF. In about a minute, Shortfall pulls out the price, interest rate, doc fee, warranty, GAP insurance, and every add-on, and compares each one against what car buyers in your state usually pay. You walk into the dealership knowing: • Whether the doc fee is legal (12 states cap it) • Whether the interest rate matches your credit • Whether GAP and the extended warranty are marked up • Whether the monthly payment actually adds up Every flag reads in plain English — "$300 above typical for your state" — not a judgment. You decide what to push back on. STUCK IN THE FINANCE OFFICE? The Four Square Decoder figures out the interest rate from the monthly payment, even when the salesperson "forgets" to write it on the page. Round 1 is free. Capturing each revision they hand you after that requires the one-time $4.99 unlock — so when they rewrite the numbers, Shortfall shows exactly what moved. TRADING IN? (ALWAYS FREE) Shortfall opens Kelley Blue Book right in the app so you can look up your trade-in range yourself. Save the numbers — when the dealer throws out a low offer, you have something to check against. No in-app purchase required for the trade-in tool. PRIVATE BY DESIGN • Everything runs on your phone • No account, no email, no cloud • We don't sell your data because we never collect it Works in all 50 US states. Every benchmark cites its source, and you can check and correct any number Shortfall reads from your contract before it's compared. Pricing: the app is free to download with one free contract audit and one free Four Square decode included. A single one-time $4.99 in-app purchase unlocks unlimited future audits and capturing every dealer revision. No subscription, no recurring charges. Requires iPhone 15 Pro or newer.

Sharper, more honest numbers: • Check and correct any number Shortfall read from your contract — the verdict updates instantly. • The top-line total now counts only what's above typical. A fee below typical no longer hides one above it. • If a scan is too blurry to read, Shortfall says so and lets you rescan or enter the numbers — no empty "all clear". • GAP and service-contract checks measure from a fair dealer price, so a higher charge always shows a bigger gap. • Better state detection near borders (Kansas City, West Virginia) and sturdier reading of fee labels. • Cancel a scan while it's reading; unlock purchases now pick up right where you left off. • VoiceOver reads every verdict card with its rating, text scales with Dynamic Type, and Reduce Motion is respected.
