Stop paying for alignment checks. Your iPhone already has the sensors. AXL turns your iPhone into a precision alignment tool. Hold it against each wheel and against your chassis, and AXL reads toe, camber, and how your rear axle actually sits on the car — the same angles a shop checks, in your driveway, in minutes. Why it matters Bad toe eats tires. A few tenths of a degree off and you're replacing rubber months early, or driving around with a pull you've learned to ignore. AXL shows you exactly where you stand, so you know whether that's a real problem or nothing to worry about — before you spend money finding out the hard way. How it works Three quick captures per wheel, walked in order: centerline, toe, camber. AXL tells you when each reading has settled and moves you to the next spot automatically. A full pass — all four wheels — takes just a few minutes. What you see Toe and camber for every wheel, plus front and rear axle totals How your rear axle's thrust line compares to the true chassis centerline A 3D view that exaggerates the angles so small readings are easy to see at a glance — the numbers on the cards are the real measurement Color-coded results: green means straight, yellow means it's worth adjusting, red means it's wearing your tires right now Track it over time Save tests to named vehicles, add a note like "before adjustment," and pull up any past test later. With two or more saved visits, AXL shows you exactly what changed — every wheel, every axle, side by side. What you need Any flat-sided iPhone case works. For the most accurate readings, our free 3D-printable case design (Soon available on our website) holds the phone perfectly flush against the wheel.
