CamberPro vs Digital Protractor & Level

CamberPro turns your phone into a wheel camber gauge — measure the camber angle of any wheel, check it against a target spec, and know instantly if it's in or out. ■ Why CamberPro reads different from a bubble app Most phone angle apps show you a raw, jittery number that changes every time you place the phone. CamberPro fixes that with two techniques borrowed from real hardware gauges: • 180° flip calibration — measure once, flip the phone 180° on the same spot, measure again. The app cancels out your phone's sensor offset automatically and stores it, so every reading after that is calibrated. • Stabilization window capture — the app watches your reading settle over ~1.5 seconds and only locks in a value once it's stable. No more locking in a number while your hand is still moving. ■ Built for a full 4-wheel session Work through FL → FR → RL → RR with a top-down progress board that shows each corner's status at a glance, color-coded against your spec (in tolerance / out of tolerance). See cross camber (left vs. right difference) instantly — a quick way to spot uneven suspension setup. ■ Vehicle profiles with target specs Save a profile per car with front and rear target camber angles and your own tolerance (±0.2° / ±0.3° / ±0.5°). Every capture is judged against that spec automatically — no more doing the math yourself. ■ What you get • Analog dial gauge + digital readout, motorsport-instrument styling • 180° flip calibration to remove sensor offset • Stabilization-window capture (locks a settled average, not a jittery instant value) • 4-wheel session board (FL/FR/RL/RR) with pass/fail against target spec • Cross camber (left−right) at a glance • Unlimited vehicle profiles (Pro) with front/rear target camber + tolerance • Session history saved per vehicle • Dark and light instrument themes • Works on iPhone and iPad • 8 languages ■ Private by design No account, no upload — everything stays on your phone. Remove ads and unlock unlimited vehicle profiles with a single one-time purchase, forever. Note: CamberPro measures camber angle only. It does not measure toe or caster and is not a substitute for a professional alignment rack. Readings are estimates from your phone's built-in sensors intended as a DIY reference aid — always verify critical alignment work with a qualified shop.

Built for construction workers, carpenters, installers, DIYers, and anyone who needs a clear angle reading. Digital Protractor & Level gives you four clean, high-contrast measuring tools: Protractor, Level, 4 Corners, and Photo Angle. Large readings and controls stay easy to see, and the layout adjusts when you rotate your phone. FREE PROTRACTOR • Read angles with the realistic protractor • Automatic short-edge and long-edge measuring • Clear portrait and landscape layouts • Keep using the basic protractor without a time limit PRO FEATURES — $3.99 ONE TIME • Traditional bubble level with numerical readings • Large 4 Corners bullseye level for surface tilt • Photo Angle: choose a photo and drag a corner and two endpoints to measure the angle between them • Zero and calibrate on any surface • Hold readings while you move • Set a target angle with haptic guidance • Hear measurements spoken aloud • Use the flashlight in dark spaces PHOTO ANGLE Measure a corner, roofline, or drawing in a photo. Reposition all three points, reset the lines, or rotate your phone while keeping your measurement. Photo Angle measures the angle as it appears in the image; perspective can change the real-world angle, so use a straight-on photo. Photos and measurements are processed on your device and are not uploaded by the app. Only the photo you choose is shared with the app through the system photo picker. Photos stored only in iCloud may need an internet connection to open. The basic protractor is free. Unlock Pro permanently for one $3.99 purchase. Existing Pro owners get Photo Angle at no extra cost. There is no new trial, subscription, recurring charge, advertising, or account. Internet access is needed for purchases and restoring Pro.
