About

CamberPro

Read full description

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.
