TrueLevel vs Pitch and Roll

TrueLevel turns your iPhone into a bubble level, angle finder, protractor, and plumb tool for carpentry, installation, and DIY checks — all with a clean, easy-to-read interface. • BUBBLE LEVEL Place your iPhone on a surface to check whether it is level. The dual-axis bubble responds in real time with live degree readouts. • ANGLE FINDER & PROTRACTOR Use the full 360° protractor display to check an angle. Hold your device against a surface and read the displayed angle for cutting, framing, or slope checks. Lock & Hold keeps a reading visible while you move the phone. • PLUMB MODE Check vertical alignment with a dedicated plumb bob display. Ideal for door frames, posts, fences, and wall installations. • HAPTIC CONFIRMATION Feel a subtle tap when the readout reaches level, so you do not have to stare at the screen. • SAVE & REVIEW READINGS (Pro) Save a reading with a job label, edit it, and revisit your organized measurement history later. Saved records stay on your phone. • DEVICE CALIBRATION Zero TrueLevel against a reference surface with a simple two-step calibration. Results depend on device sensors, placement, case, and calibration. FREE MEASUREMENT TOOLS • Bubble level with real-time dual-axis display • Angle finder with full protractor readout • Plumb mode • Lock & Hold • Haptic confirmation • Device calibration and unit controls TRUELEVEL PRO — CHOOSE YOUR ACCESS • Weekly subscription: eligible new weekly subscribers can try Pro free for 3 days, then the subscription renews weekly at the localized App Store price until canceled • Yearly subscription: billed yearly at the localized App Store price, with no free trial • Lifetime access: a one-time purchase at the localized App Store price, with no trial or renewal Every Pro option unlocks the same saved-work workflow: labeled measurement history, editing, organization, and later reference.

Every inclinometer shows your angle. Pitch & Roll knows your limits. An angle alone can't tell you whether you're in trouble — that depends on your vehicle, your tyres, and the ground under them. Pitch & Roll measures the live pull on your vehicle and shows how much of two limits you're using: GRIP — how close your tyres are to sliding. Set by your tyre type and the surface you're on: tarmac, gravel, rock, sand, mud or snow, dry or wet. TIP — how close you are to lifting wheels. Set by your vehicle's real geometry: track width, centre of gravity, wheelbase, roof load, lift. One glance gives you both readings, a dot against your two boundaries, and a plain sentence: "Slide comes first on gravel." "Tip is your nearer limit — watch the lean." No thresholds to guess. No generic warning angle. WHY AN ANGLE ISN'T ENOUGH 23 degrees is a non-event in one vehicle on dry clay and a rollover in another on wet grass. The same corner that barely wakes a stock SUV can lift a wheel on an RV-boxed expedition truck. Pitch & Roll computes the difference — that's the whole point. BUILT FOR THE MOUNT Calibrate once on level ground (two seconds). Mount the phone at any angle, even turned toward the driver — the mount-yaw dial keeps readings in the vehicle's frame, not the phone's. Remounting doesn't need recalibration. CHANGE SURFACE MID-DRIVE Tarmac ends, gravel starts: one tap on the surface selector and your grip limit updates — with a wet modifier where it matters. Watch the boundary move; that's why an angle can't warn you. FOR EVERY RIG — AND THE ROAD TO THE TRAIL From street tyres on a sedan to mud terrains on a lifted pickup: eight tyre classes, from summer road tyres to studded winters, each with its own grip on each surface. Useful on the drive out, honest on the trail. HONEST BY DESIGN Every reading carries a ~ because every limit is an estimate, computed from published engineering values — not a measurement of your exact tyres on your exact rock. Readings are advisories, not safety determinations. Sudden swerves, bouncing, and obstacles can upset a vehicle below these limits. Your eyes are in charge. Interact with the app only while parked. PRIVATE, FREE, QUIET No account. No ads. No subscription. Motion data is processed on the device and uploads nowhere — the privacy label says "Data Not Collected" because there is nothing to collect. Pitch & Roll. Slide or tip — know which, before the trail tells you.
