Bevel vs Ruler & Digital Caliper

Bevel turns your iPhone's built-in sensors into a pocket workshop of measuring tools: clean, quick, and quiet. No ads. No accounts. No subscriptions. Bevel uses the network for the App Store's billing for the one-time upgrade. We receive anonymous usage stats. FREE, FOREVER • Level: bullseye and torpedo bubble levels with edge readings and calibrate-on-flat • Compass: a smooth rotating dial with true-north support via a declination you set yourself • Protractor: measure an angle by tilt, or drag two arms on screen • Ruler: an on-screen scale you calibrate against a bank card so it reads true • Plumb: check walls, frames and posts are truly vertical • Screen Test: full-screen colours to hunt dead or stuck pixels • Sensor Check: every sensor your iPhone carries, live, and what Bevel reads from each one • Flashlight: a real torch, a full-screen light, and an SOS signal BEVEL PRO, one purchase, yours forever • Metal Detector: sense magnetic fields to find studs, nails and pipes, with a pulse that quickens as you close in • Seismometer: a live vibration graph with peak hold • Altimeter: barometric pressure and relative altitude • Rangefinder: estimate the height and distance of a tree, building or ceiling by tilt, or with the camera sight and a box you tap or draw, calibrated from a height or distance you know • AR Measure: point the camera at a floor, wall or table to measure distances, paths, heights and areas, with a ring that turns green when a surface is found • Vial Level: a glowing liquid bubble in black glass that follows how you hold the phone, roll and pitch together • Every skin and every sound set Tap any Pro tool for a short preview before you unlock it. Pro is a single one-time purchase tied to your Apple Account, so it unlocks on any compatible device you sign in with. No subscription, ever. BUILT HONEST Phone sensors are handy, not laboratory instruments, so Bevel's readings are approximate, and it tells you the truth up front. Not every iPhone has every sensor, so each tool shows at a glance whether your device supports it. On iPhone and iPad the Altimeter asks for Motion & Fitness the first time you open it, and the reading stays on your device. The Rangefinder's camera sight and AR Measure ask for the camera; frames are analysed on your device and never leave it. THE STUDIO PROMISE Bevel is part of the Zone7 utility line: small, focused apps that respect you. Private by design, calm to use, pay once and own it. More at zone7studios.com.

Measure small, flat objects on your iPhone with an edge ruler and two-jaw digital caliper. On supported iPhone models, start with an approximate device-based screen scale. For a physical check, align a ruler with a 20 mm reference on screen. Lifetime access requires a separate one-time purchase and adds repeated measurements and a session workspace: view a result, use it as a reference, and compare the next object. Results and references remain in the current session. TWO FOCUSED TOOLS • Edge ruler with a movable origin and end marker • Digital caliper with two independently adjustable jaws • Magnified contact guide for placing markers at object edges • Fine-adjust controls for small position changes • Reset markers without resetting calibration FOUR UNIT FORMATS • Millimeters • Centimeters • Decimal inches • Fractional inches, rounded to the nearest 1/64 BUILT FOR REAL-WORLD ALIGNMENT Keep a small object flat against the usable screen edge, move the contact points to its edges, and read the result. Switch tools and units as you work. Use portrait or either landscape orientation, and lock orientation while aligning an object. PRIVATE BY DESIGN Measurement values and marker positions are calculated on your iPhone. There is no account, advertising, camera access, or measurement server. Limited privacy-conscious product analytics never include measurement values, marker positions, or calibration data. Calibration and preferences are stored locally. A PRACTICAL SCREEN TOOL Results depend on calibration, alignment, display settings, screen protectors or cases, and the object being measured. Recalibrate after changing iPhone or Display Zoom. For important measurements, compare the result with a known physical reference. Ruler & Digital Caliper is not a certified measuring instrument.
