Andro Ruler

Andro Ruler — Ruler, Spirit Leveler & Precision Measuring Tool The two measuring tools you reach for most in daily life — a ruler and a spirit level — are now together in one clean, touch-friendly app. Turn your Android device into a precise digital ruler and an accurate leveler in seconds. ━━━ MEASURE LIKE A REAL RULER ━━━ • Choose inches or metric (centimeters / millimeters) to match the units you use every day. • Fine, high-resolution scale marks let you measure small objects with confidence. • Fine-tune your measurement precisely with the track ball (or touch) for maximum accuracy. • Multi-touch support lets you pan, zoom, and inspect the scale exactly where you need it. ━━━ ADJUST ON-SCREEN PITCH FOR PERFECT ACCURACY ━━━ No two devices are identical, so Andro Ruler lets you correct the on-screen ruler when its pitch isn't accurate: 1. Lay a real scale against the side of your device, next to the on-screen pitches. 2. Tap the button that brings up the adjustment controls. 3. Use the left and right buttons to fine-tune the on-screen ruler's pitch until it lines up exactly with the real scale. Your ruler is now calibrated to your specific hardware — measure with confidence. ━━━ SPIRIT LEVELER WITH TWO PRO DISPLAY MODES ━━━ • Degree mode: precise H (horizontal) and V (vertical) tilt readings shown in degrees. • Graph mode: center the bubble on the crosshair for fast, intuitive leveling. • One-tap calibration: calibrate to your current surface in 3 seconds. • Tap to hold: touch the leveler view to hold a value in place. • Optional beep: a sound plays when the level is reached. • Reset leveler calibration back to default whenever you need. ━━━ MAKE IT YOURS ━━━ • Change ruler and text colors to match your style or your project. • Reset ruler adjust settings to default with a single tap. ━━━ FEATURES AT A GLANCE ━━━ • Inches + metric (cm / mm) unit support • Adjustable ruler pitch — calibrate against a real scale • Digital spirit leveler in degree or graph mode • Multi-touch support • Track ball fine-tune for precise measuring • Customizable ruler and text colors • Leveler calibration, tap-to-hold, and level-beep • One-tap reset for both ruler and leveler • Lightweight, fast, and intuitive ━━━ A NOTE ON PRIVACY ━━━ All permissions used by this app are used only for displaying ads.
