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 ━━━

• 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
