Digital Level & Angle Finder

Use a supported phone or tablet as a practical digital level and angle guide. The tool displays pitch and roll, bubble-style level feedback, angle status, zero calibration and a hold/freeze mode for checking CCTV brackets, satellite mounts, solar frames and other installation surfaces.

Start and calibrate

Place the phone against the surface or bracket you want to check, then start the sensor. If you want to measure relative to the current surface, tap Calibrate zero.

Important: This is a practical phone-based guide, not a certified surveying instrument. Phone cases, magnets, uneven device backs, sensor quality and mounting position can affect readings. For structural, electrical or safety-critical alignment, confirm with the appropriate professional measuring tool.

The bubble moves opposite the phone tilt. Bring it toward the centre crosshair to level the surface.

How to use it

Use the phone as a quick installation angle guide.

Keep the same edge or face of the phone against the object during the measurement.

01Remove interferenceRemove a thick or uneven case if it prevents the phone from sitting flat on the surface.

02Start the sensorTap Start sensor and approve motion/orientation access if your browser asks.

03Choose the toleranceUse ±0.5° for tighter checking, ±1° for normal mounting and ±2° for rough alignment.

04Calibrate when usefulPlace the phone on your chosen reference surface and tap Calibrate zero to measure relative angle from that position.

05Watch pitch and rollPitch shows front/back tilt; roll shows left/right tilt. The exact axes depend on how you hold the phone.

06Centre the bubbleMove the mounting surface until the bubble approaches the centre crosshair.

07Freeze the valueTap Hold reading when the phone is in position so you can remove it and read the value safely.

08Use the right final toolFor dish elevation, solar structures or precision work, confirm the result with the bracket scale, inclinometer or proper level when required.
