Angle Finder Pro – Ultimate Digital Inclinometer & 3D Level Suite

Turn your smartphone into a high-precision digital measurement workstation with Angle Finder Pro. Engineered for
carpenters, handymen, plumbers, roofers, fabricators, and DIY enthusiasts, this comprehensive 6-in-1 measurement
suite delivers instantaneous, sensor-calibrated pitch, roll, and angle calculations on any job site.

Whether you need to true up frames, calculate complex roof pitches, align pipe joints, or measure remote angles via
camera, Angle Finder Pro replaces multiple bulky physical tools with calibrated digital precision.

6 Professional Measurement Tools in One App

1. Live Tilt Meter & 3D Bullseye Spirit Level
• Real-time angle tracking with dual selectable scales: 90° Quadrant or 360° Full Circle.
• Automatically transitions into a fluid 3D Bullseye Spirit Level with precision target rings and center-lock
indicators when laid flat.
• Features Target Angle setting with acoustic beep guidance, instant 0° Tare referencing, and volume key freeze
functionality.

2. Photo & Camera Protractor (Goniometer)
• Measure angles directly on live camera feeds or imported gallery photos.
• 3-node vertex alignment with a corner magnifying loupe and fine-adjustment direction buttons for pinpoint accuracy.
• Save and export annotated photo records directly to your device or share them instantly.

3. Relative Angle Meter (Pipe & Joint Alignment)
• Measure the precise angular difference between two separate planes.
• Place your device on the first surface to lock the reference plane, then transition to the second surface to view
the real-time relative delta and inner complementary angle (180°).
• Includes a dynamic 3D hinge joint visualization and balance tracking bar.

4. Roof Pitch & Slope Ratio Calculator
• Advanced slope analytics with an interactive 3D extruded triangle visualizer.
• Instant automatic conversion between slope percentage (%), roof pitch ratio (X:12), vertical rise per meter
(m/m and cm/m), and horizontal run.

5. Precision Digital Compass & Heading
• Built-in magnetometer compass delivering smooth azimuth headings in degrees and cardinal directions (N, E, S, W).
• Styled with a brushed metal bezel and responsive orientation tracking for layout and site alignment.

6. 3-Axis Independent Chassis Calibration
• Eliminate sensor offsets and physical chassis variables caused by thick phone cases or camera bumps.
• Guided 2-step 180° opposite-pole calibration routine for all three device orientations: Flat (back), Upright
(portrait), and Sideways (landscape edge).

Pro Features & Customization

• Acoustic Proximity Assist: Auditory pitch cues guide you directly to your target angle without watching the screen.
• Hardware Button Freeze: Instantly lock active readings in tight or blind spots using physical volume buttons.
• Custom Gauge Themes & Needles: Personalize your interface with professional themes (Classic Pro, Tactical Dark,
Industrial Hi-Vis, Blueprint, Vintage Brass) and tailored needle styles.
• Offline & Privacy-Focused: Operates completely offline on remote construction sites with no intrusive tracking.
