Azimuth Focus Assistant

Azimuth Focus Assistant is a professional lighting utility designed for ground focus, beam setup, and fixture angle checks. Enter fixture height, horizontal distance, beam angle, and target height. The app calculates the required focus angle, real throw distance, beam diameter, projected footprint, and practical setup values for stage, studio, event, theatre, and architectural lighting work. The app is designed for fast on-site use on both phone and tablet layouts, with a dark interface, large readouts, and direct controls for adjusting target height and beam angle. Key features:

• Focus angle calculation from fixture height, distance, and target height
• Real throw distance and beam diameter readouts
• Beam footprint and projected floor coverage
• Beam preparation panel with configurable preparation height
• Horizontal and vertical beam dimensions for setup at floor level
• Metric, imperial, or automatic measurement system
• Optional gobo reduction factor for estimating image projection area
• Visual geometry diagram with beam cone, floor marks, target height, and human reference
• Adjustable target height and beam angle controls
• Device level mode for checking the real fixture angle
• Target difference readout for aligning the fixture to the calculated angle
• Sound, vibration, and visual flash feedback when the target angle is reached
• Switch to disable visual alignment flash when needed
• Phone and tablet optimized interface
• Built-in language selector with broad multilingual support Azimuth Focus Assistant is designed for lighting technicians, designers, operators, and production teams who need a fast and repeatable way to aim fixtures, prepare beams, and understand projected coverage. No account is required. The app runs locally on your device and only uses motion sensors when the level tool is active.
