## What is Orchestra String Tuner?

String Tuner is designed for open-string tuning on violin, viola, and cello.

Supported open strings:
• Violin: G3 / D4 / A4 / E5
• Viola: C3 / G3 / D4 / A4
• Cello: C2 / G2 / D3 / A3

Key features:
• Real-time pitch detection using the microphone
• Adjustable A4 reference: 440 / 441 / 442 / 443 / 444 Hz
• Reference tone for every supported open string
• Designed for iPhone and iPad
• English interface designed for musicians worldwide

Use it before individual practice, orchestra rehearsal, or ensemble preparation. Microphone detection stops while a reference tone is playing, preventing the app from measuring its own output.

Microphone audio is used only for on-device pitch analysis. Audio is never recorded, stored, transmitted, or uploaded.
