My Scale Navigator

Hello App Review Team, This app does not require an account or sign-in and operates completely offline. To properly review the core hardware-dependent features, please follow these steps: 1. Acoustic Dictation & Triad Trainer (Microphone): The app uses the microphone for real-time instrument pitch detection. Since you may not have a physical guitar or piano available, you can test this feature by humming a clear, sustained note directly into the device's microphone, or by playing a chord from a virtual web piano on a nearby computer screen. The app will process the audio locally and highlight the corresponding notes on the UI. 2. Optical Chord Scanner (Camera / Photo Library): To test the OCR feature, please point the device's camera at any monitor displaying a standard musical chord sheet (e.g., from a website like Ultimate Guitar), or select a screenshot containing chord letters (like C, Am, G7) from the gallery. The app will extract the text tokens locally. All audio and image processing is performed entirely on-device. No data is collected, saved, or transmitted to external servers. Thank you.
