[App page](https://appshunter.io/ios/app/helix-tuner/id1444576708)

**Currently charting:** #193 Top Paid · Music (US App Store)

This app offers a novel approach to instrument tuning by visualizing sound as an interference pattern. It avoids pitch detection, instead creating an optical illusion of motion that indicates sharpness or flatness, appearing stable when in tune. This method is highly resistant to background noise and harmonics, providing clear tuning information even in noisy environments.

**Highlights:** Visual interference pattern tuning, No pitch detection, Optical illusion of motion for tuning, Stable visualization when in tune, Resistant to background noise, Useful in noisy environments

**Features:** macOS Compatibility

**In-app purchases:** none
