👋 Hey Product Hunt! I'm Min, the solo maker behind Sonobender. Sonobender is a touchless musical instrument for iOS. You stand in front of your iPhone camera and use your hands to control pitch, volume, and mood – no tapping or swiping required. 🎵 What it does • Tracks your hands in real time to control sound • Lets you choose from 45+ synth-style waveforms • Adds Aurora-inspired visual effects that react to your playing • Runs on iPhones with iOS 17.6+ • Starts free, with extra sounds unlocked through ads or in-app coins 🧠 Why this app exists Theremins are magical but rare and expensive. Sonobender tries to capture that feeling using only a phone, so anyone can experiment with sound even without music lessons or gear. 🛠 Under the hood • SwiftUI for the interface • Vision framework for 60fps hand tracking • Custom audio engine for synthesis • Metal-powered rendering for the visual effects 🙏 What I'd love feedback on • Is the first session easy to understand? • Do the sounds feel expressive enough? • How does performance feel on your device? • What would make this more fun or more "musical" for you? Thanks so much for taking a look and for any comments you leave. Happy to answer technical questions, UX thoughts, or crazy feature ideas. 🎶
