Fast, tactile interfaces
Native apps with fast feedback, clean architecture, and interfaces that feel deliberate on the device.
Original iOS apps for focused learning and serious play.
Polyphony Labs designs and builds mobile products for iPhone and iPad. We use native iOS, LLMs, on-device intelligence, Core ML, and computer vision where they make the experience more useful, more responsive, or more memorable.
Software with craft, tempo, and intent.
The studio develops original apps where learning, play, and useful intelligence meet. We care about the feel of the loop: the first tap, the next action, the feedback, the return visit, and the moment the product gets out of the way.
Useful intelligence
LLMs, on-device models, Core ML, Vision, and analytics used only when they sharpen the product.
Progression that earns attention
Progression, difficulty, feedback, and reward treated as product architecture, not decoration.
First product
Piano education app
Our first product is an iPhone and iPad app for piano students: a calmer way to start daily practice, repeat the right work, and understand progress without turning music into noise.
