Rythmic
The perfect combination of a metronome and a tuner.
Overview
Rythmic is a beautifully designed metronome and tuner app for musicians. It combines two essential tools every musician needs into one elegant package with a focus on simplicity and precision.
The Challenge
Musicians need reliable tools for practice, but existing apps were either too complex or lacked the precision required for serious practice. We set out to create an app that:
- Provides accurate tempo and pitch detection
- Has a beautiful, distraction-free interface
- Works reliably in various acoustic environments
Technical Stack
- Platform: Native iOS with Swift and SwiftUI
- Audio: Core Audio for low-latency processing
- Design: Custom SwiftUI components for fluid animations
Key Features
Precision Metronome
Sub-millisecond accurate timing with customizable time signatures and subdivisions.
Chromatic Tuner
Real-time pitch detection supporting multiple temperaments and reference frequencies.
Beautiful Design
A clean, dark interface that looks great on stage and doesn't distract during practice.
Results
Rythmic has been downloaded over 10,000 times and maintains a 4.8-star rating on the App Store. Musicians from beginners to professionals use it daily for practice and performance.
Lessons Learned
- Audio latency matters: Even small delays are noticeable to musicians
- Keep it simple: Musicians want tools that get out of the way
- Dark mode first: Stage and practice room lighting favors dark interfaces
