ChorusFit

Project Overview

A Kotlin and Jetpack Compose workout music app that helps lifters jump straight into the most energetic part of a track and keep training without breaking focus.

The Challenge

Regular music apps interrupted workout flow with ads and slow song navigation, especially when I wanted to jump straight to the high-energy part of a track.

The Solution

I built an Android music-player MVP with a clean Compose interface and a save-chorus flow that lets users resume tracks from the chorus instead of waiting for the beat to drop.

Process & Approach

• Scoped the first version around local playback, a focused library view, and chorus-saving behavior.
• Built the interface in Jetpack Compose with dark and light mode support.
• Iterated on the trim-preview flow so the core workout use case stays quick.

Results & Impact

Delivered the MVP and chorus flow within a week, and I am continuing to add features while considering a Play Store release for wider testing.
