A high-performance iOS app designed strictly for threshold pace management. Brutalist analytics for distance runners who care about data, not social feeds.

The Concept

Most running apps are cluttered social networks. Redline strips away the noise. It is purely an analytical engine designed to measure, categorize, and execute threshold training protocols with absolute precision. The visual language needed to reflect the intensity of threshold running.

"Built for the red zone. No social features. Just cold, hard pace metrics."

The Execution

Built completely in React Native with strict TypeScript schemas to ensure state reliability during intense workout intervals. The theming revolves around high-contrast typography, making it legible even when you are sprinting and glancing at your phone.

The Outcome

A reliable daily driver for serious runners. It's an exploration in focused utility—eliminating the unnecessary to achieve a single task flawlessly.
