Drag Racing Time Tracker
An iOS and Android app to predict and log drag race times using real-world data.
Overview
A mobile app built with React Native and Expo that helps drag racers log race data and predict future times based on their historical performance and environmental conditions. Designed for simplicity, accuracy, and real-time use at the track.
The Problem
Racers lacked a lightweight, purpose-built tool to track and analyze performance. Existing solutions like spreadsheets or manual notes were time-consuming, inconsistent, and not optimized for mobile use at the track.
My Role
I led the full technical design and implementation of the app. This included frontend development, database architecture, authentication, time prediction logic, and camera-based time slip scanning. I also built the logging system for weather conditions per lap to improve accuracy.
The Approach
- Built with React Native + Expo for fast cross-platform deployment
- Integrated Firebase for cloud-based data storage and user authentication
- Implemented time slip scanning using the device camera and OCR for quick data entry
- Logged weather conditions per lap, integrates with OpenWeatherMap API
- Designed a predictive model that uses historical ETs, reaction times, and logged weather to estimate future performance
- Focused on clean UI and fast input for use during real-world race events
The Outcome
The app is actively being developed.
