Case Study: RepQuik — Fitness Score Logger PWA
RepQuik was built to solve a personal frustration: every popular fitness app is bloated, social, or both. The goal was minimal — log what you did, see your progress clearly, keep your data private. No social feeds, no streaks that gamify your training, no ads. Just your numbers, fast.
The Problem with Most Fitness Apps
Apps like MyFitnessPal and Strava are feature-rich but optimized for the broadest possible audience. For strength training specifically — where you track personal records and score progressions across exercises — they're overcomplicated and slow. RepQuik was an attempt to build what athletes actually want: a fast, private, score-focused logger that installs like an app without requiring the App Store.
MVP-First Development
RepQuik demonstrates the MVP methodology we use for all client projects. Version 1 had three features: log a score, label the exercise, see your last five entries. That's it. Real users used it, gave feedback, and directed what got built next — progress charts, exercise categories, and data export came from user requests, not assumptions.
Key Features
- Exercise score logging with a fast, friction-free flow
- Progress visualization via Chart.js — see trends per exercise over time
- Installable as a PWA — add to home screen on any phone, works offline
- Privacy-first: data stored client-side by default, no account required
- Lightweight state management with Zustand, no over-engineered store
- Polished micro-animations with Framer Motion throughout
