Moove
A minimalist, offline-first workout tracker with AI coaching built-in. Designed for people who want to stay consistent without the bloat.
The Problem
Most fitness apps are bloated with social features, paywalls, and subscription tiers. I wanted a workout tracker that was fast, worked offline, and didn't try to upsell me every time I logged a set.
The Solution
Moove is a personal workout tracking PWA built with React, TypeScript, and Tailwind. It's offline-first, installable on any device, and includes an AI coach powered by Claude.
