I rebuilt Gymcade because I kept quitting other fitness apps. They all felt like spreadsheets. So I turned workouts into a progression system: levels, XP, and unlocks — like a game. 🎮 New in 2.0: • No ads • Level-based progression • Unlock full app after Level 5 • Retro-style motivation Would love honest feedback — especially if you’ve struggled to stick to fitness apps.

I built this because I wanted a Kanban todo list that works the way I think — keyboard first, minimal, and Vim-inspired. This extension lets you manage tasks in a simple Pending / Complete board, navigate entirely by keyboard, and edit notes using Vim-style workflows. It supports QWERTY and Dvorak layouts and stores everything locally in your browser. No accounts, no cloud, no tracking. If you're a developer or keyboard-first user, this was built for you. I’d love your feedback.
