TrainWiz

ZEN LABO LTD is an independent software studio based in London. We build calm software — small, deliberate tools for focus, ritual, and intention, designed to respect your attention instead of competing for it.

Our flagship product is TrainWiz, a fitness app that turns workouts into Pokémon: prop up your phone, do real squats or push-ups, and on-device AI counts your reps automatically — no camera footage ever leaves your phone. Every rep feeds a cute pet that gains XP, builds a daily streak, and evolves from hatchling to fully grown as you keep showing up. It's built for beginners and busy people who can't stick with traditional fitness apps: bite-sized daily quests you finish in about a minute, no gym or equipment needed, plus live co-op sessions to work out with a friend. Free on iOS and Android.

Everything we ship follows the same principles: privacy by default (processing happens on-device wherever possible), no dark patterns, no engagement traps — software that helps you build a habit and then gets out of your way.
