Mr Z

An AI Coach in Your Browser, Why and How

Francesco Zen, founder of ZTraining · Last updated June 19, 2026

Why not a dedicated app

A dedicated app you have to download starts as a novelty and, for most people, ends up feeling optional within weeks — one more icon competing for space, one more account to remember. A webapp skips that decision entirely: there's nothing to install, so there's nothing to delete.

"The first app you delete when you need space is the one you'd already filed away as optional. Mr Z was never something to delete — there's nothing installed to begin with."

What that means in practice

Running as a webapp means Mr Z is never competing with a dozen other app icons for attention, because it was never one of them. Open your browser, or tap the icon if you've added it to your home screen, and it's there — the exact day motivation dips, not buried three screens deep or already uninstalled.
