Guides
Manuals written looking at the app, not at the brochure. Each one carries the date it was last checked against it, and says what the platform still does not do.
From creating the tournament to players seeing their times on their phone. The whole run, step by step, with the buttons the app has today.
Two minutes, nothing to download from a store: the website saves itself as an app, keeps you signed in, and tells you your times, your court changes and the scores you have to confirm.
