About

Flagfall

Features
Read full description

Flagfall is a chess clock built for real games — at the club, at a tournament, or across the kitchen table. TIME CONTROLS • Fischer increment — time added after every move • Bronstein delay — time spent is given back, up to the increment • US delay — the clock only starts counting once the delay has elapsed • Byo-yomi — main time followed by periods, for go and shogi • Multi-stage FIDE controls — 40 moves in 90 minutes, then 30 minutes, with a 30-second increment from move one • Asymmetric time — give one player a handicap BUILT FOR THE TABLE The whole half of the screen is the tap target, not a small button. In table mode the top panel rotates 180 degrees for the player sitting opposite, and each side sees the opponent's remaining time the right way up. The screen stays awake for the entire game. Your settings and the game in progress survive closing the app — reopen it and the clock is exactly where you left it, paused. ACCURATE BY DESIGN The clock never decrements a counter on a timer. Remaining time is derived from timestamps, so a backgrounded app, a late frame or a locked screen cannot make it drift. NO ADS, NO ACCOUNT, NO DATA Flagfall makes no network requests. It works entirely offline, collects nothing, and contains no advertising or tracking whatsoever. There is no account to create and nothing to subscribe to. Available in English, French, Spanish, German, Italian, Portuguese, Dutch, Polish, Russian, Turkish, Japanese and Chinese.
