A real chess clock, built for real chess players. Most apps stop at Fischer, swap your color every turn, and put Bronstein behind a paywall. Flag does all of it, without a subscription. FIVE INCREMENT MODES • Fischer — increment added after every move. OTB and online standard. • Delay (USCF) — clock pauses for a fixed delay before counting down. • Bronstein — used time returned at end of move, capped at the increment. • Hourglass — time flows from one side to the other. • Byo-yomi — Japanese overtime periods after main time runs out. DISPLAY & TAP • Split or Color display modes. • Tap your own half (chess tradition) or tap anywhere — your choice. • Persistent White/Black sides — they don't swap based on turn.
