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. ALSO IN FLAG • Full game history with per-move timing • Stats dashboard — averages, move-time charts, time-trouble heatmap • Pause, resign, agree-draw shortcuts • Customizable haptics and sounds • Custom time-control presets — bullet, blitz, rapid, classical, byo-yomi PRO — ONE-TIME UNLOCK. NO SUBSCRIPTION. 7-day trial of every Pro feature. After that, a one-time unlock keeps everything forever. No subscription. No ads. Pay once, own it.

Verdict
The clearest difference is in-app purchases: ChessLink App at none against Flag's 1. ChessLink App also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). Flag's advantage is update cadence (every 2 days vs every 3 months). On price and ads there is nothing between them.
