Start with a format both players understand
Short chess games need a clear agreement about time. Choose the starting minutes per player, decide whether to use increment or delay, and check the setup before either clock starts. A three-minute game with a two-second increment is different from three minutes with no extra time.
The app’s 3 and 5 minute presets are useful starting points for quick sessions. A 1 minute game makes the pace faster still. These are practical examples, not a claim that every preset is officially classified as Blitz under every organizer’s rules. Follow the format your club or opponent has agreed to play.
Set up the clock for a quick OTB game
- Put your iPhone or iPad beside the board so both players can reach their side.
- Select your starting-time preset.
- Choose Fischer, Bronstein or US Delay and the available value you want.
- Review the time-control summary together and press Start.
- Make your move on the physical board, then tap your active clock face.
Popular formats are faster to set up with the built-in options than by entering every value manually. Quick tournament presets are also included in the free app. Custom starting times and values outside the standard choices require the optional Pro unlock.
Should a Blitz game use increment?
Fischer increment adds the full selected number of seconds after each completed move. In a 3+2 game, each player starts with three minutes and receives two seconds after each successful clock press. A quick move can build remaining time, while a slower move spends more time than it earns.
For example, starting a turn with 30 seconds and taking one second leaves 29 seconds before the bonus. A two-second increment brings the clock to 31 seconds. If the move takes six seconds, the clock becomes 26 seconds after the same bonus. Increment does not mean that every turn has to be completed within two seconds.

Delay offers a different kind of breathing room
Bronstein and US Delay give each move a delay allowance without banking unused seconds. With a five-second delay, a move completed within three seconds does not reduce the settled main time. A move taking eight seconds costs three seconds of main time, assuming it is completed before expiration.
Bronstein counts down and refunds up to the delay on the clock press. US Delay holds the main clock while the delay runs first. Read the increment and delay comparison before choosing; equal numerical settings do not make Fischer and delay equivalent.
Keep turn switching and interruptions clear
In a fast game, a proper two-player clock keeps the time budgets separate and changes the active player with a tap. Make a few practice taps before your first game so both players understand the sides. Avoid tapping the opponent’s face or pressing twice after one move.
Chess Clock includes pause/resume, tenths below one minute, flag-fall detection, haptic feedback and an end-of-game signal. Pause for an agreed interruption instead of letting one player’s clock run while you discuss the issue. The app times the game; it does not monitor moves on the board.
Review the result, then choose the next format
Record White wins, Black wins or a draw after the game. The free history includes move count, time control and timestamps, useful when comparing several short games in a session. It does not provide move notation or chess analysis.
There are no ads between games and no subscription. Pro is a one-time upgrade for deeper timing customization, rather than a requirement for the basic modes. For the full device workflow, see using an iPhone as a chess clock. If you want a slower session, try the Rapid clock guide.
