Good chess-clock etiquette is mostly agreement made before the first move. Decide the time control, who starts, which side each player taps, how an accidental tap is handled, and who may call a pause. Then use the same routine every move. 1Chess Clock provides the timer controls, but it does not replace the organiser's rules or decide a dispute for the players.
Agree the routine before play
Place the phone where both players can read the two panels and reach their own side. Read the starting time and the move rule together. Make one practice move from each side so everyone knows which panel to press. If you are using Fischer increment or Bronstein delay, confirm the mode before the game; the common time-control guide keeps the four common examples in one place.
Also agree what happens after a missed tap, a double tap, or a question about the display. In a casual game, the players can settle a simple correction immediately. In a club or formal event, follow the organiser or arbiter. Do not invent a new correction halfway through the game because one side is losing time.
General etiquette and formal rules
The general courtesy is simple: complete the move, press the clock, and move your hand away so the opponent can play. Do not hover over the control, press the opponent's side, or open settings while the game is running. For formal chess, the FIDE Laws of Chess, Article 6 describes clock operation and player responsibilities. Treat that source and the event regulations as the authority for a ruling; this guide is an app-use checklist, not a substitute for an arbiter.
The app's large player panels support a quick hand-over, but the physical courtesy remains the same. Wait until the display shows the other side as active before starting the next move. This prevents a phone from becoming a source of ambiguity at the board.
1Chess Clock operation
After making your move, tap your own side. Your time stops and the opponent's time starts. If the tap does not register or you touch twice, stop and apply the agreement made before play. Do not try to repair the situation by editing the time control while the game is live. For the basic flow, see how to get started with 1Chess Clock.
Use the central pause control when play must stop temporarily. Pausing is different from resetting: pause keeps the current session, while reset returns to the selected starting setup. The pause and reset guide explains the app distinction.
Pause and reset with consent
Say why you are pausing, use the central control, settle the interruption, and confirm whose clock should be active before resuming. Reset only when the game is over, abandoned, or both players clearly agree to start again. In a club, write the local procedure down so a coach, parent, or arbiter can apply it consistently; the clubs and coaches guide expands that setup.
