Chained: Timers run in sequence — when one finishes the next starts automatically. Drag the handle to reorder. Each timer alarms individually.
Chess / Alternating: Mobile — tap the top half to end Player 2's turn, tap the bottom half to end Player 1's turn. Desktop — tap the left side to end Player 1's turn (or press 1), tap the right side to end Player 2's turn (or press 0). Both sides count down simultaneously when paused; only the active player's clock runs.
