Tempest

This companion app enhances the Tempest Game Clock (sold separately at tempestclock.com). This high-definition, full-color clock utilizes your Android phone as its display, complementing the deluxe, heavy-weighted Tempest Game Clock's traditional design. The clock uses a patented precision rocker controller (not the touchscreen) for gameplay. The app provides clear analog and digital timing options, accommodating increments, delays, sudden death, or overtime controls. Ideal for chess, backgammon, Go, Scrabble, Othello/Reversi, checkers/draughts, and other board games, the Tempest boasts a tournament mode that disables phone/text functions during rated games, adhering to FIDE and USCF regulations.
