Tempest

This is a companion app for the Tempest Clock (sold separately). This app works with the Tempest Game Clock (available at tempestclock.com), a unique, tournament-style, heavy-weighted game clock that uses your Android phone as its high-definition, full-color display. This app is designed exclusively for owners of the Tempest Game Clock: a deluxe, heavy-weighted, traditional chess clock featuring a patented precision rocker controller (used during gameplay, not the touchscreen). It pairs with this app to provide clear analog and digital game timing with customizable options including increments, delays, sudden death, and overtime controls. Ideal for Chess, Backgammon, Go, Scrabble, Othello/Reversi, Checkers/Draughts, and other board games. Tempest includes a strict TOURNAMENT MODE which disables all phone/text functionality during rated games, complying with FIDE and USCF guidelines. To see the clock in action and to order yours, please visit tempestclock.com.
