A DIFFERENT KIND OF CHESS CLOCK Tempest Deluxe is part app, part dock, pure genius. Crafted from a single slab of solid American Black Walnut finished with a large, premium genuine-leather touch surface. It’s ultra-heavy, rugged, and has a new zero-slip base—so it looks, feels, and sounds luxurious and plays solid, even in frantic time scrambles. You just download the inlcuded app and dock any phone to take advantage of your own large, clear display. The dock is a rocker with which the app interacts (sensing small amounts of tilt when you press it).

FEATURES NOT FOUND IN ANY OTHER CHESS CLOCK Customize colors per player. Toggle analog or digital clock faces. On-screen match scoreboard for Backgammon or Warhammer. Built-in Chess960 random position generator. Optional, crisp, voiced countdowns in 8 languages, Tournament Mode with intuitive, easy to set FIDE-style 3-period time controls. A growing list—powered by community ideas. Best of all, updates are always free, forever.

YOU'LL NEVER NEED A USER MANUAL AGAIN! Just swipe to set time controls in seconds — that's it. No manual needed. From casual chess with increments to FIDE multi-period matches, byo-yomi for Go, delays for Backgammon, and overtime for Scrabble. If you can say it, you can set it, within seconds, and without a manual. Try that with any other game clock!

JUST DOWNLOAD, DOCK & PLAY Free lifetime iOS & Android app. Huge, colorful display. Award-winning UX. Set any mode in seconds: Chess, Go, Backgammon, Scrabble, 1v1 games, with or without match scoring, even a multiplayer game pace-keeping mode for up to 20 players.

INVISIBLE TECH The innovative idea is that you already have the best screen and user interface device in your pocket (or collecting dust in the back of a junk drawer maybe?). So let's transform it into the best chess clock ever! How? The Tempest base holds any phone securely (even upside down!) while the Tempest app detects a small amount of tilt in the base when players hit it left or right. So our software uses tilt-detection designed into the base, it's purely mechanical and doesn't need batteries as a result. The tech is invisible leaving you to focus on the game. Clever isn't it?
