Tempest Game Clock

Tempest Game Clock is a premium chess clock that docks your smartphone in a purpose-built walnut and leather housing, turning your phone into a full-featured game timer. The free app (iOS and Android) handles all timing logic, while the physical dock gives it the feel and structure of a traditional chess clock. Tempest offers two dock styles: the all-black Classic and the Deluxe with walnut and leather finish.

The app supports all standard time controls including increment, delay, and Fischer formats, and includes a dedicated Tournament Mode that disables phone and text functionality during play to minimize distractions. Beyond chess, Tempest works for Go, backgammon, and other timed board games. The hardware retails at around $39, making it more accessible than most dedicated chess clocks.

It is worth noting that because the Tempest uses a smartphone rather than a standalone device, it is not currently approved for FIDE or USCF-rated play. The developers have been in dialogue with governing bodies on the matter. For casual club play, home use, and unrated games, it is a stylish and practical option that keeps your timing setup simple and modern.
