A beautiful, true-to-life digital chess clock for two players, modelled on the professional DGT tournament clocks right down to the green LCD, the moulded plastic shell and the satisfying click of the rocker buttons. Set your time control, prop the phone between you, and play. FEATURES • One shared display, read the same way from both sides, just like a real chess clock • Four time-control modes: Sudden death, Fischer increment, Bronstein and US (simple) delay • Ready-made presets (5+0, 10+0, 3+2, 5+3, 15+10 and more) plus fully custom times • Tactile seesaw press buttons with a real switch click and haptic feedback • Choose from three press sounds • Low-time warning and automatic flag detection • Several clock finishes to suit your board • Designed for landscape play: turn the phone sideways and go PRIVATE BY DESIGN No account, no ads, no analytics, no tracking.

Verdict

The call

The clearest difference is in-app purchases: Digital Chess Clock at none against Alien Creeps TD's 10.

On price there is nothing between them.
