Tikker, The Countdown Watch

The original idea behind Tikker was that you calculate how long you’re going to live, punch it in, and then watch the grains of sand slip through the hourglass of your life. That’s dark enough that I’d give it a pass, but according to its terrible customer reviews, it’s poorly made, hard to program, and considers a month to be exactly thirty days, rendering it useless for its pivot application of giving a countdown to an event or due-date of a project.
