ZzzStake
A self-commitment app that turns your sleep data into a real-money stake against yourself — meet your sleep goal and keep your stake, miss it and forfeit it. Currently a live preview: stakes are tracked end to end, but no card is charged yet.
What it does
Pick a sleep goal — a sleep score, a consistent wake-up time, falling asleep by a set time, or hours slept — a window of nights, and a dollar amount. Meet it every night except the emergency skips you chose and you keep your money; miss it and the whole stake is forfeited.
Modeled on the loss-aversion commitment mechanic behind stickK and Beeminder, applied to sleep instead of weight or habits.
For score goals, ZzzStake computes its own score from your Apple Health sleep data — duration, consistency, and interruptions — and shows exactly how it's calculated. Not a black box.
A daily job settles every stake once its window closes and emails you the outcome. If you think a result is wrong, you can dispute it for human review.
