Four Commitment Devices That Predate the App Store

Commitment devices predate commitment apps by well over a century. Christmas club savings accounts, wedding weight-loss bets among friends, and Peloton’s public leaderboard are all real examples that forced people to follow through using money, social exposure, or locked access — no software involved.

That’s worth sitting with before the list. The oldest version of tying yourself to the mast predates smartphones by about three thousand years, and even the people who figured out how to wake an entire town before alarm clocks existed were running a version of the same trick: a real person checking, in person, whether you’d actually followed through.

1. Christmas Club Savings Accounts

Starting around 1909, small American banks — the Carlisle Trust Company in Pennsylvania is usually credited as an early one — offered a savings account with one flaw built in on purpose: you couldn’t withdraw from it until a fixed date each fall, right before the holiday shopping season. Depositors put in a set amount weekly, often a dollar or less, and earned little or no interest. That was the trade people wanted. A regular savings account left the money reachable, and reachable money got spent. Locking it away solved a problem people already knew they had with themselves. The modern descendant of that same instinct is cash-envelope budgeting and the no-spend-month challenge, where portioning out physical bills in advance does the same locking-away job a passbook once did. By the 1920s the product was common enough that banks printed passbooks specifically for it, with a page for a teller to stamp each week.

2. StickK’s Anti-Charity Pledge

StickK, the commitment-contract site co-founded by Yale economist Dean Karlan, lets users put money on a goal and name an “anti-charity” — an organization they actively dislike — to receive it if they fail. The money going to a cause you find distasteful, rather than one you’re neutral about, is the whole point: it removes any comfort in failing. A separate post on this blog goes deep on how StickK and Beeminder price that penalty, so I’ll leave the mechanics there.

3. Wedding Weight-Loss Bets Among Friends

This one has no company behind it at all. A group of friends with a wedding on the calendar agrees on a target, sets a final weigh-in date, pools money up front, and the person furthest off target — or everyone who missed it — pays the rest. What makes it hold isn’t the cash so much as the scale: a public number on a specific morning, read out in front of people who already know what you promised months earlier.

4. Peloton’s Public Leaderboard

Peloton never asked users to sign a pledge. It just showed everyone’s live pace on screen during every class, ranked, with usernames attached. Riders who logged in planning a quiet workout have described picking up the pace specifically to not finish last in front of strangers — an outcome nobody asked for and plenty of people can’t turn off. That’s the interesting part: the leaderboard isn’t a contract anyone agreed to. It’s exposure that happens to function like one.

Four different eras, four different penalties — a bank that won’t release your own money, a check to an organization you can’t stand, a friend holding cash at a weigh-in, a scoreboard you didn’t ask to be ranked on. Which one would actually get you out of bed: losing money, losing face with a friend, or just being watched? A fifth version runs on none of the above: F3 Nation gets thousands of people to a free 5:30 a.m. workout with no money and no leaderboard at all, just a public text the night before and a small group who’ll notice if it wasn’t kept.

None of these four require an app, which is worth sitting with if you’re evaluating a modern wake-up tool: six low-tech commitment devices built specifically around getting out of bed run on the same underlying levers — money, a witness, or a locked door — as the Christmas club account did in 1909. And the engineering term for what all four examples share, a constraint that makes the wrong move harder rather than just unwise, gets its own definition here.
