Best accountability apps, by what's at stake

What separates these apps is what they take from you when you fail. That makes the choice a question about you rather than about them, because a stake you can shrug off is not a stake.

Four kinds, what each actually risks, and who each one suits.

Prices and mechanics were checked on 19 August 2026, in each product’s own app or signup flow rather than from its marketing pages. All of them can change without notice.

The four kinds of stake

Money at stake

The oldest idea in the category and the best evidenced. You attach cash to a promise, and breaking the promise costs you.

Note that this category has thinned. Forfeit was the best-known money-stake app and, in the UK at least, no longer takes money at all. Of the two left, Beeminder is all-in on money and stickK lets you choose. See below.

Beeminder

A graph with a “bright red line” you must stay on the right side of. Cross it and you pay, on an escalating schedule: $0, $5, $10, $30, $90, $270, rising each time you derail. Money is the only stake, and it is the purest version of the idea on this page.

When this was written there was no signing up inside the app; you register on the web. “The very act of signing up for Beeminder is itself a commitment device”, because if you do not start a goal within a week, they charge you $5. You have to type out in your own words that you intend to create a goal and accept the charge if you do not, then you store a card with Stripe, and their page is explicit that registration is not complete until you do.

So the honest way to describe the price is: a card up front, $5 at risk before you have set a single goal, then $8, $16 or $81 a month for Infinibee, Bee Plus or Beemium, roughly 14% off annually, plus whatever you derail.

Beeminder auto-imports from around forty sources, Apple Health, Strava and Fitbit among them, so for most goals the tracking happens without you. They have been running since 2011, which in this category is a long time.

Suits you if you want quantified data, a stake that escalates until it hurts, and you read that signup screen and felt more interested rather than less. That reaction is a good self-test, and they clearly designed it as one. Does not if you want to start in five minutes on your phone, or if handing over a card before you have a goal is a step too far.

stickK

Free to use, built by behavioural economists at Yale, and the most configurable version of the idea. You set a goal, choose whether to put money on it, and name a referee.

Checked 19 August 2026. The stake has four possible destinations: a charity, an anti-charity you actively oppose, stickK itself, or no money at all. The anti-charity is the sharpest tool in the category, because paying a cause you hate hurts more than simply losing the sum, and this is the only place here you can do it.

Two details matter more than the pricing. First, the referee can be an invited friend or you, and naming yourself means the whole contract runs on your own word. Second, goal creation happens on stickK’s website rather than in the app, so expect to set things up in a browser and use the app to check in.

Suits you if you want to choose your own stake, and especially if the anti-charity makes you wince. It is also the gentler entry point of the two money apps, since nothing forces you to put cash on the line at all. Does not if you want verification that happens without you: stickK rests on reporting and referees, not on reading your Apple Health.

Your apps at stake

Dare

The stake is not money. You commit to a goal, a daily step count, exercise minutes, active calories or a bedtime, with a deadline. Dare reads Apple Health to check it. Nothing is blocked while you are hitting the goal. Miss the deadline and the apps you nominated lock until you make it up.

There is no button to mark a day complete, which is the design: the verification happens without you, so there is nothing to negotiate with at 9pm.

It is $49.99 a year, $7.99 a month, or $79.99 once in the US, with deliberately lower prices in 35 territories. Built for iPhone.

If what you want is a blocker that runs on a schedule rather than a consequence for missing, that is a different kind of tool, and Dare compared with Opal covers it. The free version of that tool is already on your phone: Dare against Apple’s own Screen Time is the comparison to read before paying for any of this.

Suits you if the thing you actually do instead of training is scroll, so taking that away is both the punishment and the cure. Does not if you have no fitness goal to attach it to, or if the way you train does not show up in Apple Health.

Letting someone find out

Forfeit

Forfeit is the app most people mean when they say “the one that charges you”, and that is no longer what it does, at least not here.

Checked inside the UK app on 19 August 2026: there is no money stake. You state what you will do and by when, and if you miss it, Forfeit sends a text or an email to a friend you nominated. The stake is embarrassment, not cash.

Their own website still describes the old model in detail, including Stripe pre-authorising a sum you set and a running total of dollars staked. We could not establish whether the money version is still live in other countries, so if you are outside the UK, check inside the app before assuming either way.

Pricing is monthly only: £7.99 for Premium, £12.99 for Pro, with no annual plan and no free trial. The free tier allows one goal. Pro adds unlimited goals, an AI that phones you, and an “Overlord chat” assistant.

Suits you if a friend being told is the thing you would actually dread, and you want a wide range of goal types with automatic checking. Does not if you specifically wanted money on the line, which is the reason many people go looking for it.

Habitica

Your tasks become an RPG. Completing them earns experience, gold and equipment; skipping them costs you progress. “Parties let you team up with friends for extra accountability”, which is where the actual pressure comes from, since the game alone is a game.

Free, with subscriptions from £4.99 a month to £45.99 a year and cosmetic gem packs from £0.99. iPhone, iPad and Vision. 4.0 stars from 335 ratings at the time of writing.

Suits you if you find shared progress motivating and money coercive. Does not if you have ever quietly abandoned a game.

A person at stake

Worth saying plainly, because no app on this list beats it: a real person expecting you at a specific time is the strongest accountability mechanism there is. A trainer, a running club, a friend who will actually text.

Apps exist because people are expensive and unreliable, not because they work better. If you can arrange a person, arrange a person.

Which should you pick?

One question decides it: what would you actually feel losing? If a charge on your card would get you out of bed, that is Beeminder for escalation and graphs, or stickK for the anti-charity and a softer start. Notably it is no longer Forfeit, in the UK. If money is not the lever, then the stake has to be something you cannot buy your way out of, like the apps on your phone. That is what Dare takes.

If the thing you would dread is someone knowing you did not honour it, Forfeit tells a friend and Habitica shows a party. Or better, a person.

Does any of this work?

The mechanism is sound. Commitment devices, where you deliberately remove your own future options, are well studied and effective, and a deadline with a specific time attached beats a vague intention.

Whether any specific app works is a separate question. Several publish success rates, but all of them, including ours, are self-reported.

Checked on 19 August 2026, all of it first-hand: Forfeit from inside the UK app, with its platform and verification details from forfeit.app; Beeminder from its signup flow, with tier prices from beeminder.com/premium; stickK from its signup flow, with the Yale attribution from stickk.com; Habitica from its GB App Store listing. Dare’s prices come from our own App Store Connect data on the same date.

No efficacy comparison is made between any of these products, because none has an independent trial and comparing self-reported figures would mislead. Where a product’s own site does not state something, this post does not either.
