stickK vs Forfeit: Who Decides You Failed, and When

The Short Answer

stickK takes your word for it. Forfeit asks for proof.

That one difference decides almost everything else. On stickK you set a goal, put money behind it, and then report each period on whether you did the thing. Nobody checks unless you appointed a referee yourself. If you fail, the money goes to the recipient you named after the contract finishes, and stickK deducts its transaction and accounting costs before sending the rest.

On Forfeit you set a task, a deadline and an amount, then submit evidence before that deadline. A photo goes to an AI that compares it against what you said you would do. A timelapse goes to a human. GPS, Apple Health, RescueTime and Screen Time report on their own. Miss the deadline and Forfeit describes a pre-authorisation hold on your card that captures.

Pick stickK if the problem is that you have never made a goal cost anything. Pick Forfeit if the problem is that you talk yourself into counting a half-effort.

Every price and mechanic below was read from each company's own store listing, website or help centre on 19 August 2026, and anything we could not read first-party has been left out.

The difference that decides it: who says you failed

The two apps disagree about the thing that breaks accountability systems in practice, which is the moment you decide whether you did it.

stickK is an honour system with an optional witness. You file a report each reporting period saying you succeeded or you did not. Its help centre carries articles on how to submit a report, on what constitutes an unsuccessful report, and on what to do if you reported unsuccessfully by mistake and cannot change it. It also carries an article explaining what "On your Honor" means. That is a fair picture of how central self-reporting is to the design. You can add a Referee, and if you do, that person confirms or disputes what you filed. Without one, the honour system is the whole system.

Forfeit inverts this. Its App Store listing lays out the sequence: set the task and the deadline, submit your evidence, or you fail. The verification menu is long and each option has a different check behind it. A Photo Forfeit is reviewed by an AI that compares the image against your written description, and Forfeit's site says anything ambiguous goes to a human reviewer. A Timelapse is reviewed by a person. Self-Verify and Friend-Verify exist for things no camera can capture, like not drinking. Apple Health, GPS check-in, GPS avoid, RescueTime, Screen Time and a Pomodoro timer all report without you. If nothing lands before the deadline, the failure is automatic.

Forfeit then softens this on purpose, and the softening is part of the design rather than a loophole. The company says you can appeal a failed forfeit and that a human reviews the appeal within a few hours, and it explains the intent plainly: it wants failures to come from willpower rather than from life getting in the way. You choose a leniency mode of lenient, normal or hard, and hard mode refuses appeals altogether.

So the framing is about trust rather than severity. stickK asks you to be honest and gives you a way to invite a witness. Forfeit assumes you will not be honest and gives you a way to argue afterwards.

When your money actually moves

This is the part almost nobody writes down, and it changes how each app feels to use.

On stickK, nothing moves at the moment you miss. The company's help centre is direct about the timing: forfeited money is sent to the recipient you named once your Commitment Contract has ended, and that recipient then gets a payout request by email and accepts the money through PayPal. stickK's own FAQ adds the part worth reading twice. It says it will send the money you forfeit to your designated recipient at the end of the contract, minus the transaction fees and accounting costs it incurs. The amount that leaves you and the amount that arrives are different numbers.

On Forfeit, the charge is the event. The company describes a pre-authorisation hold on your card that captures when you fail, which is why its own marketing talks about the money being gone rather than owed. Forfeit keeps it by default, and the app lets you send it to a charity or to a group of friends instead.

That gap matters at 6am. A charge that lands today is a different signal from money that will leave you at the end of a contract, net of fees, through a PayPal request sent to your brother. Both are real consequences and they work on different timescales, which is why stickK suits a long horizon goal where signing the contract is itself the commitment, and Forfeit suits the daily miss you are trying to stop. We looked at the wider evidence on this in whether financial penalties change behavior.

What each one costs

Both are free to download, and each makes its money somewhere different.

Two notes on that table, because both are easy to get wrong.

stickK's $5 is newer than most write-ups about it, and it applies only to commitments with money attached. Its help centre calls it a flat $5 fee for new commitments that have money on them, applied once. Signing up costs nothing, and a commitment with no money on it is still free.

Forfeit genuinely does not publish a subscription price on its website. Its store listing reads free to download. If you want the current figure, read it in the store or inside the app rather than trusting any number quoted second-hand, including an older one of ours. We compared the wider field on price in Forfeit app alternatives.

"Forfeit is just a newer stickK" is wrong

Search this pairing and you will meet this claim quickly, in the auto-generated comparison page that currently ranks first and in the Reddit threads underneath it. It is the framing most likely to cost you if you act on it.

The two products do not share an enforcement model. stickK's own App Store listing describes it as a goal-setting platform, habit tracker and community created by behavioural economists from Yale University, and its design assumes the contract is the intervention: you write down what you will do, you attach money and a referee, and the writing down is what changes your behaviour. Forfeit was built for phones, and its design assumes the evidence is the intervention. One is a contract with an optional witness. The other is a verification pipeline with money attached.

The confusion runs in both directions. A review on stickK's own App Store page complains that Forfeit is the better functioning app but does not let you actually forfeit anything, which is the opposite error, since Forfeit charges cards routinely and publishes the totals. Its website states 686,000 forfeits set and $8.7 million staked, with a 94.2% success rate. Its store listing gives a slightly different cut of the same figures, more than 20,000 users and a 94% success rate over more than 75,000 forfeits, and says only 6% of forfeits fail.

Treat vendor statistics as vendor statistics. What they establish is that the mechanic runs at scale, which is the only claim worth taking from them.

What each one does not do

Worth knowing before you commit money to either.

stickK does not check anything. Unless you appoint a referee, your report is the record. If the reason your last three habit attempts collapsed is that you talked yourself into counting a half-effort, stickK will let you keep doing that for the length of the contract and then not charge you. Verification is the weakest part of the product and always has been.

stickK's anti-charity list is a blunt instrument. The mechanism is real and it works on some people. You name an organisation whose views you strongly oppose, and the prospect of funding it is the pressure. The published list is built from pairs on opposite sides of contested issues, so that whichever side you sit on, there is something on it you would hate to fund. It also includes several football clubs, which tells you how the lever is meant to feel. The catch is that the pressure only exists if you hold strong views and are genuinely willing to route real money to something you object to.

Forfeit's review path has limits. Photo review is automated in the first instance, and Self-Verify and Friend-Verify skip outside review entirely by design. An app that lets you self-verify has the same hole stickK has, in the cases where you pick that option.

Forfeit's consequence is configurable enough to be soft. Because the accountability method can be an email to a friend rather than a charge, you can set up a forfeit that costs you nothing. That flexibility is a genuine feature for people who will not attach a card. It is also the first place to look if the app stops working on you.

Neither one calls you. Both wait for you to come to them. If the failure you are trying to fix is forgetting rather than fudging, that matters more than anything above.

Where FineStreak fits

We build a third thing, so read this section knowing that.

FineStreak is the case where the check-in comes to you. You set a goal, a check-in time and a fine, and an Agent calls or texts at that time rather than waiting for you to open an app. Verification is genuinely checked rather than self-reported: a vision model matched against your specific goal, perceptual-hash blocking of photos you have sent before, EXIF capture time, error-level analysis, and flagging of instructions hidden inside images. The fine runs from $0.10 up to your rank cap, which is $3 at Committed, the rank where fines unlock, and $50 at Legendary, and you set the number.

Where that leaves the comparison honestly: stickK is the cheapest way to find out whether a written contract is enough for you, Forfeit is the strongest evidence layer of the three if you will do the submitting, and FineStreak is the one that starts the conversation at the time you said. We are pre-launch, with no checkout live yet. You can start a free week, which is seven days with no card.

If verification is the specific thing you care about, we went deeper on it in habit trackers with photo proof.

Which should you pick

Pick stickK if you want a long contract, you are honest in your own reporting or you have a real person willing to referee, and you like the idea of your money going somewhere specific if you fail. At $5 a contract it is a cheap way to test whether a written commitment moves you.

Pick Forfeit if you already know self-reporting does not work on you. The evidence requirement is the product, and the appeals path means a genuinely bad week does not have to cost you.

Pick neither if the real problem is that you forget. Both apps sit still and wait. A goal you never open the app for fails on both, quietly on stickK and expensively on Forfeit.

If you are still deciding what kind of commitment device suits you at all, what is a commitment contract covers the mechanics, and commitment devices that work ranks the wider field by evidence.
