StickK vs Beeminder: Which Commitment App to Pick (2026)

The Short Answer

StickK and Beeminder both take money from you per reporting period, so the choice is not about which one is stricter. It comes down to who decides you failed and what happens to the money. StickK puts a human in that seat: you file a report, or a referee you nominated files it, and the card you registered is charged within 48 hours of a bad period, always for the amount you named. The money goes to a person or organization you chose in advance. Beeminder puts the data in that seat: you commit to a rate, feed the graph, and you derail the moment your numbers fall under the line, paying an amount that climbs $0, $5, $10, $30, $90, $270 as you keep missing. Beeminder keeps that money. StickK costs $5 to open a funded contract in 2026 and Beeminder's core tier is free.

The difference that actually decides it

Pick based on which of these two sentences describes you.

"I will do the work if someone is watching." That is StickK. Its whole design assumes a person in the loop, and the referee is the product.

"I will do the work if the numbers are undeniable." That is Beeminder. Its whole design assumes a graph in the loop, and the data is the product.

Almost every other difference between them follows from that one choice. It is the same split we drew across the wider field in commitment devices that work: some devices borrow a human's judgment, and some replace it with a measurement.

How each one takes the money

Every figure below was read from each company's own site and help center on 14 August 2026.

Three details are worth more than the rest of the table.

StickK is no longer free to start. Its help center states that a flat $5 applies to new commitments with money attached, charged once at creation, refundable if you cancel and contact support. Contracts with no money attached stay free. There is also a $1 authorization hold placed on your card to confirm it works, released after 30 days, which is a check rather than a charge. StickK remains the cheaper entry point of the two, and the "completely free" line you will read almost everywhere else is now out of date.

Beeminder's pledge is designed to escalate. The ladder starts at $0, so your first derailment on a new goal is a warning shot. After that it climbs to $5, $10, $30, $90 and $270 unless you cap it, and capping is available on the free tier. Beeminder is unusually direct about the incentive this creates, stating on its own pricing page that users fund the company mainly through derailment payments, and that "if you never derail, you're not actually pushing yourself." Its stated philosophy is that "derailing it is nailing it." Read that as candor or as an awkward alignment of interests, but read it before you commit.

Only StickK lets the money hurt socially. You nominate who receives it: a friend, a foe, a charity, or an anti-charity, which is StickK's term for an organization whose views you oppose. You cannot send it to a charity you like, and StickK explains why in plain terms, arguing there is less incentive to succeed if the money ends up somewhere you are happy about. Beeminder simply keeps the pledge, apart from the half-to-charity option on the $81 tier, and refuses anti-charities outright on ethical grounds. We compare every app's money destination in anti-charity apps.

What each one can actually verify

Neither product examines evidence. This is the most useful thing to know before paying either of them.

Beeminder accepts numbers. You type them in, or you connect one of its autodata integrations and let another service send them. That is genuinely strong for anything a device already counts, such as steps, hours logged, words written or weight recorded. It has nothing to offer on anything a device cannot see, because a number you type is a claim about yourself.

StickK accepts reports. On your honor, you file the outcome yourself. With a referee, a person you nominated confirms or denies it, which moves the judgment to someone who knows you and can be disappointed in you. StickK's own material claims a referee raises success odds by up to 2x and money by up to 3x. Those are the company's own figures, published on its tour page, so weigh them as a vendor's claim.

There is a real strength hiding in StickK's design here. Because a missed report counts as failure automatically, the app closes the escape hatch that kills most habit tracking, which is quietly stopping and telling yourself you will restart Monday. Daily commitments get a 24-hour window, weekly and one-shot commitments get 72 hours, and after that the period is marked No Report Submitted and charged like any other miss.

What both share is that a determined person can misreport. That gap is why verified photo proof exists as a separate category.

Which should you pick

Choose Beeminder if the way you fail is gradual. You start strong, drift across two weeks, and notice once the habit is gone. Beeminder prices drift on the day it starts, and the rising pledge means the second slip costs more than the first. It suits anyone whose goal is already counted by a device, because the integrations then handle reporting. It rewards people who like graphs and can live with a system that never lets go. If the goal is a discrete task rather than a rate, the closer contest is Forfeit vs Beeminder. And if Beeminder is not really in your running and it is the two commitment-contract apps you are weighing, we settle that pairing in stickK vs Forfeit.

Choose StickK if you want a person involved and a named consequence. A referee who will actually file an honest report is the strongest mechanism either of these products offers, and sending your money somewhere you would hate is a lever unique to StickK. It also suits one bounded promise better, which Beeminder concedes in its own comparison article, pointing readers elsewhere if they want more help with short-term goals or are "less of a data nerd."

Choose neither if the thing that stops you is that nothing reaches you at the moment you are about to skip. Both products wait for you to come to them. Beeminder's graph sits there and StickK's reporting window sits there, and in both cases you are the one who has to show up. Pricing a miss and preventing one are different jobs.

Where FineStreak fits

We build a competing product, so read this section knowing that.

FineStreak sits closer to StickK on who is involved and closer to Beeminder on frequency. You set a goal, a check-in time and, if you want one, a fine. An Agent then calls or texts you at the time you chose and asks for proof. What differs from both apps above is what happens next, because the proof is examined. A vision model matched to that specific goal reads the photo, screenshot or location, perceptual hashing blocks a re-sent image, capture time is read from the file, error-level analysis looks for editing, and anything trying to talk its way past the check gets flagged. A number you typed will not clear that, and neither will last week's photo.

The fine is optional and slides from $0.10 up to your rank cap, which runs from $3 at Committed, the rank where fines unlock, to $50 at Legendary. There is no checkout live yet, because the full iOS app is the launch and it arrives in mid-August 2026. What you can do today is run a free week with no card.

For the wider field rather than this head to head, we keep a ranked list of StickK alternatives, a separate one for Beeminder alternatives, and a plain explainer on what a commitment contract actually is.
