The Headphones Are the Point
Money goals: how HabitApp turns kept commitments into things you can hold
There are two kinds of goals in HabitApp, and they need each other.
Life goals are the doing: the run, the study block, the daily post, the thing you're quitting. They carry the check-ins — the app asks whether you kept the commitment, on the cadence you set, and honest answers are what mint your minutes.
Money goals are the having: the headphones, the cruise, the jacket. Each one is a named thing with a price on it. Your check-ins fund them. Keep the commitment, and the goal at the top of your list accrues toward its price; when it's fully funded, you buy the thing, and the next goal in line starts filling.
Ten slots total, across both kinds. The cap is a feature — more on that below.
This is earmarking, and earmarking works
The money in a money goal is your own money. The app is a ledger, not a bank: it tracks what your kept commitments have earned toward the purchase you promised yourself, and funded means you've cleared yourself to buy it.
That sounds like an accounting trick, and it is — a well-documented one. People do not treat money as fungible, whatever economists say they should. Money assigned to a labeled purpose gets protected and pursued differently than money in the general pile (Thaler's mental accounting work, 1985–1999). A jar labeled "headphones" fills faster than a balance labeled nothing. The label does real work.
The other half of the mechanism is older: token economies — earn tokens for target behaviors, exchange them for chosen rewards — are among the most replicated tools in applied behavior analysis, in use since the 1960s. HabitApp's version just makes the token exchange rate explicit and lets you pick the backup reinforcer from the store of things you actually want.
Priority is a decision, not a list
When you have more than one money goal, their order matters: check-ins pay the top goal until it's funded, then the next. Reordering the list redirects the stream. This is deliberately a waterfall rather than a split — one goal funding visibly beats three goals crawling, because progress you can see is progress that reinforces (the same monitoring effect that makes the check-in itself work).
So the reorder handle is a real decision surface. Putting the cruise above the headphones is choosing which future arrives first, and the app treats the gesture with the same weight as reordering the goals themselves.
Why only ten slots
Because goals compete. Every goal you add dilutes the attention available to the others, and a list of twenty aspirations is functionally a list of zero. The slot cap forces the triage that makes the remaining goals real: to add the eleventh, something has to be retired or finished. Finishing one — answering the last check-in that funds the trip — is the best possible reason to open a slot.
The design bet, stated plainly: a kept commitment should end in something you can hold. The minutes are the daily currency; the headphones are the proof. When the goal funds, the purchase isn't an impulse buy, because you watched yourself earn it for six weeks. That is a different relationship with the thing than one-click checkout ever produced.
