A streak is the cheapest possible progress display: one integer, incremented by showing up.
It has no target, no percentage, and nothing to complete, which is why it works on a
newcomer as well as on a veteran. Day one is a streak. What gives the number its weight is
the rule attached to it, that a single missed period returns it to zero, so the count is
not a record of what the reader did but a deposit they are holding. The specimen above
runs the same eighteen days three ways, and the only thing that separates a streak of
eighteen from a streak of nothing is one square.

The mechanic runs on loss aversion, and that is worth naming rather than dressing up.
Eighteen days of effort are equally real whether the counter says eighteen or zero, so what
the reset destroys is not progress, it is a number the interface invented and then made the
reader responsible for. Used honestly this is a fine motivator: the count is visible, the
rule is stated in advance, and the reader can decide how much they want to care. Used
commercially it becomes a lever, because the same mechanic that makes a streak worth
keeping makes a lost one worth paying to recover. A freeze given away, one or two a month,
absorbing the day someone was ill, is mercy that costs the product nothing. A freeze sold,
or a lost streak restorable for a fee, is charging for relief from a loss the design
manufactured, which is where the nudge stops being a nudge.

The comparison classes sort by what the reader is measured against. A
[leaderboard](/leaderboard) measures them against other people, so it says nothing useful
to anyone outside the top of it, while a streak measures them against their own past and
therefore has something to say on the first day. [Goal gradient](/goal-gradient) and
[endowed progress](/endowed-progress) are the two nearby motivators that need an endpoint
to work, a finish line to accelerate toward and a head start to make the line feel closer,
and a streak deliberately has neither. [Steps left](/steps-left) is the honest counter's
opposite number: it counts down to something that ends, where a streak counts up to
nothing and can only ever be lost.

Two details decide whether an implementation is humane. The first is what counts as a
period, because a streak on a calendar day punishes the reader in a timezone the product
did not think about and rewards a token gesture at 11:50pm; a rolling window, or a weekly
quota, measures the habit rather than the clock. The second is how loudly the loss is
announced. A counter that resets quietly and starts again is a habit tracker. A counter
that mourns, with a broken glyph and a push notification about the eighteen days the reader
just threw away, is
[nagging](/nagging) wearing a number.
