Four are ready or nearly ready. Each one exists because a specific group of people is currently doing this arithmetic by hand, in the Notes app, and getting it wrong.

Quitting nicotine pouches
Enter your brand, your strength and how many a day. NicotineTaperEngine returns a dated milligram step-down with hold days marked, and your resting heart rate is read from Health and charted against days clean — because the palpitations are usually the actual reason you are here, not the lungs.
Free forever: the counter, the log, the widget, the money figure. Paid: the taper schedule, the trigger analytics, the symptom timeline. $29.99 a year, or $4.99 a month, after a 7-day trial.

Skin picking, nail biting and hair pulling
Two taps to log an episode. Enough episodes and the app resolves the hour it happens to you — not a generic 10pm, your hour — and arms the replacement behaviour you chose in advance. The photo timeline uses a fixed frame, so the before and after are actually comparable.
Free forever: the episode log, the streak, one photo a week. Paid: the habit-reversal sequence, the full timeline, the trigger analytics. $34.99 a year, or $4.99 a month, after a 7-day trial.

Perimenopause symptoms and treatment
About twenty seconds a day: hot flushes, 3am waking, rage, joint pain, fog, bleeding. Log the day a dose changed and ChangeImpactEngine charts your severity against that date, waits out the lag before comparing anything, and reports what moved in plain numbers. If two things changed nine days apart it tells you the window cannot separate them, rather than picking one. Then it prints one page, ranked over ninety days, that a doctor will read in a ten-minute appointment.
Free forever: the daily card, the bleeding log, thirty days of history, the widget. Paid: unlimited history, the dose overlay, the pattern finder, the printable page. $44.99 a year, or $6.99 a month, after a 7-day trial.

Sports betting, the money rather than the block
Reconstruct what you are down, per book, all in. BurnRateEngine measures your own rate — with a fourteen-day coverage rule, a forty per cent outlier trim, and the rate clamped to zero rather than ever projecting a gain — and CounterfactualEngine runs the total of what you have not lost since your last bet. When the urge comes there is a ten-minute clock that cannot be skipped, and in that ten minutes the app does the arithmetic you never do: what you would have to hit to break even, what you actually hit on your last twenty bets like this one, and the expected result in dollars. Both buttons are always there at the end, including the honest one.
Free forever: the ledger, the streak, the money-not-lost figure, the ten-minute walkthrough. Paid: the accountability contact, the projections, the debt view, the relapse-audit history. $59.99 a year, or $9.99 a month, after a 7-day trial.
Stepdown, for vaping, is being reworked before it ships. Its legal pages are already live because an earlier build referenced them.
