A quit, as the app runs it.
One tap logs a pouch.
From the phone, a widget, the Lock Screen or the watch, which asks before it logs. Three weeks of logging give the app your daily rate, your spending and how dependent you are. Everything it shows you afterwards is measured against that baseline, not against an average person.
Pick a day within 28 days, then stop.
In the one trial that tested both fairly, people who stopped outright were more likely to still be off nicotine at six months than people who tapered. Before the date is confirmed you write three if-then plans for the triggers you log most. You pay the $15 here.

Name the trigger, then wait five minutes.
Your plan for that trigger stays on the screen, on your wrist and in the Dynamic Island until you say how the craving ended. The app runs the clock so you do not have to watch one.

Twenty seconds every evening.
You rate eight withdrawal symptoms from None to Severe, starting on the first baseline day. The app draws them against the curve from 315 people who quit on their own, so you can see when yours should peak and when they should be gone.

One notification interrupts you. A lapse does not end the attempt.
The week-two alert is the only notification the app sends without being asked. A pouch after the quit date is logged as a lapse and the attempt continues. Seven straight days of pouches ends it, and the history keeps every attempt you have made.

Your heart rate, HRV, sleep, mood and weight.
The app reads them from Apple Health as seven-day averages and draws them against your baseline and the band the studies predict. In the one cohort of pouch quitters, resting heart rate fell 5.7 bpm in the first week. When yours runs outside the band, the card says so.

Where every number comes from.
The library holds 72 sources, each checked against its paper. Each claim in the app carries the population it was measured in and how many people that was. The only study of pouch quitters followed 37 people, and the app says so where it uses it. Tap a chip to read the study.

What it will not do.
Paid once, when you pick your date.
The baseline is free for up to 21 days. There is no subscription, and nothing you logged is ever locked. After 21 days without paying, logging and export stay free; the quit date and everything that runs from it are what the $15 buys. The app also keeps the other number: what you did not spend, worked out from your own can price and your own logs.
Questions.
No. The phone does everything. The watch adds logging and the craving timer on your wrist.
Start logging anyway. The baseline is free for 21 days, and after that the app asks you to pick a date.
The app only supports stopping outright. Pooled trials find tapering no better, and the best single trial found it worse. Lindson 2019 · 9,219 cigarette smokers in 22 studies
Log them. The app shades the charts while you use nicotine replacement and quotes the guideline, but it does not tell you how much to take.
No. It runs on iPhone and Apple Watch because the vitals come from Apple Health.
It stays on your phone. The app reads from Apple Health, never writes to it, and never syncs. Research mode is off unless you turn it on.
You keep logging and exporting, free. The quit date and everything that runs from it are the $15.
A few setup questions: how much you use and how soon after waking, one question about your heart, Apple Health access and four questions on mood. Heavy users then see what the guidelines say about medication.
It is built for nicotine pouches. The one cohort of pouch quitters included snus users, so snus is close. Vapes may come later; cigarettes are not planned. af Geijerstam 2025 · 37 snus and pouch quitters
