What makes it different

FAQ

Questions, answered.

How do I quit Zyn / nicotine pouches?

Day One doesn't treat dependence. It helps you track: log each pouch, start a 5-minute craving timer when an urge hits, use the breathing guide or a game, and build a nicotine-free streak. It is not medical advice; talk to a healthcare professional about quitting.

How long do nicotine cravings last?

Day One's timer is 5 minutes, built for riding out one urge.

What happens to your body when you quit nicotine, day by day?

The in-app timeline is sourced from the American Cancer Society, CDC and NHS and shows what's coming each day. A subscription unlocks future days.

How much money do I save quitting Zyn?

Is Day One free?

The pouch counter, the 5-minute craving timer and the games are free. An optional subscription unlocks the full 365-day recovery guide, future timeline days and streak insurance. Prices are shown in the App Store.

Do I need an account? What data does it collect?

No account. Per the App Store listing: a pseudonymous identifier, product-interaction and subscription data and crash diagnostics. The pouch log stays on your device and, if enabled, in your iCloud.
