Logging puffs
Add the HalfPuff "Log a Puff" widget to your Home or Lock Screen and tap it — the count goes up and the app never opens. You can also assign it to the Action Button, Back Tap, the Control Center control, or say "Log a puff in HalfPuff" to Siri. Open Settings → "Make it effortless" in the app to set these up.
Yes. On the Today screen, touch and hold the + button to open "Lost count?" and add the puffs you didn't catch in the moment. An honest number matters more than a perfect one.
No. Your logs are stored in a way that survives app and iOS updates — that's the one number you can't afford to lose.
Yes — right after you log, tap a trigger chip (Stress, Boredom, After meal, and so on). Those build your Top Triggers in Insights.
The taper plan
HalfPuff sets a daily target that halves toward zero over time, so you reduce gradually instead of quitting cold turkey. Your Plan screen shows the whole curve and your projected vape-free date.
Yes, with HalfPuff Pro. The Custom Taper Plan lets you pick your own pace — gentler or quicker — and the whole curve recalculates around your life.
Nothing bad happens. HalfPuff never punishes you — tomorrow's a fresh start, and Nimbo stays right where they are.
Craving rescue
When a craving hits, open the SOS (the lifebuoy) and Nimbo breathes with you for ninety seconds — in, hold, out — while a soft ring counts down. Most cravings pass in less. You can also reach it hands-free with Siri.
No. You can close it anytime, or tap "Log a puff instead" — no guilt either way.
Insights & Recovery
Yes. Your daily rhythm, trend, and top triggers are all free — knowing yourself shouldn't be behind a paywall.
With HalfPuff Pro, Recovery connects to Apple Health (read-only) to show how your resting heart rate and sleep are recovering as your puffs drop. Your health data is processed on your device and is never uploaded.
Recovery needs a little Health history to show a trend. Give it some time wearing your Apple Watch or tracking sleep, and check that you granted Health access in iOS Settings → Health → Data Access.
Subscription & privacy
Free, forever: one-tap logging, the craving rescue, and every insight. Pro adds the Custom Taper Plan (your own pace) and Recovery (watch your body heal).
Tap "Restore Purchases" in Settings to restore. To cancel, go to iOS Settings → your name → Subscriptions → HalfPuff. Billing is handled entirely by Apple.
On your device. HalfPuff has no accounts, no ads, and no tracking. See our Privacy Policy for the full picture.
