Cold turkey fails most people. HalfPuff sets a gentle taper that halves toward zero at your pace — and makes logging a puff so easy the app never even opens.
Log a puff from the widget, Action Button, or Siri.
Ride out any craving with a guided breath.
Trends, rhythm, triggers — no paywall.
Your data is yours. No ads, no tracking.
Quitting shouldn't feel like a cliff. HalfPuff makes it a slope.
Cut one puff at a time. Nimbo's with you the whole way down.
Tap it and the count goes up — no launch, no fuss.
One press, screen off. The fastest puff logger there is.
“Log a puff in HalfPuff.” Hands-free, eyes-free.
Your count even survives an iOS update — the one number you can't afford to lose.
Tap once and Nimbo breathes with you — in, hold, out — while a soft ring counts down. Most cravings pass in less. No willpower lectures, no guilt. Just ninety seconds and a cloud who's got you.
A paced breath and a gentle voice — that's the whole rescue.
From the app, the lifebuoy tab, or even Siri — at your weakest moment.
The counter and every insight are free — forever. Pro is only the deeper, personal stuff.
Daily rhythm, your trend, and your top triggers — caught automatically, so the patterns show themselves. All free.
Widget, Control Center, Action Button, Back Tap, Siri — pick what fits you.
Set your own pace — faster or gentler. The whole curve recalculates to your life.
Connect Health and see your resting heart rate and sleep recover as your puffs drop. Proof you're getting better — from your own body, never uploaded anywhere.
A guided breath with Nimbo whenever the urge hits — free, and always a tap away.
No accounts, no ads, no tracking. Your puffs live on your phone, and the truth never costs extra.
Watch your daily target step down, week by week, until it reaches zero. Halve once, then halve again — and Nimbo's sky clears a little more each time.
