Overnight re-plan
Every night the engine reads your real day — every puff, craving and slip — and rewrites tomorrow's allowance, safely clamped to your taper curve.
FinalPuff
Mobile health & habit appThe quit-vaping app that rebuilds tomorrow's plan around you, every night.
FinalPuff is a UK-first quit-vaping app built around one idea: the last one is the point. A lightning-fast puff tracker that works offline forever glides you down a personal taper curve — and while you sleep, an AI engine reads your actual day and rewrites tomorrow's plan, forecasts your craving windows with evidence from your own history, and writes every notification fresh. Your savings are counted at real UK prices, including the vape duty arriving 1 October 2026, and a slip never resets your progress.

FAQ
FinalPuff — questions & answers
What is FinalPuff?
FinalPuff is a quit-vaping app for the UK. It tracks puffs offline, glides you down a personal taper curve, and uses an AI engine that re-reads your entire history every night to rewrite tomorrow's plan, forecast craving windows and write genuinely personal notifications.
Does a slip reset my progress?
Never. A slip is logged as data, the app tells you honestly what caused it, and tomorrow's plan quietly absorbs it. Your day count, savings and plan all survive.
How much does FinalPuff cost?
There's a 21-day free trial, then £24.99 per year (or £4.99 monthly). Two days before the trial ends the app reminds you — with cancel instructions — and if you cancel, your log and history stay free forever.
How much will vaping cost after the 2026 UK vape duty?
From 1 October 2026 the UK's new Vaping Products Duty adds £2.20 per 10ml of e-liquid, whatever the nicotine strength — roughly £230 a year on top for a 20ml-a-week habit. FinalPuff counts your savings at these exact duty-inclusive prices, and the calculator on this page shows your personal figure.
When does the UK vaping tax start and how much is it?
The Vaping Products Duty takes effect on 1 October 2026 at £2.20 per 10ml of e-liquid. It makes vaping noticeably more expensive overnight — which is exactly when FinalPuff helps you quit, tracking every pound you don't spend to the penny as you taper down to zero.
