Quitting isn't one decision. It's one you make again every day, sometimes every hour. PureAir is there to make it easier: it keeps what you've gained in front of you, and when a craving comes, it helps you get through it. Quit in one day, or cut down step by step first. No account needed, and your health and smoking data stay on your phone. EVERYTHING YOU'VE GAINED, AT A GLANCE • Your smoke-free time counts up live, alongside money kept, cigarettes not smoked and estimated life regained. • When prices go up, enter the new one. Past days keep the price you paid then, so your savings never get inflated. • Choose your own currency, and set a savings goal if you like. WHAT'S CHANGING IN YOUR BODY • 23 milestones from 20 minutes to 20 years: your heart rate returns to normal, your blood carries more oxygen, breathing gets easier, your lungs start clearing themselves. • Recovery is gradual, not a switch. Each milestone explains what changes, why and for how long, and you can see which stage you're in. • Based on the CDC, the NHS and peer-reviewed research, with a source for every milestone. WHEN A CRAVING HITS • Most cravings pass within a few minutes. PureAir is built for those minutes: the "I want one" button sits at the top of the Today screen. • A guided breathing exercise starts the moment the screen opens: in for 4 seconds, hold for 4, out for 6. • If that isn't enough, there's more: delay, drink water, distract yourself, revisit your reasons, or watch the urge rise and fall like a wave without fighting it. • Once it passes, log how strong it was and what set it off. PREFER TO CUT DOWN FIRST? • Bring your daily number down step by step over one, two or three weeks, or a month. • Each day has an allowance that gets a little smaller. The day dial spreads it across your waking hours and shows when the next one is due. • Do better than your target and PureAir offers to lower your allowance, while your quit day stays where it is. • Ready sooner? Tap "I'm quitting completely now" on any day. • Log a cigarette with one tap from the home screen widget. SMOKED ONE? • One cigarette doesn't mean it's over. PureAir calls it a slip. • Your counter restarts, but the cigarettes you didn't smoke and the money you saved stay with you, and past attempts are kept in your archive. • No blame. Just two questions: what set it off, and what will you do next time? YOUR REASONS AND TRIGGERS • Pick why you're quitting and, if you like, put it in your own words. Each day PureAir brings back one of your reasons, tied to your own numbers, and your own words always come first. • Mark your triggers, like coffee, stress or after meals, and build a coping plan for each: what you'll do, and what you'll do if that doesn't work. MY JOURNAL • Your mood, the hours you struggle most, your longest smoke-free stretch and the cravings you've beaten, in one place. You can set a reminder for your toughest hours too. DEPENDENCE TEST AND LEARNING • The Fagerström test, also used in clinics, measures your nicotine dependence in six questions. • Ten topics in Learn: how long withdrawal lasts, patches and gum, prescription medication, weight, mood, alcohol, vaping, your home and children. HOME SCREEN AND LOCK SCREEN • Widgets show your smoke-free time or today's allowance, keep your own words in view and open your craving tools in one tap, on the Lock Screen too. NOTIFICATIONS • A note when you reach a milestone. If it would land between 10 pm and 8 am, it waits until morning. • A summary every Sunday evening. Craving support comes daily in the first weeks and less often over time. PRIVACY • No account, no sign-up. Your cravings, moods, plan and counter data are stored only on this phone, never sent to a server and never used for advertising. English and Turkish, light and dark themes. PureAir doesn't give personal medical advice. If you're thinking about nicotine patches, gum or prescription medication, talk to your doctor or pharmacist.

Verdict
The clearest difference is in-app purchases: PureAir at none against Interval Flow's 1. PureAir also leads on update cadence (every 5 days vs every 2 weeks). Interval Flow's advantage is ads (none vs shown) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
