Smoking, drinking, vaping. Track everything you want to quit in one app. QuitDay shows the time you've been free, the money you've saved and how your body recovers, and helps you get through cravings. โ Several habits at once Track smoking, drinking and vaping, or make your own item such as late-night snacks or coffee. Each item can have its own currency and cost. โ A slip doesn't erase your progress Tap "I smoked again" and choose to start over or keep going after one slip. Your savings and best streak stay, and you can undo right away if you tapped by mistake. โ Hold on for 5 minutes Tap "I'm craving" to start a 5-minute timer with your reason to quit, the days you've held out and the cravings you've beaten. Beat it, and the moment is saved. โ Three home screen widgets See your days, savings and next recovery stage without opening the app. On iOS 17 or later, pick which item the small and medium widgets show. โ Stats and records See quit days, craving days and slips on a calendar, along with the hours cravings hit most and what sets them off. Add or fix records for past dates, and get cheer reminders at your toughest hours. โ Health recovery timeline See what changes in your body after you quit, step by step, with sources from the WHO, NHS and CDC. โ Reminders Daily cheers, milestones and recovery stage reminders keep you going. โ Switch phones without losing anything Export your records to a file and import them on your new phone. No account, no login. Everything stays on your device. โ Light and dark themes, large text, Korean and English Note: Health recovery information is general information based on public health sources and is not medical advice. Talk to a healthcare professional about your situation.

Verdict
The clearest difference is ads: WOLF at none against QuitDay's shown. WOLF also leads on update cadence (every 4 days vs every 4 months). QuitDay's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18). On price and in-app purchases there is nothing between them.
