StimuStop
StimuStop is a free streak tracker for smoking, vaping, nicotine pouches, alcohol, sugar, caffeine, gambling, social media and pornography. It runs in the browser and as an iPhone app, in English and Czech. The free tier has the counter, milestones sourced from the NHS, CDC, AHA and ACS, a journal, savings and community, with no ads. Premium in the iPhone app is a one-time purchase for unlimited habits, private messages and CSV export. A relapse resets the clock but keeps every milestone you reached.
Smoke Free
Smoke Free is one of the most used quit-smoking apps, with more than four million users according to its developer, over 40 health statistics, badges and paid "missions" that its developer says double the chance of reaching three months. Vaping is supported. It is available in English, French, German, Portuguese, Russian, Spanish and Welsh, not Czech. Pricing is a mix of one-time packs and subscriptions.
Kwit
Kwit combines a tracker with cognitive-behavioural exercises, breathing tools and a community, and it also tracks tapering off patches, gum and vapes. The app is ad-free. Most tools sit behind a subscription that is the most expensive in this comparison. Eleven languages, Czech is not one of them.
QuitNow
QuitNow is a long-running tracker with a large chat community, achievements and a health screen. It has the widest language support of the group, including Czech and Slovak. The free version shows ads, and its App Store privacy label says data is used to track you across other apps. PRO removes ads and unlocks the full health screen.
EasyQuit
EasyQuit offers a slow-reduction mode, a memory game for the first minutes of a craving, 57 badges and a savings goal with a photo. It is the cheapest paid upgrade here, a one-time $4.99. Ten languages without Czech, and the free tier carries ads with a tracking privacy label.
