Track blood nicotine levels in real time, whether you're a heavy user, cutting back, or working toward cessation. NicTracker estimates how much nicotine is in your bloodstream using a pharmacokinetic model. The app calculates absorption and clearance based on the product you log, your body weight, and your personal metabolism settings, then updates a live gauge as the level rises and falls throughout the day. The following product types are each modeled with their own release and absorption curve: Cigarettes and cigars Vapes and hookah Nicotine pouches (Zyn, Velo, and other brands) Snus, gum, lozenges, and patches Reducing your intake or moving toward smoking or tobacco cessation starts with seeing the pattern behind it. The Insights tab (one-time purchase) analyzes your logged data for usage trends, recovery scoring between doses, and a circadian breakdown of when cravings tend to hit. The Home screen spacing timer helps you space out use and build toward a new habit, one interval at a time. Other things NicTracker does: Logs a dose in under ten seconds, with retroactive entry if you forget to log in the moment Shows a full-day blood curve chart with a forward projection of expected clearance Tracks total intake and product use across daily, weekly, monthly, and yearly views in the History tab Adds Home Screen widgets for daily use, a 6-hour forecast, and your current blood nicotine level Exports your logged data and blood curve as a PDF or CSV for any date range All calculations run on-device.
