Nicotine Tracker - NicTracker

See your estimated blood nicotine level right now, and set spacing timers to help you use less.

NicTracker estimates how much nicotine is currently in your bloodstream based on the products you log throughout the day using a pharmacokinetic model. The app calculates absorption and clearance rates in real time, accounting for product type, body weight, and individual metabolism.

Apart from estimating the nicotine amount in your bloodstream, NicTracker also functions as a nicotine tracker app based on the products you log. Understanding exposure can also help people who are reducing or quitting nicotine.

Cigarettes, vapes, pouches, snus, gum, lozenges, patches, cigars, and hookah are each modelled separately, reflecting how differently nicotine enters the body depending on the delivery route. The home screen gauge updates continuously. The blood curve chart shows estimated concentration across the full day with a forward projection of expected clearance.

Logging takes under ten seconds. Doses can be entered retroactively and the model adjusts immediately.

The History tab tracks total intake and product use across daily, weekly, monthly, and yearly periods.

Widgets can be set up on Home Screen to view total daily use, 6-hour forecast chart and current nicotine amount in your bloodstream without having to open the app.

Insights (one-time purchase) provides trend analysis, recovery scoring, circadian usage profiling, and exposure intensity metrics generated entirely from your logged data.

All calculations run on-device. No data is transmitted externally.
