What's New in Nicotine Tracker
1.2.1
July 19, 2026
What's new: - A streak counter now sits at the top of the Home screen and counts the days in a row you have logged. Clean days count as well, so you can mark a day with no use and keep your streak going. A reminder arrives half an hour before a streak is due to end. - The blood curve can now be viewed over 3, 6, 12, or 24 hours. Each view stays centered on the current moment, showing you the hours behind and the hours ahead, and it shifts along as time passes. You can drag backwards through the past week to revisit earlier curves, and a button brings you back to now. - Insights has two new cards. One explains why your use changed from last week to this one, showing whether you are using more often or taking more per use. The other shows the blood nicotine level you carry into each day before your first use. - Managing your saved products is now simpler. Editing and deleting are handled in the Log tab through a new selection mode, and the older long-press menu has been removed. - Saved products are no longer shown in Settings, since everything you need to manage them now lives in the Log tab. - Several bugs were fixed and the app runs more smoothly.
