The smallest possible thing that helps.

nil does three things, and tries to do them quietly: plan, log, look back.

Phase 1 · Wk 4 of 12
01 · Plan

A plan from now to zero.

Choose the Standard 12-week plan, the Gentle 16-week plan, or build your own custom taper. nil maps the dose for every day in between. Adjust anytime — the plan adjusts with you.

Today · 16 / 22 mg
4.0mg
＋ Log dose
02 · Log

One tap to log.

Log a dose from the home screen in a single tap. Widgets keep your daily progress visible at a glance — real life doesn't pause while you fumble with an app.

FAQ

Questions, before you start.

Is nil a medical device or treatment?＋
No. nil is a tracking tool — a quieter, more honest stand-in for the notebook on your kitchen counter. It is not a medical device and does not replace advice from a clinician. If you're starting NRT, talk to your doctor or pharmacist about a plan that fits you.
What does nil cost?＋
The full tracker — plan, log, history, widgets — is free. There's a small optional nil premium tier that supports development and unlocks extras like custom taper curves. No subscription is required to get to zero.
Can I export my data?Coming soon＋
Export is on the roadmap. You'll be able to download your full log as a CSV — every dose, every day — so your data is always yours to keep.
Will it work for vaping or smoking, not just NRT?＋
nil is built around milligram-of-nicotine, so it can model anything you can express in mg/day — including pod vapes and combustible cigarettes if you know your typical intake. The taper plans assume a steady reduction, which works for most products.
Does it work offline?＋
Yes. Logging, history, and your plan all work without a network connection. The only network calls are optional backup syncs and app-store update checks.
What if I miss a day, or go over plan?＋
Nothing happens. There's no streak to break. The week summary shows what actually happened, and tomorrow is a fresh row in the heatmap.
