I built a private, local-first app to taper off nicotine, with no backend and a public repo.
I quit nicotine pouches the hard way a few times. Cold turkey, relapse, repeat. What I actually wanted was something gentler, a plan that steps me down gradually instead of demanding I stop overnight. Every app I tried either pushed cold turkey or wanted an account and shipped my health data off to some cloud. For a health app, that felt backwards.
So I built Wean Nicotine. It does one thing. You set your baseline and a weekly reduction pace, and it gives you a calm daily allowance that tapers over time. You log a pouch in one tap, handle cravings with a few built-in tools, and watch your progress.
The part I care most about is that it's fully local-first. No account, no cloud sync, no backend at all. Everything lives in on-device SQLite, so your usage data never leaves your phone. I wrote up why I went this route in .
For the makers here, a few details. The stack is Expo and React Native with local SQLite, iOS first. Because it's local-first there's no server to run, which means nothing to operate or pay for, and nothing to breach. The whole thing is open source under MIT, including the Astro marketing site, at github.com/JarlLyng/wean-nicotine.
I just shipped v1.4.1 to the App Store. Shipping isn't glamorous. Version 1.4.0 had a regression that made every button unresponsive, because an animated Pressable quietly dropped its press handler, so 1.4.1 is the hotfix. It's live and working now.
If you're trying to cut down rather than quit outright, I also put together .
It's a one-time purchase on the App Store, with no subscription if you want to look: .
One question for the room. For a product where privacy is the actual pitch, how would you market it without sounding preachy? I'm genuinely unsure how to lead with "we don't take your data" without it reading as a gimmick.
