Lueur

Almost every app that helps you smoke less shows how much money you’ve saved. That works for some people, but not for everyone.

I wanted something else: treating cutting down as training, a bit like getting better at a sport.

You give your usual maximum and a pace: gentle, balanced or bold (these choices⁰²). Every day the app draws a number in the range that follows, and that’s the day’s quota. You can also pick total chance, from 1 up to your maximum.

Since you don’t know the number in advance, you stop smoking on autopilot. Each cigarette becomes a choice.

• the day’s quota⁰⁴, with a ring that fills up;
• a counter you tap once per cigarette, with undo;
• your history over the last seven days;
• a reminder⁰³ every morning with the quota, only if you want it;
• a light and a dark⁰⁵ theme, and text that scales up without breaking anything.

Everything stays on the phone: no account, no server, nothing is sent anywhere. Quotas are drawn ahead and saved, so closing and reopening the app changes nothing.

One setting is left to each person (in the settings⁰⁶): whether the day’s quota stays frozen, or is drawn again when you change your maximum. It’s frozen by default, otherwise you could keep rerolling until you get the number you like.

No lecturing either. When you go over, the app says it’s fine and tomorrow starts from zero. For real support, it points to the French helpline Tabac info service, 39 89 (help page⁰⁷).

I made a first version this summer. In November I rebuilt it from scratch with what I’ve learned since: the code is split into layers, 27 tests run on every change, and I checked contrast, enlarged text and reduced motion. I still have to try it on real phones and set up the accounts to publish it. The code is public.
