PrasadSimpi/Smokey ? reverse-engineered prompt

Build me a Flutter app for quitting smoking that feels encouraging and simple to use.

I want it to show a big live clock for how long it’s been since my last cigarette, plus how many cigarettes I’ve avoided and how much money I’ve saved. The counting should be smart enough not to add cigarettes or savings while I’m asleep, but the quit timer itself should keep running all the time. It should also show a set of health milestones along the way, like when my heart rate starts to normalize and other progress points over time.

When a craving hits, I want a calm help screen with box breathing, quick distraction ideas, and my personal reasons for quitting. Let me set a savings goal for something I want to buy, and show a progress bar toward it. Also let me set reminder times for usual smoke breaks so the app can nudge me to breathe instead. If I slip, the clock should reset, but my totals should still stay intact.
