Quit smoking app for iPhone and Android
Quitzilla counts every smoke-free minute and the money you don't spend on cigarettes, and keeps your reasons to quit one tap away.

Set the day you quit and what smoking cost you. Quitzilla keeps this count in the app, and it grows with every smoke-free day.

In Quitzilla, a reward fills up from your savings until you can buy it. Some examples:
How it helps
No judgment and no lectures. Just your own reasons, an honest record and a clear view of how far you've come.
Reasons to Quit
An example list. Yours can say anything.
When you set up Smoking, Quitzilla suggests reasons to quit. Keep them, rewrite them or add your own, and open the list whenever you want a cigarette.
Diary noteCoffee break with coworkers and I caved. Next time, I'll walk around the block instead.
If you smoke, log it in the diary as a relapse. The timer restarts, your history and records stay, and a quick note helps you see what led to it.
Charts show every smoke-free stretch and the money it saved, plus what each slip cost, so one slip never hides the progress before it. Charts are part of Premium.

Quitzilla is a tracker for the habit you're quitting. When you add Smoking, you set when you last smoked and what it cost you, and pick your reasons to quit. From then on, the app counts your smoke-free time to the second, adds up the money you keep and shows how close you are to your next goal, from your first day to years from now. It doesn't replace advice from a doctor or a stop-smoking service.
You enter what smoking cost you per day, week or month, for example what you spent on packs. Quitzilla multiplies it by your smoke-free time, so the total grows every day. You can turn your savings into rewards: give a reward a name and a price, and the app shows how close you are to buying it.
Log it in the diary as a relapse. The timer restarts from that time, while your history and records stay, so you still see your longest smoke-free stretch. A short note about what happened helps you notice your triggers next time.
