So I was forced to sign up with a quit website through checks notes New South Wales, Australia.
Seriously, how hard is it to have a simple website that can track quitting something? Not everything has to be a stupid app on your dumb phone that spies on you.
I use Table habit which is open source and available on fdroid and works on other platforms as well. There are other options on fdroid like habit mamer, grit, habit builder, kokudo, loop habbit tracker, habo, habits and githo which are free open source and don’t spy with optional sync options. I think you can also self host habitica. You can download the apk and install through adb on android. Apple has other ways and on pc there are plenty of options on linux. Bupropion and tapering off with puff count should help.
