Overcoming addiction is hard. With Quitzilla you can follow all of your bad habits or addictions and use the app as help to analyze them and beat them. Stay clean and sober, overcome any addiction or habit which is holding you back from becoming a better version of yourself. BAD HABITS TRACKER Commit to quit "cold turkey"! You can add the exact day of the last time you did it, the money you usually spend on it, and let it serve as your starting point. From then on you can get tons of interesting statistics about it. The abstinence time and money saved are the leading statistics. REWARDS The rewards feature is actually a calculation of the money saved.

About

Features
Read full description

Thinline is a private Christian sin tracker. No account. What you write stays on this phone. You name what you track. Tap to acknowledge. Swipe when you held back. Optional short notes. Charts and a journal show what actually dominated — no streaks, no scores, no partner feed. Resist is one tap away when awareness isn’t enough: Reset, Move, and Story to interrupt an urge. Examination of Conscience is a session-only examen; answers are not saved. Optional App Lock uses Face ID or your device passcode. You can export a backup you control. Thinline requires paid access. The Founders Offer is selected whenever it is available; annual is the fallback. Eligible customers may receive a three-day monthly trial or seven-day annual trial. The Founders Offer is an immediate one-time lifetime purchase with no trial. Restore, export, and delete remain available without a subscription.
