Curb.

What it does Curb flips habit tracking on its head. Instead of building new habits, you set daily limits on the ones you want to reduce, then stay under them. Every day you succeed, your streak grows. How it works Pick any habit you want to cut back on. Set a daily limit. Log each time you slip. Curb handles the rest: streak tracking, smart alerts when you're close to your cap, and detailed charts showing how you're trending over time. Key features
