"After a few days you'll have a chain. Just keep at it and the chain will grow longer every day. You'll like seeing that chain, especially when you get a few weeks under your belt. Your only job next is to not break the chain" (Jerry Seinfeld)
Habit Streak has two key advances on Jerry Seinfeld's original technique. Firstly it allows you to build several chains up at once. Secondly it (optionally) prompts you every day to report on your success (whereas one could easily forget to update or look at a physical calendar).
✓ Habit Streak is simple, clear, easy to use and free; there are no time limits (there is a Pro version with some additional features for power users).
