Habit Streak was selected alongside apps from the BBC, Guardian and Sky as a British Favourite by Google. It has also been featured on Google's front Android store page, by Lifehacker, selected as one of MakeUseOf's Best Android Apps.
Habit Streak helps you achieve your goals (or New Year's Resolutions) in exercise, diet or other areas of your life. Each day you report on whether you succeeded yesterday, building up streaks of habits and ingraining the activities into your life.
"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).
