Habit Starter is about starting new habits to get things done and improve your life.
Each day you report on whether you succeeded yesterday, building up streaks of the habit and ingraining the activity 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)
To get started just open you habit list and tap Add. Now add your habit, for example 'Exercise'. Set a low, achievable goal giving details in the description.
Now every day simply report on whether you achieved this (and how easily). Every day you do it adds one to your streak. But if you miss a single day it is reset.
You can enable a reminder on your iPhone via the main setting menu to ensure you report regularly. This serves as both a reminder to do the habit and as a prompt to report daily.
