About this app

Ever wondered how long does it take to break a habit?

Scientists and leading psychology research suggest that it takes us around 21 days to break or form a new habit.

This means doing a good thing (eating clean, exercising daily) can become your habit if done 21 days in a row.

And Bestselling Book “Power of Habit by Charles Duhigg” suggests that an old bad habit cannot be extinguished in a day, but can only be replaced with a new good habit in 21 days period.

So if you want to Quit Smoking? Lose Weight by eating clean? Quit eating junk food? Exercise daily? Go to Gym daily?
Just do it for 21 days straight and our app allows you to record your golden age of lifestyle transformation.

How does it work?

To transform your lifestyle and create new good habits :
Add a new goal that you want to pursue

**update** the app has been updated and seems to be working great now. I was using the app fine for a few weeks; it is simple to use and the reminders are helpful. But despite the requested time for a reminder, I have started getting reminders much too late in the day. At first it was just off by an hour or so but lately I have been getting notifications for all my goals at the same time at the end of the day.

I like the app but it's a little basic. It would be great if there were the beginning and end dates. Also the share icon would be nice and section where you could journal for each date. This is great if you want just track days but changing habits is a process and it would be great to have all these options in one app to document the journey.

1) You should remove the necessity of adding a reminder while adding a goal. For eg. If someone have to add a goal of not doing something for 21 days, why they will add a reminder of that thing. So that's why I think the reminder thing should be optional. 2) The color of the tick icon of the goal should change from grey to green when we click on it, but it does the opposite. 3) In case I mistakenly click on the tick of a goal it adds one day completion of that task, and I can't undo my actio
