Create your ideal life with life changing habits.
It is estimated that it takes people 21 days to form a new habit. So it’s a perfect amount of time to change or introduce something new in your life. Choose the best challenge for you and do it for 21 days and you’re going to see how the habit becomes part of your lifestyle day by day.

Starting a healthy lifestyle, taking a break away from the internet, practicing gratitude, trying to be more productive, simple practices to find happiness and calm in your life, how to study effectively for all the students, ways to spread kindness and positivity, tips for fixing your sleeping schedule and daily positive affirmations are some of the challenges that you can find in the app.

Once you complete your daily task, you can mark as completed and collect the points (to customize your avatar). This way, you can use this app like a habit tracker.

In the gratitude challenge, you can write your thoughts and share them in the feed (you can leave anonymously too). Here you're going to see all the community answers and you can also give it a like on your favorite ones.

Complete tasks on your profile and do daily challenges to collect points so you can buy items for your own avatar like different hairstyles, eyes and mouth shapes and clothes.
Create a healthier and happier mind with journaling. With this app you can daily journal and choose your daily mood. Then you can track your mood in the calendar and see all your previous records.
You also a have a selection of positive wallpapers for your phone.

Enable notifications and choose the time to be notified to remind you to do the challenge every day.

Don’t forget to take care of your body and mind. It's the only place you have to live.

Great app

This app is awesome. I really enjoy doing the challenges that the app provides.
I’m currently doing self-care (day 13) and kindness (day 7) challenges. The daily challenges are like little implements for starting new things. One of the challenges for today it was write a nice and positive review for your favorite app; here I am (:
The reminders for the challenge that you do aren’t the same, nor do they make you feel like another have-to-do’s/ chore. Instead, they’re motivating and positive. The one I received today was “don’t be afraid to start over and try again. (: “ I am grateful to come across this app. The creators make a great impact on those who use this app and I’m grateful to be one of those people.

Love it!

So, I don’t have anything to complain about this app really, I love it so much! It’s so calming and simple. I have been excited to wake up each morning and scratch off my daily challenge each day, I am currently working on the challenge “positive mindset” as I currently just went through a lot of body shaming and self love issues that I’m trying to recover from! If you read this before you get this app, I highly recommend it for you friend! It keeps you organized, and eventually you will become the healthiest, happiest, version of yourself you will could possibly want to be! :).

Thank you! Great app

I love this app. very encouraging and i shared this app with mom and other friends. This is the perfect app during this pandemic. Thank you for creating such a beautiful app. But it would be nice in the future if you don’t want to do the challenge to switch or flip different options since each person view some task big or not ready to start with. But I LOVE everything about it including Journal daily and make your challenge!! YESSSS! GET THIS APP!!!
