Details

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 (or create your own) 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, learning a new language, trying to be more productive, finding happiness, self-help, how to study effectively, ways to spread kindness and positivity, tips for fixing your sleeping schedule, self-care practices, decluttering, being more confident, writing journal prompts and daily positive affirmations are some of the challenges that you can find in the app.
Basically, you can use this app as a habit tracker.

Once you complete your daily task, you can mark it as completed and collect the points (to customize your avatar, to unlock motivational reminders and free wallpapers).

In the gratitude challenge, you can write your thoughts and share them in the feed (it can be anonymous too). Here you're going to see all the community answers and you can also give it a like, comment, or send gifts to your favorite ones.

Create a healthier and happier mind with journaling. With this app, you can write a daily journal and choose your daily mood. Then you can track your mood in the calendar and see all your previous records.

There’s a selection of positive wallpapers for your phone and motivational reminders to share with your friends. Also, some relaxing music. 

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

You have all of this in one app for free!

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

Your journey to self-improvement and better mental health starts today!
