About this app

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!

This app is simply amazing! It's encouraging and rewarding. I love that it gives daily quotes, gives out coins only to accessorize the avatar (effective reward-system) and has a challenge for EVERY day. There are a few spelling/grammar errors on some of the challenges, but it is still clear what they're saying. The app is simple, the challenges are wonderful and encouraging (I've completed 5 sets and only now decided to review), and the system is successful. Thank you for your work, Kita & Lima!

The app is so complete and easy to use! It has everything you could need. Everyday it has new challenges for what you want. If you can't find something you need or want you can make your own challenge and even set the challenges for each day, or keep the same one (like a particular exercise). If I had to make one suggestion I would say add a journal so it's all in one place. I look forward to starting more challenges soon!

I freaking love this app so much! I use it for starting habits and breaking bad habits. Over all I would say this app has helped me so much during quarantine. The one thing I would change though is that when I finish a task I would like it to go on a separate page. Like I want all my unfinished tasks or ones I haven't started to be on a page of its own while the ones I have finished are on a completely different page.
