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!

It's been a month i guess since i started using this app. It's so colorful and full of positivity, whenever i open it, it makes me feel good. I recommended to everyone. It can help you finish some tasks in your life that you're too busy to finish, or help you achieve small goals, and developing new habits! Thanks alot!! :)

Using this app for the past 2 years and it has been a consistent reminder of how to maintain positivity and circle back when life gets challenging. Keep up the amazing work team. This app has been hugely impactful on my life ❤️

I love this app. i really struggle with consistency and a cluttered brain. This app helps me declutter my brain subtly one step at a time while teaching me consistency as a by-product. another thing I Love is after the end of 21 days, you can always find smth new to improve about yourself and the prompts are presented to you in your lap. Overall, an awesome experience !

I am really grateful to have found this app as this is what you want if you want to improve yourself, teach yourself consistency. It is effective in making you habitual to good things subtly and in a way you enjoy. I personally really like and appreciate this app. Highly recommend and thank you 21 days.

The constant pop-ups made me uninstall the app. Additionally, the design felt confusing and poorly thought out, with dark mode only partially implemented. I also found the app not very useful with the lack of focus on more practical habits. Overall, it wasn't a pleasant experience.

You guys have made life so beautiful with this app.. thank you and grateful. But I am not able to open reminder of the day, the one which you have to scratch and see.. it's such a beautiful feature, I don't want to miss it. kindly help.

I love this app. Even when not doing a challenge, it still sends a daily positive reminder each day. I appreciate that and try to pause a few moments when reading it to let it sink in.

I like the app, I find myself not really completing the challenges but I love the daily quote that pops up on my phone every morning. It's really encouraging.
