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!

I really like the premise of this app and I've enjoyed the few excersizes I have done so far. My only complaint is that everytime you complete a task, it says "Cancel" in grey or "Share" in bright yellow. It really takes away from the rewarding feeling to have to just say "Cancel". If it said "Complete" or something more satisfying I would give 5 stars. Also white font shouldn't be on a yellow background because it makes it difficult to read.

I like the app, I did pay to go ad free. However, when the blog link is followed, there are ads there & what I just found disturbed me. There were 3 ads for "what to do if he's gone cold", what to text him, etc. "to get him back" in a post for self esteem which includes advice like don't sell yourself short, accept you the way you are, and more.

This app has really helped me to develop better habits & routines, as well as become a more motivated & positive person. It's also gotten me to start journaling again, which has proved to be very eye-opening. The only complaint I have is that there's no eyebrow customization; you can customize your eyes, skin, mouth, hair, etc., but not the eyebrows. You're stuck with the default eyebrows, that are quite frankly, a bit ugly. If new eyebrow options are added, this would be a 5 star app for me!

I love everything about this app! It's very motivating to do my daily challenges plus the blogs are always reassuring. This app makes me look on the brighter side and helps improve my attitude too! The only downside is the character options you can choose from are a little silly. For ex. Some of the facial expressions and the hair styles aren't very realistic. Maybe try having more of a variety for each category and adding new options that we can use our coins for would help.

This app has a positive impact on my life. There's so many categories to implement small but powerful acts of self-care to my routine. Especially during a pandemic, when social isolation increases, this app reminds me of ways to use my time to better my life. I've started working out again little by little due to the fitness portion, and tapped back into art, music, meditation, and taking baths. The positive affirmations are useful for reframing my mindset. I highly recommend giving it a go!

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!
