We thought we would answer a few questions about us and our projects that you asked us on our Instagram (@21daysapp) to get to know us better. We got tons of great questions! And we really appreciate you taking the time to reach out to us.

Here are the answers to some of your questions:

Who’s behind the 21 Days Challenge App (and blog)?

We’re a small team of 2 young adults, Kati and Lima. We have always been passionate about promoting well-being and positivity so we embarked on this project with all the love and we couldn’t be happier 😊

Where are you from?

Both from Portugal.

Where were you born?

Kati was born in France and Lima in Portugal.

What compelled you to take this initiative?

As we said, we have always been passionate about promoting well-being and positivity and we wanted to create something related to that, but we didn’t quite know where to start. Then one day the idea came up to create an app. We already had some experience with mobile applications, so why not?

On that day, one of us was reading a book on how it takes 21 days to form a new habit. That’s when there was a “click” on our heads, and the idea came up ✨

What is your biggest goal with the app?

What we want the most with our platforms is to help you create a life you love and become the best version of yourself!

When did you start?

In September 2019.

What came to your mind when you designed the app?

We always wanted something practical, simple, and minimalist. With a very clean and uncluttered UI. And easy to use! So, after a few attempts and improvements here and there (according to your suggestions too) we come to this final result.

Do you have other projects?

We decided to create a little store with some positive stickers. And we have plenty of ideas for new products in the future. But as I said at the beginning, as we are just two people it’s a bit difficult to manage everything and therefore the delay of new products in the store. But we’re working on that!

And we created this blog too. It’s a good way to write about topics we’re interested in and share our personal tips about personal growth, mental wellness, and lots of other things.

What keep you motivated to work?

You guys!! Seriously when we say that. All the feedback that we receive every single day. People sharing their stories with us and the way that we’ve managed to help them. That we changed their life for the better. That’s what keeps us going with our work. We have no words to express how grateful we are to have such a beautiful community. We couldn’t be happier!

What did you want to be when you were younger?

Kati wanted to be a vet (later she gave up on the idea when she knew she would have to give vaccines to the animals haha). Lima wanted to be an astronaut (well, I don’t think he would like it now haha).

What are your favorite hobbies?

Kati’s favorite hobby is photography and Lima’s cooking.

Which animals scare you most?

Kati is so afraid of spiders and cockroaches! Lima is also not a big fan of cockroaches haha

What was your first job?

Kati’s first job was at a travel agency. And Lima was a programmer.

Are you a morning person or a night owl?

We’re both a morning person.

Have you read any of the Harry Potter, Hunger Games, or Twilight series?

Kati is a huuuuge fan of Harry Potter and Hunger Games!!

Do you play any instruments?

We both play a little bit of guitar.

Are you spontaneous or a planner?

Kati is a planner and organization freak! Lima most of the time is spontaneous.

Have you ever seen a therapist? And why?

Kati did. She suffered from anxiety and panic attacks. Maybe that was the biggest reason why she started to be very interested in mental health (we can talk about her experience in a future post if you want).

What’s your main philosophy in life?

Everything happens for a reason.

Books or movies?


Do you have any pets?

Yes!! Kati has 5 dogs and 1 cat!

Where does happiness come from?

From within ourselves. It’s a choice at any given moment to think or to do something positive.

Do you think dreams come true?

Of course! Dream big, work hard and make it happen 🌟

What does success mean to you?

Success for us means having a stable life, full of love, work, doing what we like, and health. It’s also knowing that we make a difference in people’s lives 💖
