3rdi combines mindfulness with neuropsychology to give you a simple yet powerful tool to become more focused, alert, and centered.

The app features 15 unique exercises that are divided into three progressively deeper levels of concentration. The first step is to learn strategies to feel more calm and centered. Then we do more reflective exercises to look for patterns in our thinking. Finally, if you find an outdated mental habit or a trait you wish to alter, we learn how to adjust ourselves in a gentle, non-judgmental way. As you complete the levels, you will gain prizes for your avatar. However, you experience the real rewards in every day life.

Welcome to the journey - we're glad you're here.

Ratings and Reviews

Good App


I am 14 years old and am just starting high school. I like 3rdi because the meditations are peaceful and calming. They help me when I feel anxious or stressed out. I also like the visuals on the app because they are unique. However the instructions are a little confusing, especially in the beginning. When I first downloaded the app, I didn’t know what to do exactly. And I wish you could change scenery without having to finish a whole set. Other than that, I say 3rdi is a great mindfulness meditation app!



I found this app through Instagram and am so happy that I did. I am 11 years old and use this app when I am tired from school and swim. The meditations calm me down and also give me energy to get through the week!

Wonderful app for all ages

Calmer grandmother

This app has so many benefits for people of all ages. I am 76 years old and was curious when my granddaughter was playing it. I tried it and was amazed at how quickly I could find the concentration I have sought for years. I find the float "down the stream" so effective. I find the sensation carries with me even if I am not on the site. It is a wonderful reminder to put my worries and fears on the shore for a while. I hardily recommend this app to anyone who wants to be a calmer more focused person.
