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! ### 5/5 — Jada *2016-05-30* 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! ### 5/5 — Relax Refresh Rewire *2014-12-28* Meditation is a great way to start and/or end your day and this app leads you through multiple exercises. Helps with calming, planning, quieting your mind, finding inner strengths, coping, and building a repertoire of inner thoughts to help manage distractions throughout the day. Nature-themed visuals allow you to keep track and earn rewards. Love it! ### 5/5 — Wonderful app for all ages *2014-11-16* 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. ### 4/5 — Great app *2014-11-16* Great app for focusing your mind and body in the morning before a long day. I find myself feeling at peace after using it. Sometimes it helps me calm down during the middle of a long work day. ### 5/5 — Find your internal Peace *2014-10-30* Peaceful, Reinvigorating and Powerful!! Reminded me of the gentle face of Malala speech after receiving the Nobel Price of Peace spreading words of hope, courageous and peace!! ### 4/5 — Mellow and fun *2014-09-27* I've been "playing" for a couple of weeks. I like the fact that you can relax and calm but also get things like the boots and the leaves on the tree. ### 5/5 — Perfect for college students!! *2014-09-26* This is exactly what I needed! I have ADHD, and this app not only helps me de-stress when I get overwhelmed by classes and essays and exams, but also improves my ability to focus and be productive (aka something I majorly struggle with) when I do sit down and try to tackle my schoolwork. ## Frequently asked questions about 3rdi ### What is the learning methodology of 3rdi? 3rdi combines mindfulness techniques with neuropsychological principles.
