I am very satisfied and amazed at the ability to monitor what goes on in the brain, stress levels, heart rate, etc. The option to use the unguided & timed meditation is worth it alone as you can use recorded guided meditation media from anywhere on the internet.

An impressive piece of technology! The app is fun to use and will amaze or surprise you with the well detailed feedback you receive from your meditation session. It's a perfect tool for medtation training.

I bought this to better understand my brainwaves when meditating. I get to see actual percentage of theta, alpha, etc. HRV is an added plus! All out together makes for good data when you are trying to get the most of your meditations as well improve your health.

Incredible resource for tuning your meditation! This is the perfect resource for monitoring your meditations. Since it builds a library of my activity, I can even reference all the metrics-over-time charts for my past sessions. Well worth the money!
