Excellent hunting @evelynbelle, this is very useful for people who have a hectic pace of life, I will leave my personal opinion about this hunting.

Pros:

• Excellent application for people with little time.
• In addition to meditation exercises bring a breathing exercise kit, perfect for people with respiratory diseases.
• It is totally free and you do not need internet to use it.

Cons:

• It's something heavy (125.9 MB).
• Currently only compatible with iOS devices.
