Valeriy Kovalenko

Welcome! My name is Valeriy Kovalenko, I’m a freediving instructor of Apnea Academy and the creator of the STAmina Apnea Trainer. I would like to thank you for using the app. It is the product of a beautiful team of professionals. I hope that you find it helpful and use it regularly to get better breath-holding skills. If after reading the documentation you still have questions, please feel free to contact me by email or on Facebook.

If you haven’t installed STAmina yet, you can grab your copy here: for iOS, for Android.
