If you don’t have this app your missing out! ### 5/5 — Very good app *2023-11-17, version 3.6.3* Lots of great content ### 5/5 — Opening day success *2023-11-17, version 3.6.3* I have been hunting my whole life but have been following Marlon for a few years now. Learning as much as I can from his podcasts and story’s, his wisdom goes far beyond hunting and goes deeper into the meaning of life and success. That being said, I knew the app would provide great knowledge and it would be worth it to support him. I found a big buck back in August and went back in opening day and sure enough he was right where I left him. But I had two miles to cover where I would lose sight of him. Marlon talks about trusting your instincts and to assume that the buck is going to be where you left him and to close the distance in confidence. I started making my way in losing all sight of him and finally got in close and peaked over the edge and sure enough, there he was. I came in from the top and absolutely hammered him! So thank you for your great advice and knowledge, it helped me hammer an amazing buck! ### 1/5 — Money hungry *2023-10-19, version 3.6.3* I bought the app. I wanted to try it out for a month. I stopped my automatic renewal just incase I forgot and the cancelled my subscription. So I paid for the whole month and get 3 days…. Emailed them. Never responded. ### 5/5 — Knowledge worth more than any $$ amount *2023-08-19, version 3.6.3* This app is absolutely incredible!! The knowledge in each section comes from years of actual experience. There are so many topics covered in this app that aren’t normally spoken about. If you want to hone your craft this is an amazing way to keep learning with continuous additions to modules. You won’t regret it. Knowledge is power and can help you stay on the mountain and do the things you love more than ever.
