Darren Marks is really is the best on here! Seriously. Read the prior reviews. I looked for the best one and am confident you will be pleased with the results. He has the perfect voice for this kind of stuff, a British accent that doesn’t sound slicked over or contrived like those cheesy audio tapes you’ve probably heard. Make sure you listen with headphones so you’re completely immersed in the audio. It really works. You must stay consistent with this, it’s like going to a gym, you gotta stay focused on the goal. I bought the others he offers even though this app comes with a few extras because I was interested in the confidence ones as well. I personally guarantee you will be 100% satisfied with your purchase.
