No subscriptions. ### 5/5 — Amazing *2025-08-28* I’ve been using BrainGamma40Hz for a few weeks now, and it’s become an essential part of my daily routine. Whether I’m meditating, winding down before bed, or just taking a break during a stressful day, this app helps me relax deeply and feel more balanced. Highly recommended for anyone looking to improve focus, reduce stress, or just find a few moments of peace in a busy day. ### 5/5 — It actually helps! *2025-08-16* Had one of those stressful days at work and decided to try as soon as I closed my laptop. I set 10 minutes and I could feel my my mind start to quiet down. Before bed, I used it other 15 minutes in alpha meditation with transitioning light, and it was the perfect way to wind down. The light paired with the gentle sound really eased me into sleep mode. Slept so much better. Highly recommend for anyone who needs a mental reset after work. It will stay in my routine. ## Frequently asked questions about BrainGamma40Hz ### What is BrainGamma40Hz?
