It’s effective. Buggy, but effective. – Brain.fm - Focus Music Review

Overall, I like the application and serves it’s purpose. Yes, like many other reviewers I’ve had connectivity issues now and again. Downloading seems to never work for me either. That said, it’s also hard to imagine these are AI generated sounds. Many of them sound very similar to YouTube recordings that I listen to. With that behind me, I will tell you that I am much more effective in my work with headphones in and listening to the focus music while I’m working. I switch between different focus themes or sometimes allow the app to select for me. At times I can listen to it through speakers on my computer, however I will reluctantly admit it’s more effective with headphones. As a result, I purchased a lifetime membership. I anticipate it will improve significantly over time and they will continue to add different types of music/sounds.
