you need this if you have "focus trouble" and use stage manager with an external display
i love using stage manager with a second screen but sometimes you really need to focus on one thing and not get distracted and either duplicate the displays or find something for the other screen that won't distract you - something more conducive to focusing on the other screen. even the home screen makes it hard when i'm trying to focus on on my writing. this app though? it's absolutely perfect. you can set it to a flowing pattern with no beat if you're listening to stuff with complex time or if you're listening to a big long trance mix you just put the beat in and you're good for as long as the music goes. now when you look at the other screen there's a soothing mathematical that helps you become more focused instead of less, and you can look at the monitor that's set up for your optimal neck posture when typing i figure this would also work with someone with adhd but all i know is it works for me and i have a dissociative disorder oh but please make sure to read the actual description on here because the app itself will not tell you how to set a beat!
