I've been a user of the Typeboost desktop app for quite some time and it has helped me tremendously beat procrastination. I can no longer imagine writing anything without the subconsciously motivational music playing in the background. I used to struggle with taking long breaks between each sentence I wrote, leading to the simplest of essays taking much longer than needed. Typeboost helped eliminate that.
I've been using Typeboost to write a lot and its made the experience much more enjoyable, especially with the new desktop app giving me the power to write in any application. Support is great and I'm excited to keep using the product.
