I got a lifetime subscription for 90% off from a link posted on HN when brain.fm first started.

Anecdata: it is probably one of the best purchases I've ever made for workplace success/productivity. The focus music works (light focus in the app) and has served to block out workplace sounds, improve focus, and not be distracting in and of itself - normal music seems designed to induce various emotional states that aren't helpful for work or thinking clearly.

I think it's worth giving a try, and if it works for you then it's worth paying for. The app is certainly a lot better than it was at the start, and offers more options than the browser interface.

I don't find the sleep sounds so useful but a 15 minute 'chill' relax sound was often helpful when trying to get from a stressful state of mind to a calmer one, usually when going home from work.
