STOP and read first. – Unblue Review

Don't be like me. Don't be an idiot. Stop and read the description before you pay $3 for this. It's not f.lux. It's a neutered browser that does, in fact, filter daylight portions of the light spectrum. But again, it's not what you want; It's not f.lux. So probably don't buy it. 4 thumbs down.
