# go-hyperfocus > Work-In-Progress: Do not use this software. It doesn't work yet. I haven't even compiled it once, so there are likely to be logic errors, and some features aren't fully implemented. Block distracting websites and hyperfocus on your tasks! This is a Go implementation of the Python-written [concentration](https://github.com/timothycrosley/concentration) program. This program aims to be memory-efficient and to allow the user somewhat more freedom in defining distractors than its predecessor.
