Otto works really well for its intended purpose, and it's helping me fight my internet addiction and make better use of my time. The UI is very simple and clean, and the illustrations are adorable. It's very helpful all around!

Simple but effective. Easy to customise, nice passive incentives. It does exactly what you're asking of it and it does it well.

After using this for a couple months, I really don't have anything negative to say about it. Otto does exactly what it is designed to do, block distractions and help you be more productive. Even without the upgrade, it still works well to boost productivity.

Simple, reliable focus tool. I've used it long-term for blocking distracting sites and timeboxing work. It does exactly what it promises without unnecessary complexity. Solid option if you want fewer decisions and more follow-through.
