A complete list of features on Otto. Otto has two main features - A focus timer and website blocker. The philopshy behind the design of the app is less is more. So we don't try to cram as many features as we can.
We've realized that rather than adding more pointless features, just focusing on 2 main ones and then adding additonal features only to enchance them is a better choice for Otto.
It also keeps the app lean and avoids decision fatigue, and Otto as a product becomes focused rather than an everything app.
We believe the essentials should be accessible. Otto's primary features — the focus timer and site blocker are free for everyone. Our additional features act as enhancers for the core experience, available for users who want to unlock Otto's full potential.
