Otto
Pomodoro timer and website blocker extension for Chrome
What is Otto?
Otto is a Chrome extension that pairs a Pomodoro-style focus timer with a website blocker. Sites on your blocklist are blocked while a work session runs, and the blocker can also run on a schedule or apply time limits instead of blocking outright. The timer and blocker are free with limits on the number of rules, and Otto Pro, sold as a one-year or lifetime license, removes them.
Otto has a free plan. Paid plans start at $29 for a one-year license, or $66 once for a lifetime license. See every plan
Good for
- People who do most of their work inside Chrome
- A Pomodoro timer and a site blocker in a single extension
- Buyers who prefer a lifetime license to a subscription
- People who want a gentle, game-like nudge instead of a hard lockout
Worth knowing
- It is a Chrome extension: there is no desktop or mobile app, and the vendor gives no date for the mobile app on its roadmap.
- The free version caps scheduled blocking at 2 rules, autoblock at 1 rule, the task timer at 3 tasks of 15 minutes and analytics at 7 days.
- The one-year license does not carry on: when it expires, Pro features stop and the extension drops back to the free version.
- There is no free trial of Pro, though refunds are given within 14 days. The web version is a plain timer without blocking.
Key features
- Pomodoro focus timer
- Work and break intervals with lengths you can change and no cap on sessions. Pro adds a reverse work and break timer and a strict lock on the timer.
- Blocking during focus sessions
- Sites on the blocklist are blocked whenever a work session is running. Sites can be added in one click and unblocked temporarily when you need them.
- Scheduled blocking
- Chosen sites can be blocked at set hours and on set weekdays without a focus session running, and rules can target specific URLs instead of a whole site.
- Autoblock time limits
- Instead of blocking a site at once, Autoblock starts a countdown and blocks it when the time runs out. Each rule has its own duration and the count syncs between tabs.
- Task timer
- Naming a session turns it into a task timer with an in-browser to-do list, single-task and sequence modes, and a record of the time spent on each task.
- Analytics and the Otto character
- Focus and distraction analytics cover 7 days on the free version and all time on Pro. A game mechanic builds a bond with the Otto character as you focus.
