ZenTab vs StayFocusd

StayFocusd, made by Sensor Tower, has been helping Chrome users limit time-wasting sites since 2010. It's free, and built around daily time allowances and its well-known Nuclear Option. ZenTab is a Chrome extension that blocks distracting sites, hides endless feeds and turns focus time into a streak, free to start with a $10 one-time Pro.

Frequently asked questions

Is StayFocusd still free?

Yes. When we checked, StayFocusd was free on the Chrome Web Store, including the Nuclear Option and time allowances.

Does ZenTab have something like the Nuclear Option?

Yes. ZenTab Pro's Nuclear mode blocks every site except the one you're on until a timer ends, and commitment locks keep Strict Mode on until a date you choose.

Can I use both?

You can, but two blockers can show two block pages for the same site. Most people pick one.
