Where BlockSite is better

  • Phone apps that block apps and sites on iPhone and Android.
  • One blocklist synced across your phone and computer.
  • Keyword and category blocking, so new sites in a category are caught too.

Where ZenTab is better

  • $10 once instead of a yearly subscription.
  • The free plan blocks 10 sites with no time limit.
  • Feed Eraser keeps YouTube search but hides Shorts and the home feed, instead of all-or-nothing.
  • A focus timer, ambience, New Tab and streak graph in the same extension.
  • Works without an account.

Is BlockSite free?

BlockSite has a free plan with limited blocking. Unlimited blocking, schedules and password protection are part of its Premium subscription, listed at $33.50 a year on blocksite.co when we checked.
