BlockSite vs LeechBlock NG

BlockSite

• Blocking the same sites and apps on a phone and in desktop browsers
• People who want to block whole categories of sites in one step
• Students and workers who block on a fixed daily schedule

LeechBlock NG

• People who want a free site blocker inside the browser they already use
• Rationing a site by time allowance rather than blocking it outright
• Users who want fine control with wildcards, keywords and regular expressions

BlockSite

• The web checkout showed rupee prices on the check date, so the subscription prices here are from the US App Store, which lists several amounts without saying which one applies.
• The privacy policy (last modified July 16, 2026) says browsing data is disclosed to affiliates for their market intelligence services; an opt-out is in the settings.
• Keyword blocking, unlimited category blocking and password protection need Premium, and the iOS app is for iPhone only.
• The homepage advertises a desktop app that blocks across several browsers but does not say which operating systems it runs on.

LeechBlock NG

• It blocks only inside the browser where it is installed; other browsers and desktop apps are unaffected.
• The developer says it is not designed for parental control or for blocking offensive content.
• There is no macOS or iOS version; the site points to ivBlock, a separate product based on LeechBlock.
• The browser may still connect briefly to a blocked site, so the developer suggests a HOSTS-level blocker when no connection at all is wanted.

BlockSite

Block List

Add the sites and apps you want to avoid, and BlockSite keeps them from opening while the list is active. Premium removes the limit on entries.

Focus Mode

Blocks distractions for a set amount of time. The Mac listing describes timed work sessions with scheduled breaks.

Schedule

Set the days and hours when chosen sites and apps are blocked, so the same routine repeats without being switched on each time.

Category and keyword blocking

Block a whole category such as social media or shopping in one step, or any address containing a chosen word. Both are Premium features on iOS.

Password protection

A Premium setting that puts a password in front of settings and blocked pages. The site also lists a feature that prevents uninstalling BlockSite.

Sync across platforms

The same block list applies on every signed-in device, and one purchase unlocks Premium on Android, iOS, Chrome, Edge and Safari.

LeechBlock NG

Block sets

Up to 30 sets of sites, each with its own list, days and times. Lists accept wildcards, exceptions and keywords that match words in a page's title or text.

Time periods and time limits

Block within fixed periods such as 9am to 5pm, after a time limit such as 10 minutes in every hour, or with both combined. Unused time can roll over to the next period.

Lockdown

Blocks the sites in chosen block sets immediately for a duration you specify, outside their normal schedule.

Delaying and password pages

Instead of a plain block, a page can show a countdown before letting you through or ask for a password. A custom blocking page can also be set by URL.

Access control

A password or a random access code can guard the options page, to slow down any attempt to change settings in a weak moment.

Temporary override

An optional override lifts blocks for a set number of minutes, with a cap on how many overrides are allowed in an hour, day or week.
