Reddit is uniquely good at eating time because it never runs out. Finish one subreddit and there's another. Finish the front page and there's a comment thread. Unlike a single article or video, there's no natural stopping point built in — the scroll just keeps generating more, and "one more post" can go on for an hour without you noticing.
If you've opened Reddit "just to check one thing" and looked up 45 minutes later, this is why. It's not a discipline failure — it's a product built to remove stopping cues.
Blocking Just Reddit Isn't Always Enough
A lot of people try browser extensions that block reddit.com specifically, which works until they open a different browser without the extension, or until old.reddit.com or the mobile web version slips through a domain rule that wasn't specific enough. Reddit also has a lot of subdomains and redirect paths, so a narrow blocklist can miss edge cases.
A Cleaner Way to Block It
Lock In! blocks Reddit at the system level on Mac, covering the main domain and its variants across every browser you have installed, not just the one where you set up a rule.
Add It Once, Blocked Everywhere
Add reddit.com to your blocklist — or use the Social or Entertainment preset, which already includes it — and it's unreachable in Safari, Chrome, Firefox, and Arc simultaneously. No per-browser setup.
Blocks the App Too
If you use the Reddit desktop app or a third-party client wrapped as a Mac app, Lock In! can block that directly with a full-screen interrupt, closing the gap that a website-only blocker would miss.
Scoped to When You Need It
You don't have to block Reddit forever — most people don't want to. Run it during work sessions with a timer, and it opens normally again once the session ends, so browsing on your own time is unaffected.
Strict Mode for Honest Days
If you know a five-minute Reddit break tends to become fifty, Strict Mode removes the option to end the session early. The block holds until the timer says it's over.
The scroll ends where the block starts. Get Lock In! on the Mac App Store
