wanna scroll? do 67 first. 67 blocks the apps you open without thinking. to get in, you do the 6-7 gesture, hands in the air, counted by your camera. then 67 asks: still wanna scroll? say yeah, and the app opens for a few minutes. say nah, and it stays blocked. either answer is fine. the point is that you chose. HOW IT WORKS • pick the app that eats your time. • open it, and 67 is there instead. • prop your phone up and do the 6-7 gesture. • 10 reps for 5 minutes, up to 67 reps for 20. or back to your day. • the block comes back by itself, even if 67 is closed. NEW HERE? 3 DAYS OF 67+, FREE every new phone gets 3 days of 67+. no card, nothing charged when it ends. after that, keep 67+ or pick 1 app to keep blocking for free. FREE, FOREVER • 1 blocked app. you choose which. • blocking hours: block all day, or only the hours you pick. • pausing the block takes a 67 too. • no ads. no account. 67+ • all your bad apps: unlimited apps, plus categories and websites. • locked in: lock your own rules for 30 minutes, 1 hour, 2 hours, or until morning. while you're locked in there is no pausing, nothing comes off the list, every unlock takes 67 reps, and no app on the phone can be deleted. there is no undo until the time is up. 67 never charges you to weaken your block. PRIVATE BY DESIGN • camera frames are processed on your phone. nothing is saved or uploaded. • 67 can't read the names of the apps you block. apple keeps them hidden, from us too. • no account. usage stats are anonymous. 67 needs screen time access, which ios will ask you for, and the camera. iphone only. 67+ is a one-time purchase of $29.99, or an auto-renewing subscription: $19.99 a year or $4.99 a month. prices vary by region. payment is charged to your apple account at confirmation of purchase. subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. manage or cancel them in your apple account settings. terms: https://do67.app/terms privacy: https://do67.app/privacy

Verdict
The clearest difference is monetization model: Lerf at free against 67's free with in-app purchases. Lerf also leads on ratings volume (15 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Lerf sells 5 in-app purchases, starting at $3.99 per 7 days and 67 sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Lerf against 5.0 for 67. That said, the two scores are not equally well evidenced: Lerf has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Lerf ships an update every 5 days, 67 every 4 days. Both last shipped on October 31, 2026.
