Lerf
Block distracting apps.
Go do something else.
Make your phone a tool again with Lerf.
Put your Lerf Tags where the distractions start:
- Desk
- Nightstand
- Fridge
How it works
Choose apps
Select the apps you want to block within the Lerf app.
Tap your Lerf Tag
Activate your session by simply tapping your phone against the Lerf Tag device.
Live in the moment
Turn your phone back into a tool that supports your goals.
The physical device that puts you back in control.
Tap to disconnect from distractions and take back control of your time. No overrides or workarounds, just uninterrupted time until you’re ready to unblock your selected apps.
What makes Lerf Tag different
You can’t just hit “Ignore Limit”.
With other solutions, the “key” that re-enables distractions is always within reach.

Early user reports
95% feel less distracted.
Of early Lerf users who reported back. Here's what that looks like:
Deep focus
Work starts with a tap instead of a negotiation. The pull is gone because the door is locked.
Real sleep
The phone goes to bed before you do. Nights end with a book, not a feed.
Time with people
Dinners and evenings where you're actually there — present, not half-scrolling.
Real reviews, real results
“It is instant peace. Nothing makes me feel better than staying off my social media, especially when I’m trying to get work done during the day. It’s super easy to use and I love the Lerf tags — I have them in different spots which makes it super easy for me to lock my phone down.”
“Literally life changing. Has helped me work and sleep better.”
“Thank you for making this. It has helped my anxiety so much.”

“Lerf has had a very positive impact on my life. I feel more focused, less stressed, and overall in a better mood.

Where people put it
Stick it where the scrolling starts.
- On your laptop, so focus travels with you.
- On your fridge, so dinner is peaceful again.
- On your nightstand, so your phone goes to sleep before you do.
- On your desk, for deep work sessions and focus.
- On a book, for uninterrupted reading.
- By the front door, so outdoor activities can be enjoyed to the fullest.
The Lerf Tag turns into an intentional decision to disconnect and simply live in the moment with a single tap.
The app
Works with the Lerf app.
Lerf is an iPhone app blocker built around relief instead of streaks and scores. No account. No dashboards. Nothing to check. Lerf can't see which apps you block or how you use them. Lerf Tags are the app’s physical half — learn more about the app or get it below.
Frequently asked questions
What is Lerf Tag?
A small tappable disc that starts a Lerf app-blocking session when you tap your iPhone to it. Tap once, put your phone down, and your chosen apps stay blocked for the session.
How does it block apps?
The Tag triggers the Lerf app, which uses Apple's Screen Time framework to block the apps you selected. Tap the Tag, tap the banner that appears, and your session starts. An optional one-tap setup in the app's settings removes the banner step entirely.
Does it require a subscription?
No. The Tag is a one-time purchase that unlocks the Lerf app. Without a Tag, the app is $14.99/month or $79.99/year after a free trial.
Is it Lerf or Lurf?
The app is spelled Lerf, L-E-R-F. Some people hear or search for "Lurf app," but Lerf is the iPhone app blocker designed around short sessions and relief.
Can't I just delete the app to get around it?
Yes. Deleting the app is a deliberate, multi-step act — a cooling-off period, not a reflex. The Tag exists to beat the unconscious tap, not to imprison you. Most people put the phone down instead.
When does it ship?
The first batch is rolling out now. Orders ship within 5–7 days, and every Tag is prepared by hand.
