What Is Lyrio's Nuclear Option and When to Use It

The last resort for the hours when nothing else holds.

Lyrio TeamUpdated October 28, 2026

In shortThe Nuclear Option is Lyrio's last resort: it blocks every app and makes your phone unusable for 1, 2, 3, 4, or 8 hours, with no going back. Use it when the urge is too strong and Help wasn't enough. It's taking the decision out of the impulse's hands.

What does the Nuclear Option do?

It blocks every app on your phone for the length of time you choose. While the block is active, the device is practically unusable. And you can't undo it: once activated, it runs to the end. That's why the app calls it the last resort.

How to activate it, step by step

  1. Open the app's Emergency area. That's where the Nuclear Option lives, next to the Help button.
  2. Choose the duration. The options are 1h, 2h, 3h, 4h, or 8h.
  3. Activate the block. Tap the Nuclear button knowing there's no going back.
  4. Step away from your phone. Use the time to do something else: sleep, go out, read, talk to someone.

When is it worth using?

  • When Help and Quick Tips weren't enough.
  • During the risky times you already know, like late at night or when you're alone at home.
  • When you notice you're negotiating with yourself: "just one look," "just today."

Why does an irreversible block help?

At the peak of an urge, the impulse is great at arguing. A decision that can't be undone ends the negotiation. It's taking the choice out of the hands of the tired you and giving it to the you who will wake up tomorrow.

Which duration should you choose?

To ride out a wave of urge, 1 or 2 hours are usually enough. For the whole night, 8 hours: you sleep and wake up with your phone back. If you depend on your phone for something important in the next few hours, choose a shorter duration.

Frequently asked questions

Can you cancel the Nuclear Option after activating it?

No. It was made to be irreversible, precisely so the impulse can't undo your decision.

Does the Nuclear Option block only adult content apps?

No. It blocks every app and makes the phone unusable for the time you chose.

What's the difference between the Nuclear Option and App Control?

App Control creates rules for specific apps and sites in everyday life. The Nuclear Option is for emergencies: it blocks everything at once, for 1 to 8 hours.

Is using the Nuclear Option a sign of weakness?

No. Recognizing your own limit and acting before you fall is a sign of maturity in the fight.

You are not alone in this fight.

App blocking, community and a help button for the hardest hours.
