Knowing isn’t the problem.
The moment is.

When it comes, your phone is louder than your plans.

Mast

You want to read for 20 minutes every night at 9:30 PM.

You tell yourself: “Just 10 more minutes.”
Then: “I’ll start tomorrow.”

Tomorrow comes, and so does the same excuse.

So Mast does it for you: at 9:30 PM,
it locks your laptop for 20 minutes.

Now your apps won’t open until 9:50 PM.

It’s just you and the book.READ THE BOOK.

You want to be asleep by 11:30 PM.

You tell yourself: “One more video.”
Then it’s 1 AM, again.

And the next morning, you’re tired again.

So Mast does it for you:
at 11:30 PM, it shuts everything down.

Now nothing opens until 6:00 AM.

It’s just you and sleep.GO TO BED.

Why it works

Tie yourself to the mast.

Odysseus knew he couldn’t resist the Sirens’ song. So before his ship sailed past them, he had his crew tie him to the mast, and told them not to untie him, whatever he said.

Mast works the same way. You decide when you’re calm. It holds you when you’re not.

Held, gently. You won’t drift.

Here’s how it holds you.

When it’s time to focus.

The meeting you blocked for deep work starts. Mast locks the apps you chose until it ends, on your phone and your computer.

When it’s time to sleep.

You meant to stop at 11. At your bedtime the computer turns itself off and the phone goes quiet until morning.

When it’s time to pray.

If you pray, your phone and computer lock a few minutes after each prayer time. Go, and come back to them.

When you really need out.

Ask a friend you chose. When they say yes, you’re out. Or use your one emergency a week. There’s no setting to switch off in a weak moment.

Get Mast.
