Use cases

Five situations, five different setups.

Blocking for a two-hour work session is not the same problem as blocking at bedtime, and a revision block fails in ways a gym block never does. Each of these says exactly what to block, what to keep, where to put the Bluetooth key, and the specific way that situation goes wrong.

The five

Start with the one you are actually trying to fix

Not all five. One situation, set up properly and used for a fortnight, beats five modes configured on a Sunday and abandoned by Wednesday.

Before you set one up

Four things that decide whether any of these holds

The same four mistakes turn up in every situation below, and three of them are about where the key ends up rather than which apps you picked.

01

Put the key where the friction is useful

Not the next desk — the next room. Far enough that fetching it is a decision, close enough that a genuine emergency is never a crisis.

02

Lock before you need to, not after

The moment to lock is when you sit down, not when you notice you have already lost twenty minutes.

03

Start with three apps, not thirty

A mode you actually use beats an exhaustive one you abandon. Add the rest once the habit holds.

04

Pair it with something you already do

Lock when the kettle goes on. Lock when you sit down to eat. Attach it to a trigger that already exists.

All four are downstream of one fact: locking is free, instant and works with Bluetooth switched off, while unlocking needs the key physically within radio range of your phone. If you want that mechanism rather than the situations, how it works explains it, and the guides go deeper on method than any of these five pages do.

One situation at a time

A mode you actually use beats an exhaustive one.

Set up one situation, use it for a fortnight, then add the next. Locking stays free and instant either way — the key is the one-time buy, and where you leave it is what decides whether any of this holds.
