How it works

Build your own challenge or join a curated one. Either way, you're five steps from a limit that holds.

1

Pick your apps

Choose the apps you want to limit — or start with a curated challenge.

Select apps screen
2

Set your limit

Set one daily allowance for the apps in your challenge. Lock On tracks their combined use throughout the day.

Set time limit screen
3

Set your Overtime Rate

Choose what 15 minutes of overtime costs. When your limit runs out, your apps block — call it a day, or spend focus credits to continue.

Set overtime rate screen — credits per 15 minutes
4

Choose your duration

Choose a week, a month, or your own finish line. Every clean day builds your streak and moves you toward a stronger trophy.

Set duration screen
5

Confirm and lock on

Review your terms and start. Tighten them anytime. For easier changes – wait 48 hours. Or lock the challenge so it cannot be paused, loosened, or ended early.

Confirm challenge screen

Pause before you scroll

Lock On puts a speed bump before distracting apps, warns you as the limit gets close, and blocks them when time is up.

Under the limit — Lock On asks if you really need the app

Still time on the clock

Open a locked app and Lock On asks if you really need it — with minutes left shown so you stay accountable.

At the limit — the app is blocked until you buy overtime

When the limit hits

The app stays blocked. Buy 15 minutes from your Focus Reserve, or go back — every extra minute costs you something real.

Finish a challenge, earn a trophy, and see the days you actually stayed within the limit.
