App blocker guide

Stackwall is an app blocker for the apps you open on autopilot. It blocks selected apps with Screen Time, opens a phrase-based pause, and lets you earn a short temporary pass when you choose.

## Block the apps that pull you into a feed

TikTok, Instagram, YouTube, Reels, and Shorts can be useful. They can also turn a quick check into a long, unplanned session. Start by blocking the specific apps or categories that cause the most unwanted use.

Stackwall uses Screen Time for app blocking. When you try to open a blocked app, Stackwall opens in its place.

## Tap a phrase before you unlock

In the default mode, you tap the current phrase to reveal the next one. Each tap adds your chosen number of seconds to your earned-time bank.

If you need more active friction, set a text note or voice rep before a tap earns time. You can also record your own phrase audio and play it during tapping or Timer mode.

## Earn, spend, and re-lock

When your bank has enough earned time, you can spend a completed 10-minute block on selected apps. The pass ends automatically, and the apps re-lock.

You keep the app installed and available when you need it. Access closes again when the pass ends.

## Common questions

### Can Stackwall block TikTok and Instagram?

Yes. You choose the apps and categories to block with Screen Time, including TikTok and Instagram when they are on your device.

### What happens when I need to use a blocked app?

You can earn time, choose a temporary unlock pass, and use the app until the pass ends. Stackwall then re-locks the selected apps automatically.
