HeiLock

A gentle boundary for app time

HeiLock helps you manage app time. When it is time to stop, a familiar photo or a favorite video is there to help you pause, gently.

When time is up, reminders can feel different

01

Do not let time slip away

Set a session limit for an app. When time is up, HeiLock locks it automatically, trading mindless scrolling for a more conscious pause.

02

Open apps only when the time is right

Choose when an app is available. Work, study, and rest can each have their own boundary.

03

Make reminders feel warmer

Choose a photo or video you love for the lock screen. When the limit takes effect, something familiar helps you stop for a moment.

Your lock screen and app status, clear at a glance

Customize and preview the photo or video that appears after an app is locked. Added apps, usage time, and lock status are brought together on the home screen for one-tap management.

Different moments, different limits

Use session limits for quick entertainment. Use schedules for work, study, bedtime, and the hours that need more structure.

HeiLock gives you several easy ways to shape app time around real life.

Set a session limit

When the selected time is reached, the app locks automatically, a gentle cue to pause.

Single-use limit editing screen

Set allowed hours

Use apps only within the windows you choose, so every part of the day has its place.

Allowed time window editing screen

When you pause, see something you love

The locked countdown screen can show the photo or video you choose. Keep one image, play one video, or let photos and videos cycle. HeiLock adjusts the text color to keep the timer clear, so the pause feels natural.
