■ App Usage Timer & Locker – Stay Focused, Limit Screen Time

Have you ever lost track of time while using an app or playing a game?

Are you worried that your child is spending too much time on their smartphone?

This app usage timer and lock tool helps you manage screen time, avoid overuse, and build healthier habits for adults and children alike.

◆ Main Features ◆

■ Set Timer & Lock Apps

- Set a usage timer for each app individually (max 24 hours).

- Once the set time limit is reached, the app is automatically locked.

- The timer controls how long an app can be used continuously.

- After the app is locked, it remains inaccessible for up to 24 hours.

Example:

Set the timer on a video app to 10 minutes and the waiting time to 30 minutes. After 10 minutes of usage, the app automatically locks and remains inaccessible for the next 30 minutes.

■ Daily Time Limits & Schedules

- You can set daily usage limits for each app or app group. Once the limit is reached, the app is locked for the rest of the day.

- You can restrict app usage to specific time periods (for example, from 9 p.m. to 6 a.m.).

- You can schedule app locks by day of the week and by hour to suit school or work routines.

- You can monitor app usage history for the past 24 hours, 7 days, or 30 days.

Example:

Group Twitter, Facebook, and Instagram under “SNS” and set a 1-hour daily usage limit. All three apps combined can only be used for 1 hour per day.

■ Safe & Secure for Children

- Lock settings with a password to prevent unauthorized changes.

- Enable uninstall protection to stop kids from deleting the app (device admin permission required).
