Solve your child's thoughtless smartphone usage with app locks instead of nagging.
From preventing smartphone addiction to limiting usage time and managing screen time, Smart Time Guide solves it all.
An essential smartphone management app for children, students, and exam takers!

★ Key Features ★

Customized Time Limits by Day of the Week
Set daily screen time down to the minute according to weekday and weekend schedules. Once the time is exceeded, all apps except allowed ones are immediately blocked, preventing smartphone overdependence.

Individual App Lock Management
Select and limit time for highly addictive apps such as YouTube, games, and SNS. Set essential apps like phone and messages to "Always Allowed" for peace of mind in emergencies.

Various Lock Modes
Password and pattern locks are supported as standard. It also features a natural "Fake Error Window" lock mode so children don't get flustered.

Real-Time Usage Status & Floating Timer
Check which apps were used and for how long today at a glance with a graph. A floating timer on the screen displays the remaining time in real time, helping kids build self-regulation habits.

Powerful Uninstall & Bypass Protection
Utilizes device administrator privileges to strictly prevent children from arbitrarily deleting the app, changing settings, or bypassing restrictions.

SMS Remote Control
If you forget your password or lose your device, you can instantly lock it or reset the password remotely via SMS commands.
