Instant, on-device
Usage Access detects the foreground app on the supervised device, so blocks apply the moment a blocked app opens — no cloud check on every launch.
App blocking
Block distracting apps during study time.
Games, short video, and social apps pause when a routine is active on the supervised Android device — while the tools that help with studying stay available.
Blocked and allowed lists
Choose exactly which apps are blocked during a routine and which stay available — learning tools, calling, and maps can remain open.
Requests, not workarounds
The supervised user can request temporary access from the block screen. You approve or deny from StudyLumen Parent, and the result shows right where they asked.
Works offline
Enforcement runs locally, so app blocking keeps working with no internet connection.
Signed rules
Every rule set is cryptographically signed and verified on the device before it applies. Stale or unsigned bundles are rejected.
Tamper-aware
If enforcement is disabled, permissions are revoked, or the device time is changed, the supervisor is alerted.
How app blocking works
How does StudyLumen block apps on Android?
StudyLumen Child uses Android's Usage Access permission to detect which app is in the foreground on the supervised device. When a blocked app opens during an active routine, a clear block screen appears. Media that is already playing is paused. Everything happens on the device itself.
Can some apps stay available during a block?
Yes. Each routine has an allowed list. A typical Homework Mode blocks games, short video, and social apps while keeping learning apps, the calculator, calling, and maps available.
What does the supervised user see?
A clear block screen — not a crash or a blank app. From there they can send an access request. The supervisor approves or denies it from StudyLumen Parent, and the answer appears on the same screen.
When does blocking apply?
Blocking follows the routines you schedule — Homework Mode, Bedtime Mode, Exam Focus, or Weekend Balance. Schedules apply automatically; see the setup guide for how routines are created.
