How to Block Apps When Your Child Uses Your Phone

TL;DR

Study Mode is an on-demand toggle that blocks every app except the ones you allow — activate it before handing your phone to your child

PIN-protected so your child cannot disable it; auto-deactivates after 4 hours as a safety net

14 categories of harmful content stay blocked at all times, plus Safe Search on 5 engines — even when Study Mode is off

Unlike Digital Wellbeing or Screen Time, Study Mode restricts only your child's session, not yours

Why Can You Not Just Uninstall Apps Your Child Should Not Use?

You hand your child your phone for homework. Five minutes later, they are watching YouTube Shorts, scrolling Instagram Reels, or playing games. You take the phone back, they ask again in an hour, and the cycle repeats.

You cannot uninstall these apps because you use them yourself. You cannot set permanent restrictions because it is your phone. You need a way to temporarily block everything except what they need — and then restore your phone to normal when they are done.

How Does One-Tap Study Mode Work?

ParentalEdge's Study Mode lets you block all non-essential apps with a single tap before handing your phone to your child. On a shared device, Study Mode is an on-demand toggle — you activate it only when needed. Here is exactly how it works.

What Gets Blocked?

When Study Mode is active, every app on your phone is blocked except the ones you specifically allow. Your child sees a lock screen when they try to open anything not on the list.

What Can You Allow?

You choose which apps stay accessible. Common choices:

Homework apps: Google Classroom, Vedantu, Unacademy, BYJU'S, Khan Academy
Learning tools: Duolingo, Quizlet, Google Translate, Calculator
Research: Chrome or any browser (with Safe Search enforced across Google, Bing, DuckDuckGo, Yahoo, and Yandex)
Communication: Phone and Messages (so they can call you if needed)

How Do You Enable Study Mode?

Open ParentalEdge on your phone
Tap Study Mode
Enter your 4-digit PIN
Select the apps your child needs
Hand over the phone

That is it. Takes about 5 seconds.

How Do You Disable Study Mode?

Enter your PIN again. Your phone returns to normal instantly. All your apps work as before.

What If You Forget to Turn It Off?

Forgot to turn off Study Mode? It automatically deactivates after 4 hours. Your phone will not stay locked accidentally.

Why Not Just Use Screen Time or Digital Wellbeing?

Android's Digital Wellbeing and Apple's Screen Time let you set daily time limits on apps. But they have two problems for shared phones:

They restrict YOU too. If you set a 30-minute limit on YouTube, it applies to your usage as well.
They are always on. You cannot toggle restrictions on and off quickly when handing the phone to your child.

ParentalEdge's Study Mode is designed for exactly this scenario: temporary, on-demand restrictions that only apply when your child is using the phone.

What About Harmful Content When Study Mode Is Off?

Even when Study Mode is off, ParentalEdge blocks 14 categories of harmful content in the background — including adult content, violence, gambling, dating apps, hate speech, and proxy/bypass tools. Safe Search is enforced across 5 search engines (Google, Bing, DuckDuckGo, Yahoo, and Yandex), including in incognito mode. This protection runs at all times, regardless of whether Study Mode is active.

What Does This Look Like in Practice?

6:00 PM — Your daughter needs the phone for a science project.

You open ParentalEdge, tap Study Mode, enter PIN
Allow Google Classroom, Chrome, Calculator, and YouTube (educational)
Hand over the phone

6:45 PM — She finishes and returns the phone.

You enter your PIN to disable Study Mode
Your phone is back to normal

No arguments about "just five more minutes on Instagram." Instagram was never available to begin with.

Which Devices Does This Work On?

Study Mode with Shared Device profile is available on Android phones running Android 6.0 and above — including budget devices from Xiaomi, Realme, Samsung, and Oppo. Install ParentalEdge from the Google Play Store, select the Shared Device profile, and you are ready to go.

Frequently Asked Questions

Is Study Mode scheduled or on-demand?
On a shared device, Study Mode is on-demand — you toggle it manually each time. On a child's own device, Study Mode can be scheduled to activate automatically (e.g., during homework hours).

Can my child disable Study Mode?
No. Study Mode is PIN-protected. Only someone with the 4-digit PIN can disable it.

Does Study Mode affect my phone when it is off?
No. When Study Mode is off, your phone works completely normally. The only background activity is the always-on protection that blocks 14 harmful content categories and enforces Safe Search.

How much does ParentalEdge cost?
₹999/year with a free trial. No credit card required — UPI, cards, and net banking are all supported.
