## Most critical reviews (10 lowest-rated)

### 1/5 — Don’t use this

*2026-01-13*

Very unreliable app for test

### 1/5 — Worst app

*2025-12-12*

Struck between test. Screen freezes. Worst app ever seen . Plays with the students future. Never trust this app. Their call assistant also fools can’t give proper genuine reply.

### 1/5 — Bad quality photos for scan and upload

*2025-09-07*

Surprisingly this app take very bad quality photos in iphone 16 pro during scan and upload

### 1/5 — Pathetic Education App

*2025-08-29*

This app is highly unreliable and unprofessional. During my test, I was blocked without any genuine reason despite following all the rules. The monitoring system is poorly designed and creates unnecessary stress for students instead of ensuring fair exams. Such a flawed system is unacceptable for something as important as assessments.
Extremely disappointed with this app. It claims to provide a fair and smooth test environment, but in reality, it blocks genuine candidates without proper cause. The dual camera system is unstable, full of glitches, and wrongly flags normal activities as violations. This app needs serious improvements before being trusted for exams.

### 1/5 — App still loading - iPhone locked

*2025-07-13*

Even I was using my mobile and when I tried to upload the answers the App went in a loading mode where it locked my iPhone. It's being 3 hrs and it is still loading.
No luck contacting customer care.

I guess I have to wait till it drains all its battery.


Developers you should have taken care about it. Atleast there should be a timeout.

### 1/5 — This App Hijacked My Phone for hours

*2025-06-02*

This app didn’t just lock me out, it completely hijacked my phone like malware for hours. After finishing the exam, it refused to close, froze everything, and even disabled my ability to power off the phone. I watched my battery drain from over 60% to 0% like I was downloading call of duty! completely helpless, while the app sat on a lifeless loading screen.

I couldn’t message anyone, couldn’t make a call, couldn’t access anything, my personal device was held hostage for hours. No warning, no exit, no explanation. Just total control, even after I completed the test and almost submitted. 

Do you understand what it feels like to be locked out of your own phone in 2025? To be unable to call family, respond to work, or even shut the device down? It’s beyond frustrating, it’s violating.

This is not just bad app design, it’s irresponsible and invasive. No exam is worth this kind of control. If you care about your device, your time, or your sanity, do NOT use this app on mobile.

Mercer, fix this. You’re not just testing people, you’re ruining their day!!

### 1/5 — Very bad app for ipad

*2025-05-31*

It doesn’t work…give you no option to exit.

### 1/5 — Bad experience

*2025-05-23*

This doesn’t work on an iphone. This app totally hijacked my phone. Kept it on lockdown even when i was not doing any assessment. And i am still unable to use my control panel. My phone is still on lockdown even after i deleted the app. This is so scary.

### 1/5 — App still loading - iPhone locked

*2025-02-01*

I was using my mobile data and when I tried to upload the answers the App went in a loading mode where it locked my iPhone. It's being 4 hrs and it is still loading.
Not sure how my iPhone will work now. 
Someone says I have to wait till it drains all its battery. 

Developers you should have taken care about it. Atleast there should be a timeout.
