Terrible Experience with ERB – A Frustrating App with Awful Graphics and Horrible User Interface

I rarely leave reviews, but I felt compelled to share my experience with the ERB testing app, and it's not a positive one. First off, the **graphics** are downright dreadful. The interface looks like it was designed in the 90s, and not in a nostalgic, charming way. Everything feels outdated, low-res, and just plain ugly. The icons are clunky and hard to decipher, making even the simplest tasks feel like a struggle. It's honestly shocking that in 2024, an app like this could still look so bad. But the real problem is how **unintuitive** the app is. It’s supposed to help you prepare for tests, but navigating through it feels like trying to solve a puzzle with pieces that don’t fit. Buttons are poorly labeled, menus are confusing, and there's no clear flow to how you should use the app. I found myself clicking through random screens, trying to figure out where I was supposed to go next. There’s no tutorial or guide to help, and the entire layout feels disorganized. I spent more time trying to figure out how to use the app than actually preparing for my test. On top of that, it’s slow and laggy. I had several instances where it froze or crashed, forcing me to start over. This is a testing app—why should I have to deal with constant technical glitches? Overall, ERB is frustrating, difficult to navigate, and visually unpleasant. There are much better testing apps out there that offer smooth, user-friendly experiences with modern graphics. Avoid this one unless you want a headache.

Disappointed

The original ERB game in the franchise was a hit, so when I learned they were making a sequel I immediately got it. When I opened the game, I already was disappointed. Though they kept some of my favorite aspects of the original game such as the screen lock and timer, they degraded the levels(tests) and put quantity over quality. I hope they make a revival in the series, for this is a great disappointment.

This. Is. Terrible

This test was incredibly terrible. I wasted my entire month of may Slaving away on this stupid test. The app has bad graphics and don’t even get me started on the lag. This is the worst app that can ever exist. These games take longer than a game of monopoly with 10 dementia patients. My English teacher said something like, “Cassius’ Serpent’s tongue slithered into Brutus’ mind and corrupted his ideals” But all I know is that this ERB corrupted my sleep schedule. I swear that since May began my sleep hours went from a terrible 6 hours to ERB hours of 1. I literally will end the existence of standardized tests by making a chip that goes in people’s heads, JUST SO I NEVER HAVE TO TAKE THIS AGAIN.
