It's a good app, with good teachers, but ever since the update; you can't use the web browser anymore! 😤 My brother has an Amazon tablet, and he can't use his tablet to get into class. He could've used the browser, but now it just shows a tutorial on how to get Acellus, WHICH YOU CAN'T EVEN DO. Despite this, it's still pretty good.

Absolutely love Acellus!! My child was struggling in public school, going as far as having teachers tell him he would never catch up with the others and calling him stupid. We switched to Acellus and that's been the best decision I've made! He has amazing grades now, and it makes it so much easier for him to understand. When stuck in a lesson and struggling, I love that it offers helpful videos before continuing. His entire attitude towards school has changed since switching.

Acellus is the best Schooling system I have experienced by a long shot. I can't recommend a better schooling system for children who have ADHD.

I hate it all it does is waste your time, and you can even any of the lessons without getting signed out

I send my children here and to be able to access the app every day without it crashing is unacceptable. There is a white screen on openind and if you do get in the app will just shut down. Last year it was worse my son couldn't to school for a week since the app wouldn't work. If you can't fix these please go back to the website on browser. I do not wish to waste my money on school program that has bugs.

As a parent, I need to log in, so I can pay the tuition. For whatever reason, I can't log in now. If my kids lose their work because of a tech issue that causes me to not be able to pay, im going to be pissed. PLEASE FIX THIS ISSUE ASAP.
