User reviews

Acellus sucks

It does not give good information and the teachers suck a lot. They do not get very good privilege and information. They are very under knowledge and they do not understand when the kids do not do very well. They just send them right off to a video if they get under 70% and I think that I said them off they should get a chance because I think they do know what they’re doing because they are because Acellus is very bad

Sucks

This app is rigged and SHOUKD never be downloaded

Max amount of steps

this new cap on the amount of steps you can do in a week is genuinely irritated, i used to do 40 and now i can only do 17. I was going to be able to be done in october and now it’s january. I’ve seen many people upset at this no one can get work done when that amount is done in 2 days even with notes and test and then you have to wait a week for it to restart 🙄 Other than that the app is fine but this money grab stunt you’re pulling is irritating

Good acellus

Very good i got cellus bot it connects too sign in I don’t like it but possible

Greedy

I truly used to love Acellus, but now with the new updates it is truly just no worth it on my NEW laptop and Ipad it glitches and replays the video and sometimes makes me not be able to answer questions without logging out. And I am going to be going to a new homeschool app from how they added the new week limit I am officially behind in school because they add this limit when I was out of town and skipped some of my work I can’t even catch up in a month. Please fix your glitchy app but I will be moving to a new app.
