### 3/5 — 😍😊😌🙂😕🙁😩😫😤🥺

*2026-08-26, version 3.1.8*

*+* I love the new update but there isn’t a student blog anymore I loved that. That’s how I found the middle school art. 🖼️ And I also loved the library please add it back!*+* 📚 

P.S. I wrote this review 2 years ago still no library and no student blog (theres a Library just not the same the stuff is made by student this time it sucks!!!)*+*

### 2/5 — The new update sucks

*2026-08-19, version 3.1.8*

Before the update it was really good and i could actually go back and catch up on lessons i messed on the past day(s) now it wont let me- and for people that cant see or read properly because of sight problems or like me who has dyslexia i cant always read right, thats why Read Out Loud should be there always for you to have- and the AI??? Why use AI when it was fine before it?- it was way better before the update and Acellus should really go back to how they had it in like 2022

### 2/5 — They got money hungry.

*2026-08-19, version 3.1.8*

Originally I started using Acellus back in 2020. It was so convenient and I could finish a class in a month. Recently they added a feature where after a weeks worth of work you can’t work in that class until Sunday. I’m behind and now I cannot catch up. It also keeps removing steps so classes are becoming even longer. Genuinely it’s such an inconvenience and is SO frustrating. My sister has emailed about this and they completely ignored it. Change this feature Acellus!!!

### 1/5 — This app is bad

*2026-08-17, version 3.1.8*

Do not get this app if you pulled your children out of school and were behind this app will not let you catch up. It makes you feel stupid and it does not do a good job at keeping track of your schoolwork. I really hope the next program I do is much better.😠

### 1/5 — I hate Acellus

*2026-08-17, version 3.1.8*

It’s scammer scammers scaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaammmmmmmmmmmmmmmmmmmmmmmmmmmmmmmerrrrrrrrr

### 3/5 — Hate The New Update

*2026-08-14, version 3.1.8*

I’ve quite enjoyed this program and how it has been so far. However, the new step limit is horrible. You cannot choose the amounts of steps you want to do anymore and it is very frustrating. The ability to do forty steps per week in each class was an amazing thing that is now gone

### 3/5 — I like this but I am so mad

*2026-08-14, version 3.1.8*

I spend 20 minutes trying to get tomorrow’s work done too, I’ve done i dont even know how many steps and it still says i have to do work tomorrow.
Not happy😫

### 1/5 — no

*2026-08-06, version 3.1.8*

mo

### 2/5 — i liked it before the update

*2026-08-06, version 3.1.8*

The new update is horrible! I was on a trip for a couple of weeks and i wanted to catch up. After like 30/35 lessons it tells me i’ve done enough school. Like, i need to catch up, there should be a mode where you’re trying to catch up or something and you say how many days you missed. I also don’t like this as well: write a book should have chapter books/customizable pictures but not like where you put stickers i meant like a canva sort of thing, like where you create your own wallpaper and stickers.

### 2/5 — Horrible

*2026-08-01, version 3.1.8*

This app used to be amazing and I was getting through my classes quickly while still obtaining the knowledge and skills. But they keep changing things and making it harder for students to complete classes as they want at the speed they want.
