About this app

Acellus is a personalized, video-based K-12 learning program used by over one million students across every U.S. state. Whether your student is in school, homeschooling, or learning virtually, Acellus meets them exactly where they are.

Every student learns differently. Short video lessons introduce each concept, followed by practice problems that adapt to how your student is progressing — a dynamic learning experience built around the individual, not the classroom average.

Learn at Their Own Pace
Students work independently through concepts, with personalized instruction that helps them truly master each one before moving on. No one gets left behind, and no one is held back.

A Complete K-12 Curriculum
Acellus covers all core subjects — math, reading and language arts, science, and social studies — plus Advanced Placement (AP), Exceptional Education, Career & Technical Education, and exam preparation. With over 470 courses, students from kindergarten through 12th grade follow a full, standards-based path.

Stay in the Loop
Monitor your student's progress in real time from any device. Scores, hours worked, and course progress are automatically compiled into printable reports — giving parents and teachers a clear view of how learning is going.

Always Improving
Student responses are continuously analyzed and used to refine course content, so courses get more effective over time. Lessons are updated daily.

Learning That Goes Anywhere
At school, at home, or on the go — Acellus picks up exactly where your student left off, on any device with an internet connection.

A Trusted Online Learning System

Before the update it was great. You could be on your computer desktop or laptop. After the update you cannot do anything that's helpful.No longer are you able to use a computer or laptop, only an app!! Not able to do the work properly. For example: scrolling up to reread or look for something. You get refreshed or signed out. Getting logged out while doing school work spontaneously. No longer are you staying logged in or saved ID/ password. you have 3 screens to go through in order to log in.

The app worked so much better before the update. Now to log into the parent account, I have to enter an eight digit pin as opposed to a four digit one and the numeral keyboard is gone, so I have to use my regular keypad, which just makes the extra digits even more inconvenient to input. I also can't scroll up about half the time I use the app. I can scroll down the page just fine, but not up. I then have to back out of the student or class I'm looking at, or reset the app entirely. Please fix.

We've used this app for years. It used to be great. Last several months there's been a LOT of issues. App glitching, video errors and not playing, and it doesn't stay signed in. But tell uts terrible. It's making me create a student sign in every single time the app opens. Then it's 50/50 if the app will actually open after having creating the student sign in again for the 10th time in a few hours. About half the time is says failure to connect and won't do anything. We NEED it fixed asap!
