We've been using acellus for a few years now, and I have loved it. Up until last month, when they made it so my kids couldn't access through their internet browsers, they HAD to download this garbage app. It crashes, videos dont play, trouble with log in, and on their tablets, it won't even open. Then if you try it on a cell phone, the screen is so small you miss important helpful information. Absolutely would NOT recommend.👎

was better when it was on a browser. also, vectored instruction is terrible. it doesn't even help, it's just annoying. when i use this app on my chromebook, it immediately crashes and videos won't load on my tablet. i can only use it on my phone. the rest of the app is fine, but it's hard to type long paragraphs on such a small screen.

Please fix the app, it's been absolutely terrible since it moved to app only and not web based platform. I have 3 kids working on 3 different devices and all of them have issues. It's becoming not worth the cost for the amount of frustration with the app now. Please spend time fixing the app or move back to web based. App is terrible! I dont even want to give it a 1 star.
