Overall, pretty great

Slader is an extremely helpful app for people like me who are horrible at math. I think (as the title of this says) that it’s pretty great, but it could definitely use improvements. For one, most of the math problems don’t actually show the work needed to get to the next step. Second, most problems actually start on the second step, which, as I have mentioned before, is hard to figure out without the work. One thing I think they could add to this app is a tutoring thing to give an overall idea of the section. I, personally, would definitely benefit from this. Despite these issues, I think it’s an amazing app and would recommend it to others.

If I didn’t depend on this app to get through my calculus class, I would never use it. It drains battery like nothing else and completely overwhelms my phone with lag (iPhone 8). Sadly the website is so congested with ads that I can’t take screenshots of answers as easily (to escape to the peace of Photos), so I have to subsist on this awful app. It probably has something to do with Apple’s last update, but no other apps have had any issues as bad as this for me. The app also sends you to re-education camps about the wonderful benefits of mind-sharpening word search apps every 2-3 answers. It’s not worth the free answers unless the class is ungodly difficult and you have nowhere else to turn to. Caring in class is easier and won’t drive you insane when it’s 11:30 you have to finish an assignment by 11:59 but Slader won’t let you get from section 3.9 to 3.10 without doing the icky shuffle.

I love this app so much because since the start of quarantine online school has been extremely difficult for me and I love how you can find an explanation that goes why that would be the answer, simple and great to use, my only problem is the adds, sometimes when i go to check a problem the same thing would keep popping up but besides that this app is amazing for cheating and you can do this with literally any textbook, you can search ur question or (do what i did) take a picture of the back of the barcode which should be on the back of the textbook and then type ur page number. sometimes not all of the answers are here but it’s extremely helpful. thanks developers!
