Amazing app!

Genuinely helped me understand chemistry so much, notes and videos are detailed and are explained in a way that is easy for me to understand. Not only that, but all lessons are free. The best learning app there is!!

Loving it!!! ❤️

I’ve never taken a chemistry class in high school. Now I’m taking my first college chemistry class. Once I got to a lesson on moles, I knew I had to have extra learning to help. This app helps me so, so much! I love it!

I also watch Rob Lederer’s YouTube videos (which I’m thankful are also provided in the app— so perfect!). They’re really attention-grabbing. He’s so happy and makes chemistry both fun and exciting. 😊 I definitely recommend using this app and watching his videos if anyone else needs help with chemistry. He makes it so much more interesting and easier to understand.

God bless and have fun doing chemistry! :)

Exceptional Resource!

Having everything you need to do well in chemistry, all in one place, and always with you on the go, makes doing well in the class infinitely easier. Buying the full version might just be the best two dollars you’ll ever spend!

ChemGuy is the best teacher ever!

With his help I was able to not only learn a lot, but pass my chemistry courses with flying colours. Not only in high school, but in my undergraduate studies as well. I’d recommend his courses to anyone taking chemistry in first year university/ college (to build a fantastic foundation) or high school.
