CHEM 1100-General Chemistry II Podcasts
Since there is some course material overlap between CHEM 1090 and CHEM 1100, some podcasts will work for both courses. If you are viewing a podcast and you see “CHEM 1090" or “General Chemistry I" in the title, don’t panic! I’m using it for both courses.

Evaluated v5.32.0.2012212126 on an iPad Pro running iPadOS 14.3.
• Apple's Notes (7m13s, 12/24/2020)

• Evernote Scannable (6m35s, 4/9/2020)
Only has an iOS version. It connects with Evernote which is nice and it cleans up scans nicely. But, there's some hurry-up-and-wait and the app's control over the camera light is flakey. I don't recommend it. Evaluated on an iPad Pro running iPadOS 13.3.1.
