Chem Pro: Chemistry Tutor in Your Pocket

The videos are educational but fairly limited in knowledge. The videos have a lot of white noise in the background and the narrator does seem rather nasally at times. The app creator does seem to be trying to improve this app though so hopefully it will improve in the future. A voice actor could be hired to narrate the videos more professionally. More videos could be added; I don't mind paying more for such an improvement. Different questions could also be reviewed. If the changes are good enough, I'm sure others would be persuaded to pay as well. This app needs to be a notch above Khan Academy in order to be worth $5, since Khan Academy is free and available to all.

Heard from a friend that this app helped him a lot when he took chemistry. I took his advice and downloaded the app when I took gen chem. The app was very useful and I was able to learn the topics with ease. Did well on all 3 tests given in the class and eventually ended up with an A. I would recommend the app to all students who have to take chemistry.

I got the iPhone version, paid the in-app $5 for the content, then got the iPad version, and tried viewing the EXACT SAME CONTENT as I paid for on my iPhone... they want you to pay $10 MORE (double iPhone cost and $15 total for both devices) just to view on iPad! What a scam!!! Hack: get the iPhone version (if you buy at all) for the iPad and pay 1/3rd what you would pay for both devices. The app menu displays in portrait only but the lessons play in landscape. Don't get ripped off by Justin Weinberg, ceo and founder of this scam. Do they not realize that poor students are his target market?! Why charge twice and DOUBLE for the same content but viewable on iPad. Try the Khan Academy videos first. Sal and the other narrator for Khan Academy has a much better voice and SOME personality, as opposed to monotone, sleep inducing voice of the Chem Pro narrator. $15 for that? HA! You may know chemistry but ethics and business are not your strong suit, Justin.
