The best way to learn chemistry on the iPhone and iPod touch.

Introducing Chem Pro, the chemistry tutor in your pocket and the only resource you will need to excel in AP Chemistry or General Chemistry. Chem Pro features an exclusive lesson library containing a total of 80 videos that cover the entire year of AP and General Chemistry. It also includes nine sets of flash cards for memorizing all the needed elements and polyatomic ions, as well as some essential tools - a periodic table, a molar mass calculator, a unit converter, and an equation sheet, allowing you to save an enormous amount of time doing homework problems. See what thousands of high school and college students around the world have been raving about. This life saving app is now available for the iPhone and iPod touch!

Lessons: Struggling in your current chemistry course? Perhaps you need to review some material for an upcoming exam? Chem Pro contains over 31 hours of lesson videos, which makes it the perfect companion to have after you step out of the classroom. These lessons are dedicated to teaching students how to solve problems, the most important skill to master in order to excel in chemistry. In the videos, students are shown problems that are solved stepwise at a slow and easy to follow pace. The lessons don't just cover one example problem per topic, they cover all the possible problem scenarios that you would encounter in your homework or in an exam. Every topic is covered, from calculating molar masses to drawing Lewis structures to equilibrium. The first 10 lessons are bundled with the app for free and if you wish to continue learning, you can purchase and download the next pack of topics. Lesson videos are downloaded and saved to your device so you don't have to stream anything on the go. In addition, lessons always resume right from where you left off, no matter how long it has been since you last watched. You can truly learn whenever and wherever you go.

Flash Cards: Chem Pro contains nine sets of flash cards specifically designed for what any student needs to memorize for a standard chemistry course. With these flash cards, you can easily memorize 42 basic elements, 42 common polyatomic ions, common acid names, chemical colors (specifically for the AP Exam), and the 13 VSEPR molecular geometries. Simply select what you would like to memorize from the list of flash cards to begin memorizing. Just tap on each flash card and it flips around to show you the answer. Swipe back and forth to go to the previous or next card. It's that simple! What's even better is that every time you go to a flash card set, it automatically shuffles the order of the cards so that you can quiz yourself to make sure you know the material. This great feature can save you hours of time making index cards to memorize tedious chemistry concepts.

Tools: Chem Pro contains four essential and time saving chemistry tools. Use the periodic table to quickly look up information on any element. The equation sheet contains all the needed chemical equations, laws, and constants that you will find throughout your course. With the molar mass calculator, simply scroll and tap the elements in your molecular formula to quickly determine molar masses. The most commonly used elements are conveniently placed at the front of the calculator and you can tap the same element multiple times to add more in your formula. The unit converter contains all the standard units for length, mass, volume, temperature, pressure, energy, and time. Type the number and the select the unit you want to convert from and you are automatically presented with a choice of conversions.

Chem Pro will not only teach you chemistry in a way you won't find in the classroom, but also provide you with several time saving tools you will love to use. Chem Pro will make your chemistry course a lot less painful and more enjoyable. Download and find out for yourself today!

Room for Improvement

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.

DON'T GET RIPPED OFF BY 101 Education!!! Read about their scam...

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.

I love the content but the only thing keeping me from rating this app a 5 star is that it's hard to scrub in video. I find my self going back during the video and it would be nice if you added a button to go back 20 or 30 seconds back or forward too. Then, I'll give it a ⭐️⭐️⭐️⭐️⭐️.
