I'm Rob Lederer and I taught chemistry for 35 years. I've taught all high school levels of chemistry, including AP Chemistry and IB Chemistry, too! Since 2003, I have been known as Chemguy to the students outside of my classroom. My Chemguy YouTube videos have millions of views. The Chemguy App that I have personally built has distilled my teaching career into a course that completely covers high school chemistry, AP and IB material, and first year university chemistry. Everything is covered: The Periodic Table, Compounds and Reactions, Stoichiometry, Solutions, Gases, Atomic Theory, Chemical Bonding, Molecular Shapes, Energy, Electrochemistry, Chemical Equilibrium, Acids and Bases, Organic Chemistry, Chemical Kinetics, Thermodynamics, and Calculating Uncertainty Values. Phew! This is what you get in the Chemguy App: 1. Over 200 video lessons, where I teach all the chemistry principles, give detailed explanations, and problem-solve through all the calculations in every unit of study. 2. My entire classroom note package. All the material explained, with tables and diagrams and pictures. At the end of each lesson there are practice problems, over 1000 in all, to hone your chemistry skills. 3. Tests! I have made close to 100 interactive quizzes for all the lessons and summary unit exams, too! That's a total of over 1000 questions to practice! 4. Chemguy Messaging. After going through all of the above, is there still something that you need help with? Send me a text in the chat function of the app! Let's talk about it! So, watch the videos, read the notes, do the practice problems, have fun with the quizzes, and cap each unit off with the exam. And if something is bugging you, chemistry-wise, send me a message and let's chat about it!

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!! -- Dancer493, 2023-11-16 ### ***** "Wow what a great teacher!" Some people just make it easier…all the materials are so well put together. Am going to share it with everyone in my Chem1110 class! -- jalaludin, 2023-02-07 ### ***** "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! -- MattyB-doesn'trap, 2019-08-01 ### ***** "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. -- JD_YYC, 2019-07-30 ### ***** "Excellent resource for chemistry students" Great organization of topics in the notes packages. Chemguy videos included. Quizzes, practice tests. This is a great app. Well done, Chemguy! -- Deis Cube, 2019-07-30 ### ***** "Excellent!" From beginning to end, this is what students will need. It takes them through everything they will need to be successful. I will be recommending it to my students! -- Darwin's Beagle, 2019-07-26 ### ***** "Awesome App" This is perfect for students who want to prepare for their future in Chemistry. Excellent for exam prep! -- ChrisGlassHalfFull, 2019-07-25 [View all Chemguy reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Chemguy Available In - [Canada](https://apptail.io/app/chemguy-hBej/canada) - [United States](https://apptail.io/app/chemguy-hBej/united-states) - [Australia](https://apptail.io/app/chemguy-hBej/australia) - [Azerbaijan](https://apptail.io/app/chemguy-hBej/azerbaijan) - [Belgium](https://apptail.io/app/chemguy-hBej/belgium) - [Brazil](https://apptail.io/app/chemguy-hBej/brazil) - [Belarus](https://apptail.io/app/chemguy-hBej/belarus) - [Switzerland](https://apptail.io/app/chemguy-hBej/switzerland) - [Chile](https://apptail.io/app/chemguy-hBej/chile) - [Colombia](https://apptail.io/app/chemguy-hBej/colombia) - [Czechia](https://apptail.io/app/chemguy-hBej/czechia) - [Germany](https://apptail.io/app/chemguy-hBej/germany) - [Ecuador](https://apptail.io/app/chemguy-hBej/ecuador) - [Spain](https://apptail.io/app/chemguy-hBej/spain) - [United Kingdom](https://apptail.io/app/chemguy-hBej/united-kingdom) - [Hong Kong SAR China](https://apptail.io/app/chemguy-hBej/hong-kong) - [India](https://apptail.io/app/chemguy-hBej/india) - [United Arab Emirates](https://apptail.io/app/chemguy-hBej/united-arab-emirates) - [South Korea](https://apptail.io/app/chemguy-hBej/south-korea) - [Kuwait](https://apptail.io/app/chemguy-hBej/kuwait) - [Kazakhstan](https://apptail.io/app/chemguy-hBej/kazakhstan) - [Malta](https://apptail.io/app/chemguy-hBej/malta) - [Mexico](https://apptail.io/app/chemguy-hBej/mexico) - [Malaysia](https://apptail.io/app/chemguy-hBej/malaysia) - [Netherlands](https://apptail.io/app/chemguy-hBej/netherlands) - [Norway](https://apptail.io/app/chemguy-hBej/norway) - [Philippines](https://apptail.io/app/chemguy-hBej/philippines) - [Romania](https://apptail.io/app/chemguy-hBej/romania) - [Russia](https://apptail.io/app/chemguy-hBej/russia) - [Saudi Arabia](https://apptail.io/app/chemguy-hBej/saudi-arabia) - [Sweden](https://apptail.io/app/chemguy-hBej/sweden) - [Singapore](https://apptail.io/app/chemguy-hBej/singapore) - [Thailand](https://apptail.io/app/chemguy-hBej/thailand) - [Türkiye](https://apptail.io/app/chemguy-hBej/turkey) - [Taiwan](https://apptail.io/app/chemguy-hBej/taiwan) - [Italy](https://apptail.io/app/chemguy-hBej/italy) - [Argentina](https://apptail.io/app/chemguy-hBej/argentina) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
