## What is Mechanisms?

Mechanisms is the first app for organic chemistry that allows you to practice and learn reaction mechanisms by moving and manipulating electrons! 90% of college students find Mechanisms to be beneficial to their studies ー don’t get left out of the equation!

See, touch, and practice how chemical reactions occur at the particulate level in an
intuitive way. As you work through each exercise, you will receive hints and feedback based on the moves you make - so you learn as you practice and apply concepts. Mechanisms also provides you with real-time assessment, giving you a measure of your performance and comprehension every step of the way.

### 5/5 — It won’t let me make an account!!!

*2025-06-18, version 1.22*

This is my first time downloading this app and I have read good things about it but it keeps giving me an error message whenever I try to make a new account so I can’t even do anything!

### 1/5 — This is so bad

*2025-02-25*

I can’t pull apart electrons without them recombining and there is only 4 things to do other than to learn how to play

### 1/5 — Wrong about certain things

*2025-02-23*

It’s a cool idea. Thought it would be fun, but if you want to learn just pirate a text book or something.

### 1/5 — L

*2025-01-12*

How do I play this game?

### 5/5 — It taught me what textbook could'nt

*2023-12-24, version 1.22*

I always had difficulty understanding mechanism and needed an interactive way of learning it. Now I feel more confident that ever! I wish I had this app earlier.

### 5/5 — Underrated application that every chemistry student should have

*2023-11-23, version 1.22*

I downloaded this app during the middle of my A levels and it has remained useful all the way up to second year undergraduate organic chemistry. I would recommend purchasing all the levels, it will supplement your organic chemistry learning. Most reaction mechanisms you learn will on paper will be available on the app. For £10 it really is a bargain. I just wish they made some more levels.

### 5/5 — This app is absolutely amazing

*2023-05-19*

WELL WORTH THE PRICE FOR FULL VERSION. I took organic chemistry 1 and 2 from a nationally recognized and feared professor in the US, and passed top of the class. I give a good amount of credit to this app in all honesty. The mechanics of the reactions are so perfectly designed to get the user to see how and why things happen in reactions. For example, the app forces you to show resonance stability in certain situations where it’s helpful to understand that the reaction ONLY occurs because of the resonance stability. I recommend turning off the hints/goals option once you get the hang of things to really test your intuitive orgo skills. If you put in the work and invest yourself fully into organic chemistry, this app will absolutely help you understand and visualize reactions better. I also recommend going back to reactions you’ve passed in this app and predicting products on paper before doing it on the app if you’re using it to study. I love how the app is broken into sections like pi systems and carboxylic acid reactions. These are common sections that lecture based courses are often broken into as well. 10/10 love this app and I love organic chemistry more because of it!!!

### 5/5 — Amazing app for those who are new to organic chemistry

*2022-12-06*

I find this app to cover all bases in terms of basic organic chem with puzzles instead of flash cards teaching reaction such as substitution, elimination and Pi systems while teaching important ideas like formal charge and acidity ( both bronsted lowery and Lewis ) 
Would definitely buy again

### 3/5 — Great design but where are the updates for paid users

*2022-09-11*

One of the best organic chemistry apps -maybe the best- and the look is so nice which is why I bought the full version, but now I have not received any updates that increased the content, lessons, or features.  Where are the promised updates that was included as a perk for buying the app?  I'll change my rating is I get new levels like the feature list mentioned as an added value for the paid version.

### 1/5 — No

*2021-11-12*

This app is the worst thing to ever exist.
