InterChem

	This app is a very useful app when doing calculations and removes the need to search up molecular masses and add up each molecular mass individually, the user just inputs the chemical formula, and the total molecular mass is displayed to as many decimal places needed for each atom.

User Interface 1.0/1.0 This app is very clean and modern with very simple user functions. All elements are colour coded depending on which group they’re in and are sorted into period order. The app allows the user to change the font from 3 styles. The app also allows the user to click on the element which will direct the user to a google page with a search result of the element, it can be seen as a bit naff, but useful nonetheless. This function is also paired with a setting to change your default browser. This app is optimised for iOS. 

 

In app Purchases: No 1.0/1.0

 

Accuracy: 0.75/1.0 This app allows the user to input invalid compounds for instance instead of HNO2 you can input values such as HNO18 which is obviously wrong, this is only a minor fault as the person using the app should really be at the level to which they should know if their chemical formula is wrong. This app is just a mere molecular weight calculator and will allow the user to input any values they desire. The developer could have changed this by paying attention to bond orders and the valency of each atom. 

 

Scope:  0.75/1.0 A useful tool for an undergraduate chemist or anyone at any level of chemistry. This app allows for a quick and easy calculation of MW, something from experience is cumbersome and takes up more time than it should, searching up and using your calculator, this app is convenient to the user but is not a necessity by any means.
