Names and Formulas
If you are studying General Chemistry this app is for you. It can help you review the names and formulas of the most common chemical compounds. You can train yourself in 7 compound families taken largely from Inorganic Chemistry and in 140 formulas distributed in groups of 20 and randomly chosen without repeating those already displayed. You can choose traditional or IUPAC names.
The score is built on groups of 10 names and will help you evaluate your progress. In case of error you can count on immediate help.
I used Open Source tools. The code is written in Kivy, a Python library for multi-touch applications (https://kivy.org). I used Avogadro to draw molecules, an advanced molecular editor (http://avogadro.cc/wiki/Main_Page). To build images my tool was Gimp (https://www.gimp.org). Two of them were taken from Openclipart (https://openclipart.org). In the action bar I put four Material Design icons (https://design.google.com/icons).
