While I am busy with Android, my 47th iOS app Chemical Substances has been approved (after 10 days waiting for review). This is the collection of quizzes on 200 most basic chemical substances: both organic and inorganic. With the beginning of an academic year, I see the growing interest to my chemistry apps.
The English description of the game is the following:
Learn 200 chemical substances that are studied in introductory and advanced chemistry classes:
* systematic and trivial names
* structures and formulas
* organic, inorganic, and organometallic compounds
* two different quiz modes
* 100 easy and 100 difficult chemicals

Great app! It refreshed me of common names and different oxidation states. Really helpful
Thank you for your feedback. Have you downloaded the iOS or Android version?
I have downloaded the Android version. No problems encountered so far.
It’s great to hear that there are no problems or crashes so far. I just started to transfer my apps to Android.
Could you please rate this app on the Google Play store. It now has rating 2.5/5 and, though I as an author may be subjective, I think it’s little bit too low.
Yes I will. Though I don’t have a Google + account yet, I will make one later to rate your awesome app. I have also downloaded your other app Hydrocarbons and will download the amino acid app later. These apps will really evolve chemistry learning. I hope you will continue this.

I have downloaded the chemical substances. Now Im learning them but at the moment it isn’t necessary for my studies that I know jet all of them. Is it possible to make a personality test only with the substances which are for me necessary?

Hi Yaël!
No, the feature you described is not possible yet in our applications. But we plan to add such a customization of questions by users in future.
Best wishes,
Andrey
