Chemical Substances

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

Steroids

After geography apps, I briefly return back to chemistry with Steroids. They were the subject of my undergraduate studies and I suspect that it will be the most difficult topics among all my apps.

The English description of the game is the following:

Steroids are an important class of natural products with various biological functions: hormones (estradiol, testosterone), vitamins (vitamin D3), lipids (cholesterol). This app is designed for chemistry, biochemistry, and pharmacy students. It provides you with a convenient tool to get acquainted with chemical formulas of the most important natural and synthetic steroids. Many of them are top-selling drugs used for a treatment of asthma, baldness, prostate cancer, and as oral contraceptives.

* 40 steroid structures
* flashcards
* a multiple-choice quiz
* a spell-the-name quiz

Functional Groups

Functional Groups had to be my first organic chemistry app. The topic is so general and fundamental for everyone studying organic chemistry. However, it is published only now after several apps devoted to specific classes of compounds: Hydrocarbons, Carboxylic acids, Heterocyclic Compounds, and Amino Acids.

The English description of the app is the following:

The most important app for organic chemistry students includes 80 functional groups, the classes of organic compounds (hydrocarbons, ethers, esters, etc.) and natural products (amino acids, carbohydrates, lipids, etc.). Take a quiz or use flashcards for memorizing them. Start from the basic groups and proceed to the advanced topics.

*****

The app has four sets of questions and a flashcard mode. The mode called “Difficult” should actually be quite easy for a college student majoring in organic chemistry, not saying about PhD organic chemists. I included only 80 classes of organic compounds and natural products and I can easily propose 80 more important classes. It means that I have a lot of opportunities for the updates and all suggestions and comments are always welcome.

Amino Acids v. 1.2

For quite a long time, I didn’t like the app icon of Amino Acids Structures and Names. It was too dark and the spacial formula was hard to comprehend that it is cysteine. So I decided to prepare this update with a new app icon (proline has three-letter abbreviation Pro) and some other improvements in design and localization. I can’t say that I’m completely satisfied with the resulting icon. The formula could be a bit larger, especially its labels. Maybe I’ll update Amino Acids again, but not now.

Inorganic Acids v. 1.2 – Minor Corrections

I was not very careful sending the previous update of Inorganic Acids and Polyatomic Ions. Now everything is fixed and the app looks and works exactly as I wanted. Enjoy!

Carboxylic acid – Ester and Salt Names – Organic Chemistry Quiz

The app Carboxylic acids was released on Monday together with Greek Letters and Alphabet 2 and it was featured as a new free app in the Games/Word category for a couple of days. I got 250 downloads yesterday that is very good for so specific topic. Well, if people in Apple like “smart” apps, I’m ready to create many apps about different chemistry topics. We’ll see.

The English description of the app is the following:

Carboxylic acids and esters are one of the most important classes of organic compounds. They are everywhere:
* in food (citric acid; vinegar = a solution of acetic acid);
* in drugs (aspirin = acetylsalicylic acid);
* in fats (triglycerides are esters of fatty acids and glycerol);
* in plastics (polyesters);
* in biochemistry (transformation of pyruvate through the citric acid cycle);
* and even in ants 🙂 (formic acid)

Learn structures and trivial names of 50 most important carboxylic acids and their esters and salts.
* Aliphatic saturated acids
* Unsaturated and substituted acids
* Di- and tricarboxylic acids
* Aromatic acids

* pKa values of all acids!

*****

All modes are available for free (though all flashcards require in-app-purchase), but one has to give a certain number of correct answer in first modes to open the next ones.

Inorganic Acids v. 1.1 – an Update with Localizations

Today the Apple review team decided to eliminate the backlog of apps awaiting for the review and they approved my 3 apps and this update of Inorganic Acids and Polyatomic Ions. I submitted it just 14 hours before its status became “In Review”.

There are two major things:

1) Localization into Italian, German, French, Spanish, Portuguese, and Swedish languages. It’s probably the hardest of my apps to localize because the database is vast, strings are messy, and many compounds are quite obscure, so it’s impossible to find everything quickly in Wikipedia. But I designed the first version keeping only English and Russian in mind, and I don’t want to remove any compounds now.

As for the Italian translation, I am obliged to Sandro Soldano who did a great job on translating a lot of compounds’ names and fixing my lame Italian translations that I had done before. Thanks!

2) In v. 1.0, only the simplest acids and ions (“Acids 101”) were available without buying the in-app-purchase. This is less than one third of all compounds and since the purchasing activity was quite low, I decided to make the next level (“Acids 201” – 30 more acids and 30 more ions/salts) free. However, it is required to give 100 correct answers in the first level to get a free access to this second level. The IAP opens both the 2nd and 3rd levels immediately as it did before.

When I downloaded the app today, I noticed that I forgot to add one picture (more precisely, I added it but it has a wrong name: a little hyphen is missing). So it’s likely that I will soon submit Inorganic Acids v. 1.2 with “minor bugs fixed” in the What’s New section.

About three other apps that have been approved today, I’ll write in my blog later.

Chemical Elements of the Periodic Table – Name Quiz and Flashcards

The most popular chemistry-related topics are Chemical Elements and Periodic Table. There are more than 150 app about the latter on the App Store. I’m adding one more. But it’s not just a periodic table or a multiple choice quiz. It’s a cooler “spell the name of the element” quiz + flashcards + Mendeleev. Let’s see how competitive my app will be.

The English description of the game is the following:

You’ll learn the names of all 118 chemical elements with this app. Please choose the way of studying that suits you the best:

* Basic Elements Quiz
* Flashcards
* Periodic Table
* Advanced Elements Quiz

Please check the short bio of Dmitri Mendeleev, the discoverer of the Periodic Law.


*****

– The game is available in 8 languages. It’s very easy to find translation of elements’ names.
– The buttons in the main menu look like “element cards”. For the first time, I added a link to my another app (Hydrocarbons) in the main menu.
– Periodic Table is very neat. One can find all 118 elements, their atomic numbers and masses.

For the app icon a fragment of Ilya Repin’s Portrait of Dmitry Ivanovich Mendeleev wearing the Edinburgh University professor robe (1885; The State Tretyakov Gallery, Moscow) is used.

Thanks!

Amino Acids v. 1.1

A new version of Amino Acids Structures and Names was approved on Monday, simultaneously with the Inorganic acids app. That’s why I decided to write about the new app first.

There are several improvements and changes. I added the Main Menu, so now the user can choose between 5 modes: 1) names of 22 proteinogenic amino acids; 2) their abbreviations; 3) 22 flashcards on them; 4) other related compounds, such as dipeptides and non-proteinogenic amino acids; 5) 19 flashcards about these other compounds.

I added German, French, Spanish, Portuguese, and Italian localizations. Translating the app into these languages proved to be beneficial for the Hydrocarbons app.
