Provinces of Turkey

I was asked to prepare an app about Provinces of Turkey. I agreed because it was an excellent opportunity to get a translation into Turkish that can be potentially used in my other apps and the Turkish app market is going to grow.

The English description of the game is the following:

Learn all 81 provinces of Turkey: from Istanbul and Ankara to Erzurum and Van.
There are 4 different quiz modes about:
* names of all Turkish provinces
* their location on the map of Turkey
* two-digit province numbers (license plate codes)

Become an expert in geography of Turkey!

This app is translated into Turkish language.

Now I am mostly doing updates for my previous apps. When Apple releases a new iOS, the review process is usually slow. This app has waited for review for 11 days. Meanwhile, the Google Play version was published:

Get it on Google Play

Acknowledgements:
I am grateful to Mert for his idea of this app and for his translation into Turkish. It is a quite difficult language, and I wouldn’t be able to translate the app myself using Google Translate.

Learn Numerals in 7 languages

You may find the Learn Numerals app useful because it’s not about chemistry. It’s about another thing where you have to learn by heart a lot of new words: numerals (numbers) in 7 major European languages.

The English description of the game is the following:

In this app, you’ll learn the names of numerals in 7 important languages. Please choose the learning method that suits you the best.

* Tables
* Flashcards
* Quizzes

– Spanish
– French
– German
– Italian
– Portuguese
– Russian
– English!

*****

1. The app got into an “overnight” review. Yesterday, 8 days after the submission, the status changed to “in review”, but it was not until this morning, it was finally reviewed and placed on the App Store (formally after 17.5 h in review).

2. New features:
– It’s my first app since Monster! that uses different languages as quiz modes.
– The game is localized to those 7 languages as well. I believe that the localization at the time of the release (rather than in an update) was a key to the relative success of Hydrocarbons.
– There are interstitial ads that appear randomly around the 15th question (or flashcard). I’m disappointed with the “Press button to watch ads – Get 30 hints” approach that generated some impression but very, very little money.

SI Unit Prefixes

The idea of an app about SI Unit Prefixes came to me several months ago. I registered it at the iTunes Connect in September. At last, it’s here for everyone to enjoy.

The English description:

How many meters are in 1 nanometer? How many vertices does Dodecahedron have? Is 1 Mebibyte bigger than 1 Megabyte?
This app will help you to answer these and many other questions about decimal, binary, and number prefixes. It has a complete list of prefixes approved for SI units.

Please check 5 Tables and 5 Quizzes:
* Decimal Multiple: kilo-, Mega-, Giga-, etc.
* Decimal Fractional: milli-, micro-, nano-, etc.
* Number Latin: uni-, bi-, ter-, quart-, quint-, etc.
* Number Greek: mono-, di-, tri-, tetra-, penta-, etc.
* Binary: kibi-, mebi-, gibi-, etc.

A quick reference and an easy way to learn this information essential for everyone studying math, computer science, physics, and chemistry.

1. This app was uploaded several hours after Heterocyclic Compounds, they got into the review simultaneously, and SI Prefixes were approved 7 minutes before Heterocycles.

2. New features:
– This is my first app in the category Reference. Actually, after analyzing how the main page for each category is filled on the App Store, I’m leaning towards publishing all my apps as Games. To get on the first page of Education or Reference Apps, your app has to be picked up by Apple editors. In case of Games, all new free games get into the “New Free” bar.
– Tables show all question / answer pairs. It’s not only convenient for users, but helped me to check all errors and typos quickly during the development.

Hydrocarbon Chemical Formula

Word World

My first chemistry app Hydrocarbon Formula has been approved and is on the App Store. I plan this to be a start of a series of apps based on the model “Letter Quiz” where the player sees a picture or a formula and has to build its name from the given letters. There will be both chemical and non-chemical quizzes.

The English description of the game is the following:

This application is essential for students learning the basics of organic chemistry, for teachers, graduate students and professionals checking their knowledge of the subject. There are more than 175 structural formulas: fun to guess – easy to remember. Hydrocarbons are the most fundamental class of organic compounds, so it is very important to know their chemical names.

Questions are logically divided into 6 topics covering all possible hydrocarbons. Begin with crucial structures such as methane CH4, benzene C6H6, and octane C8H18 and then proceed to advance topics learning about benzopyrene C20H12 and cubane C8H8. In each question, guess the name of the hydrocarbon or use the hints.

The compound database is prepared by a PhD chemist. 178 structures and names of:

* Alkanes
* Cycloalkanes
* Alkenes / Alkynes
* Dienes, and Polyenes
* Aromatic Hydrocarbons (Arenes)
* Polyaromatic Hydrocarbons (PAHs)

***

1. This app was twice rejected because of too-long name (the reviewer asked to move all those “dienes, polyenes” to keywords) and because of failed (?) in-app-purchase. According to the attached screenshot, the IAP did work. So I wrote a letter to the Resolution Center and the app was quickly approved without any additional comments on their side or actions on my side.

2. New features are:
– “Watch Ads” button showing an AdMob interstitial and giving the player 20 hints
– Send an email to the author (asmolgam@gmail.com) button in the app
– 40 hints are given for sharing the info about the app on Twitter or Facebook
– Localization to 5 languages besides English and Russian: German, French, Spanish, Italian, and Portuguese.
