Inorganic Acids v. 1.3 – All questions for Free

It is the third time I update Inorganic Acids and Polyatomic Ions. The major change is the possibility to open the third group of questions (“Honor”, “Difficult”) by giving 200 correct answers in other modes rather than by purchasing the IAP. In my new apps, I rarely close any content behind the pay-wall and I’m going to reduce the paid content in my earlier apps as well.

Several changes in design to bring this app to my current standards took place as well. However, there are no new languages (I mean Dutch): this is the most laborious of all my apps in terms of localization.

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

SI Unit Prefixes – Update to v 1.2

I consider SI Unit Prefixes the most underestimated of my apps. It is not a great quiz, but it’s ok quiz and it could and should do better. After I received a feedback from a user that its design requires deep revisions, I almost immediately prepared this update that includes the best features of my most recent apps.

German States

I continue my series about the regional geography. Today let’s welcome German States. In terms of revenue from my apps, Germany is the third country after the United States and Russia. And everyone has heard about Bavaria and Bremen.

The English description of the game is the following:

Learn all 16 States of Germany: Bavaria, Brandenburg, Berlin and all others.
* names
* maps
* capitals
* flags
* coats of arms

National Parks of US – Guess the Park Quiz

In summertime, the app about the US National Parks seems to be appropriate.

Concordia University Online Nebraska wrote a very positive review of this app: http://online.cune.edu/national-parks-app-review/ and I hope that you’ll enjoy it as well.

The English description of the game is the following:

Guess all 59 US National Parks either from its photo or from the map.
Yosemite, Grand Canyon, Yellowstone, and 56 more parks!
Demonstrate your knowledge of the American wilderness and prepare for the new adventures!

*****

It is one of America-centered apps, but my experience with 50 US States and US Presidents was positive. Some of photos in the app are my own, others are taken from the nps.gov website. It’s handy that every picture done by the US government employee is in public domain. This app makes me want to visit all those parks I haven’t seen yet. My count is 22/59 so far.
