I prepared a major update for Famous Scientists. Perhaps, I spent more time on it than on the original app, but it’s worth it. The number of improvements is significant:
1) 20 new scientists (from Descartes to Avogadro) with info descriptions.
2) Main menu like in my other apps with the choice of modes.
3) Multiple-choice mode (called “Chaos”, while the original linear mode is called “Order”). Portraits of scientists can be answers and the buttons are scaled correspondingly.
4) There is no longer possible to lose and start all over after 5 wrong letters. This innovation didn’t stimulate purchasing of Unlimited Hints and just annoyed the players.
5) Minor corrections in the German title and keywords. However, I didn’t add the Dutch localization (though I added a new Dutch scientist – Antoine van Leeuwenhoek, an inventor of the microscope and the discoverer of unicellular organisms).
If these improvements revive the app, I’ll update several my old apps as well and I’m always open to your suggestions.
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.
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.
The second update for 50 US States adds a lot of new content – two new modes.
1. State flags
2. Challenge – a multiple-choice quiz on maps, capitals and flags of all 50 states.
Among smaller additions: Dutch localization and a link to the US Presidents app.
This time I added to European Countries those useful features that I have previously implemented in the update to 50 US States: 14 letters on the “keyboard” and scaling of the answer boxes to accommodate all those 14 letters.
Moreover, I added to European Countries a new mode called the “Time Game”. It is essentially the European Challenge mode with a timer. The goal is to give as many correct answers as possible during 1 minute. Each wrong answer cut the time by 5 sec. A similar mode was in my old app Greek Letters and Alphabet.
The second addition is the Dutch localization. Initially I thought to add it to Chemical Elements but European Countries suited better for attracting users from the Netherlands and Belgium.
50 US States was my the most successful app so far and has changed the focus of my app-making efforts from chemistry to geography. Now it gets the first update and there are three important improvements.
1. There is a new mode “Find the state on the US map”. It is somewhat similar to the previous mode with state borders outlines but it shows where exactly the state is situated on the US map. Most people will find this info quite important. For smaller states of the Northeast, I use the zoomed map. Still Rhode Island is a tiny red spot.
2. There are now 14 rather than 12 letters on the player’s “keyboard”. And the answer boxes are scaled down accordingly if the name is too long. So if the answer has 14 letters or less, you can spell it completely. If it has more than 14 letters, you can place first 14 and then there are additional letters printed with a large blue font. This is a very important improvement and now I wonder why I didn’t do it for my very first quiz of this type.
3. Despite high downloads and ad revenues for 50 States, nobody purchased an IAP “Remove Ads”. It is very surprising for me, because even in a very nerdy and unlocalized app about Heterocyclic Compounds, there was one ads-removing purchase. It seems that ads are fine for most of users. At the same time European Countries quiz has shown that people are willing to pay for an additional content. So in the new mode, I made only the first half of questions free. Then the player sees the “Buy screen” and is offered an opportunity to support the developer (i.e. me), get the rest of the questions and remove all ads: the banner and interstitials.
And as usual, there are tons of small fixes in design, localization and keywords. The new mode and main menu prompted me to change two of five app screenshots. This update is a huge step forward for this game and all my quizzes. Enjoy!
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!
The Greek Letters and Alphabet 2 was approved and released yesterday together with Carboxylic acids. Now I’d like to write briefly about the first one.
Many (7.5) months ago, I published my second app called Greek Letters and Alphabet. I didn’t expect much from it, but it turned out to be fine. Especially, after it accumulated 10+ positive ratings and I made it a paid app. When I thought about updating it, I had two options. But the normal update to v. 1.1 would hide the rating history and I planned more serious changes in the quiz modes that would require the complete rework of the main menu. So I decided to go with the second option and release Greek Letters and Alphabet 2.
The English description of the game is the following:
It is a perfect app to learn Greek letters and alphabet. Choose the way of studying that suits you the best:
* Quiz “Find the Letter”
* Quiz “Name the Letter”
* Greek alphabet table
* Example of the usage of Greek Letters in math and science
* Time modes, multiple-choice questions (in Greek Letters and Alphabet 1)
Alpha, beta, gamma, and go on!
– The app is localized to 8 languages (vs. 2 languages in the first part)
– I used the same color in its design, but there are no ornaments, dragons, and the stuff
icons for buttons were downloaded from iconmonstr or were created with Font Awesome.
