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.

3. Acknowledgements: icons for buttons were downloaded from iconmonstr or were created with Font Awesome.

Thanks!

Review Times for Apps [FruitoMarathon: Day 3 – Peach]

The third fruit in fruHarvest is a peach. It’s also on the app’s icon. Today I’ll write about the review times for applications submitted to the App Store. It usually takes about a week before the status “Waiting for Review” changes to “In Review”. This website shows daily estimates: between 2.99 days on Aug. 9 and 8.45 days on Jan. 7 in this year. Let’s compare with waiting times of my apps:

Monster! What Color is It? Take a Quiz!
Version 1.0 – Submitted: Jun 7, 2013 – Reviewed: Jun 14 (7 days) – approved
Version 1.1 – Submitted: Aug 7, 2013 – Reviewed: Aug 12-13 (5-6 days) – approved

Creating iOS App Icons [FruitoMarathon: Day 2 – Plum]

Circles is a great puzzle. But I’d like to continue “FruitoMarathon” in honor of my another recent app fruHarvest. The second fruit there is a plum. And today I’d like to talk about app icons in iOS7.

The icons in iOS7 differs from icons in iOS6 in shape (see a comprehensive discussion here), in size and the absence of the gloss. Before I prepared only 7 icon files, now I need 13 files:

Fruitopedia [FruitoMarathon: Day 1 – Tomato]

Today I start a series of posts that I announced in the description of fruHarvest – one of my new games. I’m going to buy each fruit that I included to the game, take a picture of it, and then eat it, of course.

Besides pics of fruits, the reader will get a piece of a story or an advice about app development. Today I’d like to talk about the section of fruHarvest called “Fruitopedia”. It’s logical to start with it because it’s essentially a table of all fruits represented in the game in the order they appear after finishing levels. So one may consider it as a built-in achievement board. It also explains why Tomato is #1.

ChemTemplate – fruHarvest is almost ready

I don’t write to the blog, because I work on new apps and old apps are doing just fine without my reminds about their existence. After all, their download number is at least 2 orders of magnitude higher than the number of visits of this website. So what are major news?

fruHarvest is almost ready and I’ll be surprised if it’s not submitted for the revision this week (though I still have to update my OS X and Xcode). Today I plan to test it on an iPad and complete all levels. I’m in the 28th (of totally 46) now.

– A lot of work has been done on creating a template for future apps. It’s called ChemTemplate for now, because chemistry-related applications is the major direction I’m going to take in the next couple of weeks. The template is the first necessary step to my idea of “a thousand apps”. It incorporates the code for ads, IAPs, game center, and many other useful features.

– I had some doubts about the potential of chemistry apps on the App Store. But now I have a lot of doubts about any of my app. Let’s see how fruHarvest will start. If it’s on the par with Greek Letters, then I’ll focus on small and simple apps rather than on big games. Keeping this in mind, I started to revise the outline of asmolgam.com. Some pages can be still under construction. For example, I combined my CV with the contact form and changed the “Forgotten Games” page to “Chemistry Apps” page.

Useful Links Update

Today I updated my Useful Links post. Please check it now. There are 12 links now.

Today I’m working on sounds, music and fonts for fruHarvest. I’m also thinking about abandoning the idea of Forgotten Games page and change it to a page devoted to chemistry and chemical apps. I’ll wait until my first chemistry quiz is published and then I’ll make a decision.

Back to App Development

After a month-long journeys and travelings across the country, becoming a Utah resident (bye, Pittsburgh!), I’m back to developing games.

I have a strict plan for myself to submit three new apps by the end of September. They are fruHarvest, a quiz about alkanes (a certain class of chemicals), and Push and Match (the names are subject to changing and extending).

Yesterday, I optimized the graphics in fruHarvest for iPad (now all pics are in normal, hd, and ipadhd resolutions), did the introductory screen with a dragon-gardener, and worked on several other minor things like icons, launching screens, fonts, etc. Hope to finish it very soon.

Monster! is Ready for Sale


So my first update has been approved. I wrote about it in the previous post and now Version 1.1 called Monster! What Color is It? Take a Quiz! is ready for sale on the App Store. It’s exactly two months since the 1.0 was released on June 14. There are several points I’d like to emphasize:

From Amino Acids to Greek Letters (and even further…)

Search for the best chemistry-related words brought an interesting discovery. There are still a lot of words with a high user traffic and relatively few apps associated with them. I noticed it accidentally for several Greek letters and an idea of a quiz about Greek alphabet came into my mind.
