How can tear down the growing barriers to education using iphone?

Question

Recently, I have had a growing feeling that the avialability, meaningfulness, and ease of use of educational app on the iphone has gotten worse not better.  In fact it feels like there are a growing number of specific barriers to education using the iphone.  I would like to discuss  one specific "barrier" to education--avialability in your country's app store by using a specific example--Einstien Pedometer App.
Back in 2011, the Einstien pedometer App by Kami was all the rage. Even popular science a noneducation maganize noted this innovation-- http://www.popsci.com/technology/article/2011-04/new-ipod-app-calculates-how-spe cial-relativity-affects-your-daily-activities .  However, now you cannot get this app unless your are in china as you can see from the orginal link:
http://itunes.apple.com/us/app/einsteins-pedometer/id427443192?mt=8
So I ask you all for help in tear down this barrier and tearing down this wall...
How can we tear down this barrier of country availability?
Is there a way to contact the orginal company like Kami?
Is there  a way to change your country and install it?  Is this safe for students to do?
Should I contact tech support?
This app like other by Vogt and Kuhn are important ones to me that I have found unavialable in the United States.  Measuring Relativity not just calculating it is important for the iphone future, because phones are currently one of the few mainstream devices to have a guarunteed across the board GPS chip!  Thus, unlike the innovations of Vogt and Kuhn, the Einstien Pedometer is a physics application that is only available using ones smartphone.
This is my tech support submission, which better explains why I felt this was a barrier:
  What happened to the Einstien Pedometer App?
  Back in 2011 there was a famous Einstien's Pedometer App by Kami.  Recently as of February 2014, I found out that this app was unavailable on the App Store due to "unavailable in the United States".  The android already has a similar app called "Proper Time" by N. Thinsell.  I wanted to include this app as part of my physics smart phone laboratory series.  Specifically, I have worked painstakingly to develop a lab so that students could measure special relativity time dilation using their smart phones GPS chip.  (The lab is similar to the work of P Vogt and J Kuhn which is different from many of gimmick apps, which are only ebooks of text, not actual physics measuring devices.)  The current unavailability of this app is simply another barrier to using iphones for education.  This is why I am very disappointed right now.  Incorporating Android systems into physics high school curriculum is easy; however, I have tried many times to try to incorporate apple products into the physics curriculum to no avail.  It feels like with each successful year there are more and more barriers to using iphones for application-level understanding in physics education.

Dah Veed,
How?  No really how do I contact the app developer from a foreign country?
Going back to my example, so far I was able to figure out alot of things about the app developer of the Einstien Pedometer app--except there contact information.  Besides prehaps seeking apples supports help in contacting the developer, do you have any other suggestions?
Information that I know so far:
App: Einstein's pedometer
Developer's Name: Mitsuru kamiyama
Language: Japanese
AppStore Page: https://itunes.apple.com/us/artist/kami/id362020177?mt=8
Developers really old website: http://playoffline.ddo.jp/app/
P.S. While it didn't exactly solve the problem, your reply was very helpful, so I thank you for your reply.
