The RC Calculators app is now available in the Amazon Appstore for Kindle Fire, other tablets, and phones at [link=http://www.amazon.com/gp/product/B008ZEI7TE/ref=mas_pm_rc_calculators]RC Calculators[/link].

Testing for the Amazon Appstore is rigorous, so you can feel confident that the app is well tested. It does not and cannot access any of your personal information on your phone or tablet. It uses no device permissions at all. A future version may use network access and SD card access if permitted.

I have the Gas & Oil Mixing calculator done and there will be an update soon. Updates are trivial and automatic (in Google Play) if you select that option.

The [link=http://www.RCCalculators.com]RCCalculators.com[/link] web site has been updated and there are screen shots from a Kindle Fire on there now.

I'm going to do a lap counter and I'm trying to figure out if I should make it capable of counting laps for more than one plane. With multi-touch, I could have four quadrants and on a 10" tablet I think it would be feasible for one or two people to count laps for up to four planes.

One of my goals is to create a matrix program that runs on iPads and Android tablets using the mono development system that allows programming for both environments using C# and .NET ... but I need your support. So please buy the app if you have an Android device and spread the word. I'm going to add a Donate page to the app web site for those who support the concepts and vision.

At work I created an Android app to send and receive TXT messages and to communicate with web services. So I can create apps that store data in the "cloud". It would be cool to have a matrix / race management system with a central database.
