I create mobile websites and Android apps, focusing mostly on references tools and other resources for radio hobbyists.

Mobile Websites

Similar to the content of many of the apps, but with a few differences: (1) able to used by IOS and Windows mobile devises, (2) requires internet access for all features (no off-line features), and (3) occasionally some differences in content, especially for mobile websites that do not meet the standards for the Google play store.
