This is a pure javascript, single page application which does not load any external scripts except the official Google APIs. The application does not contain any minified or obfuscated code, does not use any npm modules, frameworks etc. This is intentional.

Only tested with the latest versions of Chrome and Firefox on windows 10 and android(chrome only). See documentation for technical details.
