This application makes use of SendToReader's API. DroidToReader requires that you have a SendToReader account (create one at http://www.sendtoreader.com).
With DroidToReader you can send any web page to your Amazon Kindle instantly. These pages are formatted properly to remove unnecessary content while leaving the important stuff intact.
Send long articles or articles that you want to read later to your reader, where you can comfortably read them on a screen that won't strain your eyes.
After installing, launch the app and enter your SendToReader username and password. You can check that they're correct by tapping the "Test credentials" menu option. To send pages, just tap on "DroidToReader" in your browser's "Share" menu.
