Send EPUB, PDF and Word files to your Kindle straight from the Files app, and enjoy KTool on iPhone Duo.
Send articles and newsletters to your Kindle, and read them away from the screens that tire your eyes.
KTool turns what you want to read on the web into a clean Kindle read: long articles, X articles and the newsletters you subscribe to. It arrives on your Kindle e-reader or in the Kindle app, ready to read offline.

KTool only processes what you send to it. When you share or paste an article, the app sends the page and its URL to the KTool service, which packages it for reading and delivers it to your Kindle. Newsletters sent to your KTool address are processed the same way.
