Traditional screens are fantastic everywhere but outside, especially on a sunny day. E-ink screens work well, but e-readers like the Kindle are difficult to type on and don't support external keyboards. SolarWriter gives you the best of both worlds. SolarWriter runs on your iOS device and acts as a hub between your keyboard and your e-reader. You type on the keyboard, and the text appears on both on the iOS device and on the e-reader's screen (via its web browser). Take advantage of your Kindle's (or other e-reader's) e-ink screen to put your thoughts on paper even outside, with no need to transcribe later. Write at parks, on beaches, in backyards... anywhere you wanted to but couldn't. Save files on your device, or share through email, SMS, and more. Detailed instructions for setup are included inside the app.
