Lack of a decent RSS client is one of the major things keeping me on an iPad over an e-ink tablet. I wish manufacturers like Remarkable would get serious about having software platforms.

I think I might have what you want.

I built a web-based RSS reader for the Kindle browser (but it should work on other e-ink devices too).

You can read feeds online or download them directly on your device.

Please try it and let me know what you think!
