I’ve been working on an eReader remote for iOS for a while.

It doesn’t work with Kindle (sorry), but it’s been tested with Bluetooth-capable Kobo (@kobo) and Boox devices.
It’s free, and ad-free.

If you try it and like it please consider leaving a review!

I mostly use it to read in bed (see attached photos) 😅
