Ebook reading progress sync; Android and Kobo - SLRPNK

Does anyone know of a good way to sync ebook reading progress between an Android phone and a Kobo Clara HD?

I think Koreader has built in progress sync.

It does. I have 2 different e-readers I regularly use and it’s super simple.

It does, and it supports Linux and macOS too

Readest (readest.com) can also use KOReader sync and works on iOS, Windows, and on the web.
