Keeping track of what you have finished reading

Hello,

I'm new to the forum, have been using Calibre for a couple of months now. I use the Moon Reader + app on my android tablet and have just added in Calibre Companion. I love them all, thanks to those of you that created these tools!

My question - and maybe I am missing something in one of these tools - is how to keep track of what you have finished reading. I have a custom field in Calibre (yes/no) where I record what I've finished reading. I use that tag to keep anything already read from appearing in my content server.

The piece that I'm missing is how to keep track of what I finish on my tablet and remember to update my Calibre data later when back at my PC. I know I can send myself an email or something similar to that. I have used Moon Reader to "Add to Home Screen" as an easy reminder.

Are there any better ways out there?

Thanks,

Kathy
