- It syncs across all my devices. No 3rd party storage like Dropbox required. In fact what I don't like is GoodReader asks for too broad an access to Dropbox/OneDrive if you try to set it up.
- Books is first party app so absolutely no tracking whatsoever. GoodReader had Facebook SDK and Google Analytics and was trying to contact a bunch of other trackers the last time I installed it.
It worked 99% of the time. But then every few weeks it would overwrite my newer-annotated version of a PDF with an older one, and I'd lose chapters' worth (in one case an entire books' worth) of highlights. It was infuriating.
It had to be some kind of iDrive sync bug. It seems insane that type of stuff passes QA, I can't even imagine.
That hurts, sorry to hear. iCloud drive supports files sync for files 50GB or less in size. Have you experienced sync issues with iCloud drive too? Or with Dropbox?
My hypothesis is that Books does something wonky with metadata for extra sync logic, like it depends on reading the last "last page read" record but then sometimes fails to write that, and then loses the pointer to the new version altogether. I can't be sure, but I can't think of any other explanation.
Longtime fan of Goodreader here. Sorry to hear that Goodreader is trying to contact trackers. How did you find out? Any suggestions how to prevent Goodreader to contact those trackers, eg pi-hole?
On my devices (iPhone / iPad) I also use Lockdown app which allows you to blacklist IP addresses and domain so once I can see what an app is up to using pi-hole, I manually add those domains to Lockdown so that even when I am out of the house the trackers are blocked.
