OK design but very buggy – Mendeley (PDF Reader) Review

I use Mendeley for Desktop extensively in my work as a consulting biologist and have yet to find a mobile app that's stable. I tried using this on my iPhone 6 running iOS 10 and it crashed four times in 15 minutes while trying to add tags or syncing . I like the simple GUI but apparently it's not stable enough to use on a regular basis. Being able to annotate and sync PDFs remotely is an important part of my workflow (since I read most papers during my commute or at home away from my laptop) and until they figure out how to build an app that does this well, I'll be investigating other apps.
