 Not RecommendedPros: 

Clean Design, Reasonable Price

Cons: 

Sluggish, Not Robust, and Buggy

I don't want to sound harsh but I've tried this for a while, both the iOS and macOS app. They are fine, but not great. You'll face strange bugs every know and then, and the app starts to behave unstable as soon as you push it. I would not recommend it. A solid alternative would be DEVONthink.
