There are some apps that, the more you use them, the more you love them - Fibery is one of those apps. This is perhaps one of the best-designed software apps I've ever used (in any category) - it's intuitive, extensible and complete. The folks who wrote this really put a lot of thought into the UX and architecture. Every time I turn around, I discover a new feature that enhances my workflow.

I wouldn't call this a "dislike" aspect, but Fibery has so many capabilities that it took me a while to fully ramp up. To be fair - it was usable right out the gate, and there's a fairly complete portfolio of templates, but I decided to roll my own, so I built my productivity-task manager from scratch. In hindsight, I would recommend using a template. Review collected by and hosted on G2.com.
