What is it

Iconosquare is a Facebook and Instagram management tool.

Why I like it

Iconosquare is great at managing Instagram and Facebook accoutns for brands, and for a lot of brands, those are the big two right now. The 14-day free trial is also pretty sweet, but what I like most is that the advanced tier is fairly reasonable at $59/mo. Usually I find these tools around $99+.
In terms of product features, Iconosquare does all the things you'd expect. Analytics, scheduling, etc. They do also allow you to schedule Instagram Stories, which is pretty new, and they provide a great visual calendar so you can see what posts are going out when.
Overall, I recommend Iconosquare for any brand that wants to invest in IG and FB but needs a tool to help them schedule their posts all in one place.

Why I dislike it

It's only for Instagram and Facebook so if you want to invest in other channels you'll need a different tool. And usually those other tools--like Buffer or Hootsuite--include Instagram and Facebook so you might consider using those instead of investing in Iconosquare and another tool.
