My main go to is Iris. I just find myself clicking the app on my Android. It's easy and clean. Intuitive.

When I come across someone speaking in another language I quickly switch to amethyst. Amethyst could easily be my main but I guess I just like the layout of Iris better for some reason.

Last couple days I've loved using Nostrgram. This is my desktop choice and I'm wondering how an app might feel.
