I'm writing this for people new to this App: this is the official ACM Interactions magazine ( not a free magazine, mind you) App, therefore, you need to sign in your ACM web account with either full ACM membership or SIGCHI membership ( the later one is cheaper and you also got a printed version mail to you bimonthly ) Now back to App itself, it is ok but lack of some digital reader option, which is the why I give it a 4 instead of 5 - lack of text adjustment option, so I can only read it with one (smaller) size with no way to change it. Other than that, it's a decent reader App, and comes with print and text-flow mode. Run fine on my Nexus 9 and 6P.
No preview I can't read anything. Yell me that I need a login before I install the app, and try to convince me to sign up through the app by showing something interesting...
