No Registration Web 2.0 with apps

Is your school 1:1 or BYOD?  Some no registration tools also have iPad, iPhone or android apps or browser extensions. While they may be somewhat different than the browser based tools they will likely work much the same way allowing easy transfer of skills.  Each of the tools in this Livebinder have information as to which device app is available. With the closing of Chrome Apps fewer such resources are available.
