This one has better interface on Android. For example the width of the option tab fits the width of the phone screen. Mentioned by other reviewers, it spoofs others navigator values as well. But I did not find per-page setting on my Android.

Alternative "User-Agent Switcher and Manager" by RayLo provides more options on Android but its interface does not fit to phone as well as this one.
