I have used OBDLink on Android, and it's ... not bad. There's some customizability in the interface (custom gauges & PIDs). But Torque Pro is definitely more manageable and customizable, not to mention compatible with a whole lot more OBD adapters.
For me it boils down to using Torque Pro or Forscan. The only thing I don't like about Forscan is the data intervals vary, usually not by much, but sometimes double or triple.
