To monitor performance for a target simply go to Programs -> Edit Program -> Targets.
You can either see the raw trial data from All Trials or only the Cold probes.
The cold probe is the first data recorded for the target on each session.
Each trial outcome is color-coded to display succesful trials in green and non-successful in red. You can see details about the trial (including levels of prompting if the program is set up to record that) by tapping a trial.
