Verdict
The clearest difference is price: n at Free against UniTuner Pro's $7.99. n also leads on ratings volume (3.2K vs 1) and iOS requirement (11.0 vs 15.6). UniTuner Pro's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence and device support there is nothing between them.
