Verdict
The clearest difference is review sentiment: UniTuner Pro at 100% against Tuner's 52%. UniTuner Pro also leads on rating (5.0 vs 4.5) and update cadence (fortnightly vs every 14 months). Tuner's advantage is price (Free vs $7.99) and ratings volume (190 vs 1). On ads and in-app purchases there is nothing between them.
