Verdict
The clearest difference is in-app purchases: True Tone Studio at none against Undertone Tuner's 2. True Tone Studio also leads on update cadence (every 4 days vs monthly). Undertone Tuner's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.5). On price and ads there is nothing between them.
