Verdict
The clearest difference is in-app purchases: iTendry at none against Pro Guitar Tuner's 5. iTendry also leads on rating (5.0 vs 4.7) and iOS requirement (13.6 vs 15.0). Pro Guitar Tuner's advantage is ratings volume (10K vs 1) and update cadence (monthly vs every 5 months). On price, ads and device support there is nothing between them.
