Verdict

The call

The clearest difference is price: ChordIQ at Free against Hearing PRO's $1.99. ChordIQ also leads on review sentiment (64% vs 21%) and rating (4.5 vs 3.9). Hearing PRO's advantage is in-app purchases (none vs 4) and iOS requirement (12.0 vs 15.0). On ads and device support there is nothing between them.
