Verdict
The clearest difference is price: Solfa at Free against Hearing PRO's $1.99. Solfa also leads on rating (4.6 vs 3.9) and update cadence (every 3 weeks vs every 32 months). Hearing PRO's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
