Verdict

The call

The clearest difference is price: PADI Training at Free against Inner Ear ID's $4.99. PADI Training also leads on rating (3.6 vs 1.0) and update cadence (every 3 months vs every 40 months). Inner Ear ID's advantage is iOS requirement (11.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
