Verdict
The clearest difference is in-app purchases: Okotone at none against Chords Finder's 1. Okotone also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.0). Chords Finder's advantage is update cadence (every 10 days vs every 16 months). On price and device support there is nothing between them.
