Verdict
The clearest difference is price: ChronoChord at Free against SideBand's $2.99. ChronoChord also leads on update cadence (every 5 days vs every 22 months). SideBand's advantage is in-app purchases (none vs 1) and iOS requirement (15.0 vs 17.6). On ads and device support there is nothing between them.
