Verdict
The clearest difference is price: NSLookup Z at Free against DnsChecker's $2.99. NSLookup Z also leads on update cadence (every 5 days vs every 8 months) and iOS requirement (16.0 vs 18.2). DnsChecker's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
