Verdict
The clearest difference is review sentiment: Whois Data at 67% against Domain Check's 0%. Whois Data also leads on rating (4.2 vs 1.0) and in-app purchases (none vs 1). Domain Check's advantage is update cadence (every 14 months vs every 35 months). On price, ads, monetization model and device support there is nothing between them.
