Verdict
The clearest difference is in-app purchases: Data Leek at none against Deep Whois's 4. Data Leek also leads on rating (4.8 vs 4.5). Deep Whois's advantage is ratings volume (172 vs 12) and review sentiment (85% vs 75%). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Deep Whois sells 4 in-app purchases, starting at $1.99 per 7 days. Data Leek asks for nothing beyond the download.
Data Leek holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Deep Whois has 172 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 85% of Deep Whois's written reviews are positive against 75% of Data Leek's, so the app with the better star average is not the one people write more warmly about.
Deep Whois ships an update every 4 months, Data Leek every 3 months. Both last shipped on September 28, 2026.
