# Deep Whois vs ERC Unlocker

The clearest difference is rating: Deep Whois at 4.5 against ERC Unlocker's 2.3. Deep Whois also leads on review sentiment (85% vs 56%) and ratings volume (172 vs 8). ERC Unlocker's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Deep Whois sells 4 in-app purchases, starting at $1.99 per 7 days and ERC Unlocker sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Deep Whois holds the better App Store score, 4.5 against 2.3. That said, the two scores are not equally well evidenced: Deep Whois has 172 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 85% of Deep Whois's written reviews are positive against 56% of ERC Unlocker's.

Deep Whois ships an update every 4 months, ERC Unlocker every 6 weeks. The most recent releases landed on October 23, 2026 and November 2, 2026 respectively.
