# Quick Domain Check LITE vs ERC Unlocker

The clearest difference is rating: Quick Domain Check LITE at 3.0 against ERC Unlocker's 2.3. Quick Domain Check LITE also leads on iOS requirement (9.0 vs 15.6). ERC Unlocker's advantage is review sentiment (56% vs 28%) and update cadence (every 6 weeks vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quick Domain Check LITE sells 2 one-off in-app purchases and ERC Unlocker sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Quick Domain Check LITE holds the better App Store score, 3.0 against 2.3. Both are backed by a comparable volume of ratings — 2 and 8 respectively. Written reviews complicate that: 28% of Quick Domain Check LITE's written reviews are positive against 56% of ERC Unlocker's, so the app with the better star average is not the one people write more warmly about.

Quick Domain Check LITE ships an update every 4 months, ERC Unlocker every 6 weeks. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
