Verdict
The clearest difference is rating: DNS Optimizer at 5.0 against DRMemory's 4.0. DNS Optimizer also leads on ads (none vs shown) and ratings volume (7 vs 1). DRMemory's advantage is review sentiment (53% vs 25%) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, in-app purchases 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. DRMemory sells 1 one-off in-app purchase and DNS Optimizer sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
DNS Optimizer holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: DNS Optimizer has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of DRMemory's written reviews are positive against 25% of DNS Optimizer's, so the app with the better star average is not the one people write more warmly about.
DRMemory ships an update fortnightly, DNS Optimizer every 11 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
