Verdict

The call

The clearest difference is rating: Device System Services at 4.5 against DRMemory's 4.0. Device System Services also leads on ratings volume (394 vs 1). DRMemory's advantage is update cadence (fortnightly vs every 4 months) and monetization model (ad-supported vs free with in-app purchases). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Device System Services holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Device System Services has 394 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 52% of Device System Services's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DRMemory ships an update fortnightly, Device System Services every 4 months. The most recent releases landed on October 5, 2026 and October 6, 2026 respectively.
