Verdict
The clearest difference is rating: System Controls at 2.9 against Surge Guard's 1.5. Surge Guard's advantage is update cadence (monthly vs every 3 months) and review sentiment (11% vs 0%). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
System Controls holds the better App Store score, 2.9 against 1.5. That said, the two scores are not equally well evidenced: Surge Guard has 73 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 0% of System Controls's written reviews are positive against 11% of Surge Guard's, so the app with the better star average is not the one people write more warmly about.
System Controls ships an update every 3 months, Surge Guard monthly. Both last shipped on October 13, 2026.
