Verdict
The clearest difference is rating: OhmPlug at 4.4 against SPAN Home's 3.6. OhmPlug also leads on ratings volume (943 vs 103) and device support (3 vs 1). SPAN Home's advantage is update cadence (fortnightly vs every 3 months). On price, review sentiment, ads and in-app purchases 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.
OhmPlug holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: OhmPlug has 943 ratings behind it against 103, so its average is the more settled of the two. Written reviews complicate that: 29% of SPAN Home's written reviews are positive against 21% of OhmPlug's, so the app with the better star average is not the one people write more warmly about.
SPAN Home ships an update fortnightly, OhmPlug every 3 months. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
