Verdict
The clearest difference is review sentiment: RC Circuit Pro at 100% against Electric PRO's 0%. RC Circuit Pro also leads on iOS requirement (9.0 vs 12.0). Electric PRO's advantage is rating (4.2 vs 1.0) and ratings volume (5 vs 1). On price, update cadence, 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
RC Circuit Pro costs $0.99 and Electric PRO $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Electric PRO holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: Electric PRO has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of RC Circuit Pro's written reviews are positive against 0% of Electric PRO's, so the app with the better star average is not the one people write more warmly about.
RC Circuit Pro ships an update every 4 months, Electric PRO every 5 months. The most recent releases landed on June 4, 2026 and September 10, 2026 respectively.
