# RC Circuit Pro vs Vibroscope

The clearest difference is review sentiment: RC Circuit Pro at 100% against Vibroscope's 40%. RC Circuit Pro also leads on price ($0.99 vs $7.99) and device support (3 vs 1). Vibroscope's advantage is rating (5.0 vs 1.0). On ratings volume, update cadence, ads and in-app purchases there is nothing between them.

RC Circuit Pro costs $0.99 and Vibroscope $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Vibroscope holds the better App Store score, 5.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 100% of RC Circuit Pro's written reviews are positive against 40% of Vibroscope'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, Vibroscope every 8 months. The most recent releases landed on June 4, 2026 and September 4, 2026 respectively.
