# Voltage Divider vs RC Circuit Pro

The clearest difference is review sentiment: RC Circuit Pro at 100% against Voltage Divider's 56%. RC Circuit Pro also leads on update cadence (every 4 months vs every 48 months) and price ($0.99 vs $1.99). Voltage Divider's advantage is rating (2.7 vs 1.0) and ratings volume (3 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Voltage Divider costs $1.99 and RC Circuit Pro $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Voltage Divider holds the better App Store score, 2.7 against 1.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 56% of Voltage Divider's written reviews are positive against 100% of RC Circuit Pro's, so the app with the better star average is not the one people write more warmly about.

Voltage Divider ships an update every 48 months, RC Circuit Pro every 4 months. The most recent releases landed on October 8, 2026 and October 10, 2026 respectively.
