# RC Circuit vs Voltage Divider Calculator

The clearest difference is rating: RC Circuit at 4.8 against Voltage Divider Calculator's 3.3. RC Circuit also leads on iOS requirement (12.0 vs 17.6). Voltage Divider Calculator's advantage is in-app purchases (none vs 1). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. RC Circuit sells 1 one-off in-app purchase. Voltage Divider Calculator asks for nothing beyond the download.

RC Circuit holds the better App Store score, 4.8 against 3.3. Both are backed by a comparable volume of ratings — 5 and 3 respectively.

RC Circuit ships an update every 6 months, Voltage Divider Calculator every 11 months. The most recent releases landed on October 5, 2026 and October 25, 2026 respectively.
