# Electric circuit calculator vs Resistor

The clearest difference is rating: Electric circuit calculator at 4.2 against Resistor's 3.0. Electric circuit calculator also leads on ads (none vs shown) and update cadence (every 4 months vs every 16 months). Resistor's advantage is in-app purchases (none vs 3) and review sentiment (50% vs 33%). On price and device support there is nothing between them.

Both are free to download. Electric circuit calculator sells 3 in-app purchases, starting at $3.99 per month. Resistor asks for nothing beyond the download.

Electric circuit calculator holds the better App Store score, 4.2 against 3.0. Both are backed by a comparable volume of ratings — 10 and 3 respectively. Written reviews complicate that: 33% of Electric circuit calculator's written reviews are positive against 50% of Resistor's, so the app with the better star average is not the one people write more warmly about.

Electric circuit calculator ships an update every 4 months, Resistor every 16 months. The most recent releases landed on September 23, 2026 and September 9, 2026 respectively.
