# Electrical Series Calculator vs SJ Resistor Calculator

The clearest difference is rating: SJ Resistor Calculator at 5.0 against Electrical Series Calculator's 4.5. SJ Resistor Calculator also leads on update cadence (every 2 weeks vs every 8 months). Electrical Series Calculator's advantage is in-app purchases (none vs 5) and ratings volume (13 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. SJ Resistor Calculator sells 5 one-off in-app purchases. Electrical Series Calculator asks for nothing beyond the download.

SJ Resistor Calculator holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Electrical Series Calculator has 13 ratings behind it against 1, so its average is the more settled of the two.

Electrical Series Calculator ships an update every 8 months, SJ Resistor Calculator every 2 weeks. Both last shipped on November 4, 2026.
