# Impedance Calculators vs Electronic Circuits Calculator

The clearest difference is in-app purchases: Electronic Circuits Calculator at none against Impedance Calculators's 1. Electronic Circuits Calculator also leads on update cadence (every 2 months vs every 21 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Impedance Calculators sells 1 one-off in-app purchase. Electronic Circuits Calculator asks for nothing beyond the download.

Impedance Calculators ships an update every 21 months, Electronic Circuits Calculator every 2 months. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
