# Circuitry vs Impedance Calculators

The clearest difference is rating: Impedance Calculators at 5.0 against Circuitry's 3.8. Circuitry's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

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

Impedance Calculators holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Circuitry has 157 ratings behind it against 13, so its average is the more settled of the two.

Circuitry ships an update every 4 months, Impedance Calculators every 21 months. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
