# Impedance Calculators vs Circuit

The clearest difference is rating: Impedance Calculators at 5.0 against Circuit's 1.0. Impedance Calculators also leads on ratings volume (13 vs 2). Circuit's advantage is in-app purchases (none vs 1) and update cadence (every 5 weeks 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. Circuit asks for nothing beyond the download.

Impedance Calculators holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: Impedance Calculators has 13 ratings behind it against 2, so its average is the more settled of the two.

Impedance Calculators ships an update every 21 months, Circuit every 5 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
