# Impedance Calculators vs Science Calc

The clearest difference is in-app purchases: Science Calc at none against Impedance Calculators's 1. Science Calc also leads on ads (none vs shown) and update cadence (every 5 days vs every 21 months). Impedance Calculators's advantage is ratings volume (13 vs 3). On price, rating, device support and iOS requirement there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for Impedance Calculators against 5.0 for Science Calc. Both are backed by a comparable volume of ratings — 13 and 3 respectively.

Impedance Calculators ships an update every 21 months, Science Calc every 5 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
