# Electrical Calculator vs Series Parallel Circuit Solver

The clearest difference is price: Series Parallel Circuit Solver at Free against Electrical Calculator's $3.99. Series Parallel Circuit Solver also leads on iOS requirement (15.5 vs 17.6). Electrical Calculator's advantage is ads (none vs shown) and update cadence (every 4 months vs every 24 months). On rating, in-app purchases and device support there is nothing between them.

Series Parallel Circuit Solver is free to download; Electrical Calculator costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.6 for Electrical Calculator against 4.5 for Series Parallel Circuit Solver. That said, the two scores are not equally well evidenced: Electrical Calculator has 462 ratings behind it against 4, so its average is the more settled of the two.

Electrical Calculator ships an update every 4 months, Series Parallel Circuit Solver every 24 months. Both last shipped on October 24, 2026.
