# Ohms Law Calc. vs Series Parallel Circuit Solver

The clearest difference is in-app purchases: Series Parallel Circuit Solver at none against Ohms Law Calc.'s 1. Series Parallel Circuit Solver also leads on iOS requirement (15.5 vs 17.6). Ohms Law Calc.'s advantage is update cadence (every 2 months vs every 24 months) and ratings volume (1.3K vs 4). On price, rating, ads and device support there is nothing between them.

Both are free to download. Ohms Law Calc. sells 1 one-off in-app purchase. Series Parallel Circuit Solver asks for nothing beyond the download.

Ohms Law Calc. holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Ohms Law Calc. has 1.3K ratings behind it against 4, so its average is the more settled of the two.

Ohms Law Calc. ships an update every 2 months, Series Parallel Circuit Solver every 24 months. Both last shipped on October 24, 2026.
