# Simple Circuit Builder vs Series Parallel Circuit Solver

The clearest difference is rating: Series Parallel Circuit Solver at 4.5 against Simple Circuit Builder's 4.0. Simple Circuit Builder's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 24 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Series Parallel Circuit Solver holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Simple Circuit Builder has 28 ratings behind it against 4, so its average is the more settled of the two.

Simple Circuit Builder ships an update every 3 weeks, Series Parallel Circuit Solver every 24 months. Both last shipped on October 24, 2026.
