# Circuitry vs Thevenin

The clearest difference is review sentiment: Thevenin at 100% against Circuitry's 51%. Thevenin also leads on update cadence (every 3 days vs every 4 months) and rating (4.3 vs 3.9). Circuitry's advantage is in-app purchases (none vs 2) and ratings volume (156 vs 11). On price and ads there is nothing between them.

Both are free to download. Thevenin sells 2 in-app purchases, starting at $4.99 per month. Circuitry asks for nothing beyond the download.

Thevenin holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Circuitry has 156 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 51% of Circuitry's written reviews are positive against 100% of Thevenin's.

Circuitry ships an update every 4 months, Thevenin every 3 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
