# Electronic Devices Quiz vs Circuit Simulator

The clearest difference is ads: Circuit Simulator at none against Electronic Devices Quiz's shown. Electronic Devices Quiz's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (12.0 vs 15.3).

Both are free to download. Electronic Devices Quiz sells 7 in-app purchases, starting at $4.99 per month and Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Electronic Devices Quiz ships an update every 3 weeks, Circuit Simulator every 2 months. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
