# Electrical Engineering vs Energy Quiz

The clearest difference is in-app purchases: Energy Quiz at none against Electrical Engineering's 2. Energy Quiz also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.6). Electrical Engineering's advantage is update cadence (every 4 months vs every 20 months). On price and device support there is nothing between them.

Both are free to download. Electrical Engineering sells 2 one-off in-app purchases. Energy Quiz asks for nothing beyond the download.

Electrical Engineering ships an update every 4 months, Energy Quiz every 20 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
