# Electrical Engineering vs Resistor

The clearest difference is rating: Electrical Engineering at 4.9 against Resistor's 3.0. Electrical Engineering also leads on update cadence (every 2 months vs every 16 months) and review sentiment (74% vs 50%). Resistor's advantage is in-app purchases (none vs 7) and iOS requirement (13.0 vs 15.5). On price, ads and device support there is nothing between them.

Both are free to download. Electrical Engineering sells 7 in-app purchases, starting at $3.99 per month. Resistor asks for nothing beyond the download.

Electrical Engineering holds the better App Store score, 4.9 against 3.0. Both are backed by a comparable volume of ratings — 11 and 3 respectively. Written reviews point the same way: 74% of Electrical Engineering's written reviews are positive against 50% of Resistor's.

Electrical Engineering ships an update every 2 months, Resistor every 16 months. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
