# Resistor Tools vs Resistor

The clearest difference is rating: Resistor Tools at 5.0 against Resistor's 4.0. Resistor Tools also leads on ratings volume (10 vs 1) and review sentiment (75% vs 67%). Resistor's advantage is in-app purchases (none vs 1) and iOS requirement (10.0 vs 12.0). On price, ads and device support there is nothing between them.

Both are free to download. Resistor Tools sells 1 one-off in-app purchase. Resistor asks for nothing beyond the download.

Resistor Tools holds the better App Store score, 5.0 against 4.0.
