# Ampère Mobile vs Electrical Engineering

Ampère Mobile and Electrical Engineering both sit at 5.0 stars, but that hides the real split: 74% of Electrical Engineering's written reviews are positive against 25% of Ampère Mobile's. Electrical Engineering also leads on update cadence (every 2 months vs every 11 months) and ratings volume (11 vs 1). Ampère Mobile's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price, rating and device support there is nothing between them.
