# Electrical Engineering vs MTR

The clearest difference is in-app purchases: MTR at none against Electrical Engineering's 8. MTR also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.5). On price 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. MTR asks for nothing beyond the download.
