# Electrical Engineering vs B

The clearest difference is in-app purchases: B at none against Electrical Engineering's 8. B also leads on iOS requirement (13.0 vs 15.5). Electrical Engineering's advantage is device support. On price there is nothing between them.

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