Verdict
The clearest difference is in-app purchases: LockBox at none against Electrical Engineering's 8. LockBox also leads on update cadence (every 10 days vs every 2 months). Electrical Engineering's advantage is device support (3 vs 1) and iOS requirement (15.5 vs 17.6). On price and ads there is nothing between them.
