Verdict

The call

The clearest difference is price: Simurelay at Free against Electrical Engineering Pack's $4.99. Simurelay also leads on device support (4 vs 2) and iOS requirement (15.6 vs 17.6). Electrical Engineering Pack's advantage is rating (4.7 vs 3.9) and in-app purchases (none vs 3). On update cadence and ads there is nothing between them.
