Verdict

The call

The clearest difference is ads: Physics Lab AR at none against Electronics Toolkit!'s shown. Physics Lab AR also leads on rating (4.7 vs 4.3) and review sentiment (48% vs 38%). Electronics Toolkit!'s advantage is iOS requirement (11.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
