Verdict

The call

The clearest difference is rating: Electrical Engineering at 4.7 against Electronics Tools & Calculator's 4.0. Electrical Engineering also leads on review sentiment (33% vs 17%) and ratings volume (252 vs 16). Electronics Tools & Calculator's advantage is in-app purchases (none vs 2) and update cadence (every 2 months vs every 4 months). On price, ads and device support there is nothing between them.
