Verdict

The call

The clearest difference is in-app purchases: CMC Swift at none against Electrical Calculator lite's 2. CMC Swift also leads on ads (none vs shown) and rating (5.0 vs 4.6). Electrical Calculator lite's advantage is ratings volume (574 vs 1) and update cadence (every 5 weeks vs every 4 months). On price and device support there is nothing between them.
