Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Electrical Calculator lite sells 2 one-off in-app purchases. CMC Swift asks for nothing beyond the download.
CMC Swift holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculator lite has 574 ratings behind it against 1, so its average is the more settled of the two.
Electrical Calculator lite ships an update every 5 weeks, CMC Swift every 4 months. The most recent releases landed on September 18, 2026 and July 5, 2026 respectively.
