Verdict
The clearest difference is ads: 建工专家 at none against Electrical Calculations's shown. 建工专家 also leads on monetization model (free vs free with in-app purchases) and update cadence (weekly vs every 2 weeks). Electrical Calculations's advantage is review sentiment (87% vs 75%). On price, in-app purchases 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 Calculations sells 3 in-app purchases, starting at $3.99 per 3 months and 建工专家 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Electrical Calculations ships an update every 2 weeks, 建工专家 weekly. The most recent releases landed on October 24, 2026 and October 14, 2026 respectively.
