# Electrical Calculations vs 建工专家

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 ships an update every 2 weeks, 建工专家 weekly. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
