# 技承 vs 电工证

技承 and 电工证 are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 技承 sells 10 one-off in-app purchases and 电工证 sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

技承 ships an update every 6 months, 电工证 every 3 months. The most recent releases landed on October 24, 2026 and October 11, 2026 respectively.
