# 外研U学（家庭版） vs 红逗号

外研U学（家庭版） and 红逗号 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. 外研U学（家庭版） sells 9 one-off in-app purchases and 红逗号 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

外研U学（家庭版） ships an update fortnightly, 红逗号 every 3 weeks. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
