# i教育+ vs 交小星

i教育+ and 交小星 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. i教育+ sells 3 one-off in-app purchases and 交小星 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

i教育+ ships an update every 4 months, 交小星 every 3 months. The most recent releases landed on September 21, 2026 and August 24, 2026 respectively.
