# 四级听力 vs i学

The clearest difference is in-app purchases: 四级听力 at none against i学's 7. 四级听力 also leads on iOS requirement (12.0 vs 15.0). i学's advantage is update cadence (every 3 months vs every 20 months). On price, ads and device support there is nothing between them.

Both are free to download. i学 sells 7 one-off in-app purchases. 四级听力 asks for nothing beyond the download.

四级听力 ships an update every 20 months, i学 every 3 months. The most recent releases landed on June 1, 2026 and September 22, 2026 respectively.
