# 参考書de英語脳 vs HSpeakRec

The clearest difference is ads: 参考書de英語脳 at none against HSpeakRec's shown. 参考書de英語脳 also leads on device support (3 vs 1) and iOS requirement (13.6 vs 16.0). HSpeakRec's advantage is update cadence (every 2 weeks vs every 3 weeks). On price and in-app purchases there is nothing between them.

Both are free to download. 参考書de英語脳 sells 4 one-off in-app purchases and HSpeakRec sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

参考書de英語脳 ships an update every 3 weeks, HSpeakRec every 2 weeks. The most recent releases landed on September 15, 2026 and September 14, 2026 respectively.
