# e本棚 vs Book Memo

The clearest difference is ads: e本棚 at none against Book Memo's shown. e本棚 also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.0). Book Memo's advantage is update cadence (every 2 days vs every 2 months). On price and in-app purchases there is nothing between them.

Both are free to download. e本棚 sells 2 one-off in-app purchases and Book Memo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

e本棚 ships an update every 2 months, Book Memo every 2 days. The most recent releases landed on October 20, 2026 and October 4, 2026 respectively.
