# サイトラ！英文速読特訓 vs ディアトーク

サイトラ！英文速読特訓 and ディアトーク both sit at 5.0 stars, but that hides the real split: 100% of サイトラ！英文速読特訓's written reviews are positive against 36% of ディアトーク's. サイトラ！英文速読特訓 also leads on ratings volume (28 vs 1) and device support (3 vs 1). ディアトーク's advantage is update cadence (every 3 weeks vs every 3 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. サイトラ！英文速読特訓 sells 3 in-app purchases, starting at $7.99 per month and ディアトーク sells 2 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for サイトラ！英文速読特訓 against 5.0 for ディアトーク. That said, the two scores are not equally well evidenced: サイトラ！英文速読特訓 has 28 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 100% of サイトラ！英文速読特訓's written reviews are positive against 36% of ディアトーク's.
