# ETS 토익기출 수험서 vs 해커스 ONE

The clearest difference is rating: 해커스 ONE at 3.5 against ETS 토익기출 수험서's 1.0. 해커스 ONE also leads on ratings volume (10 vs 1). ETS 토익기출 수험서's advantage is in-app purchases (none vs 4) and review sentiment (81% vs 63%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. 해커스 ONE sells 4 one-off in-app purchases. ETS 토익기출 수험서 asks for nothing beyond the download.

해커스 ONE holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: 해커스 ONE has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of ETS 토익기출 수험서's written reviews are positive against 63% of 해커스 ONE's, so the app with the better star average is not the one people write more warmly about.

ETS 토익기출 수험서 ships an update every 3 weeks, 해커스 ONE every 2 weeks. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
