이번 버전에서 개선된 점 - 공부 종료를 누르면 확인 창이 떠요. 실수로 눌러도 세션이 바로 끝나지 않아요. - 전화나 시리로 멈췄던 집중 사운드가 통화가 끝나면 자동으로 다시 재생돼요. - 위젯의 순공시간이 더 빠르게 갱신돼요. - 소소한 버그를 고치고 안정성을 높였어요. 늘 순공야르를 사용해 주셔서 감사합니다.

Verdict
The clearest difference is in-app purchases: Posture Timer at none against PureStudy's 2. Posture Timer also leads on iOS requirement (15.0 vs 17.0). PureStudy's advantage is update cadence (every 3 days vs monthly). On price, ads and device support there is nothing between them.
