1994~2026학년도 수능·평가원 비문학(독서) 기출 185지문 2,041문항, 전부 들어 있습니다. 한 지문을 1·2·3회독으로 세 번 훈련하고, 다시 볼 시점은 앱이 관리합니다. ■ 3회독 설계 · 1회독 — 문장을 끊어 읽으며 소재의 뼈대를 잡습니다 · 2회독 — 문단 구조와 논리 관계를 심화합니다 · 3회독 — 시간을 재고 실전처럼 풉니다 ■ 매일 3지문, 오늘의 카드 목표 시험일을 입력하면 남은 분량을 역산해 오늘 풀 지문을 골라 줍니다. 무엇을 풀지 고민하는 시간을 없앴습니다. ■ 복습 큐 (간격 반복) 틀린 문항은 잊을 때쯤 다시 올라옵니다. 정답 여부에 따라 3일·7일·14일 간격으로 재노출되고, 약점 유형(일치·세부이해·보기적용)이 누적 집계됩니다. ■ AI 고수 풀이 막힌 문항은 국어 고수가 지문 어느 문장을 근거로 어떻게 판단했는지 사고 과정을 보여 줍니다. ■ 학습 리마인더 정한 시각에 알림을 보내 흐름이 끊기지 않게 합니다. ■ 요금 유닛1(지문 10개)은 가입만 하면 무료로 체험할 수 있습니다. 전 코스는 200,000원 일시불이며 구독이나 추가 결제가 없습니다. 수능 국어 비문학, 3번 읽으면 읽힙니다.

Verdict

The call

The clearest difference is in-app purchases: 비수다 at none against ReadingGym's 1. 비수다 also leads on update cadence (every 2 days vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
