"If you read fast but didn't understand it, you failed." ReadingGym trains speed, comprehension, and focus together — not just eye movement. • Daily 3-minute sessions with characters-per-minute (CPM) and words-per-minute (WPM) tracking • 5 quiz types — main idea, title, summary, fact, inference — every question with an explanation • 5 reading modes: Pacer, Chunk, RSVP, No-Regression, Scan-and-Read • 5 eye-training drills: Chunk Flash, Peripheral Expansion, Accelerated Reading, No-Regression, Schulte Table • 200+ original English articles and 600+ comprehension quizzes across Economy, History, Science, Self-Improvement, and Liberal Arts • Final score = Speed × Comprehension × Focus — racing through hurts your score • Available in English, Korean, Japanese, and Chinese (native content in each) ReadingGym does not promise "10x speed reading in 3 days." Instead, it builds the daily habit of skimming fast, locking onto the core, and reading the parts that matter precisely. For students, professionals, and anyone who wants to read more and read better. All content is built in and works offline. No account, no ads, no trackers.

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 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.
