Adaptive mock test + Part 1-7
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Take TOEIC once. Take it ready. A free 15-min diagnostic estimates your score, then AI predicts the exact day you'll hit your target — only when 85%+ confident.
Take TOEIC once. Take it ready.
ReadyDay is the first prep app that predicts the exact day you'll be ready to take the TOEIC® Listening & Reading test at your target score. Most apps tell you your current level. We tell you when to schedule the real test.
WHY ACCURACY MATTERS
The TOEIC fee in Japan is ¥7,810. A failed attempt costs the fee, the retake, and the deferred promotion or job transfer. We sell certainty: a conservative readiness signal, calibrated against real test outcomes.
HOW IT WORKS
1. A free 15-minute diagnostic estimates your current Listening + Reading ability separately, using 3-parameter Item Response Theory. No section can hide behind the other.
2. Daily adaptive practice serves items at maximum diagnostic value for your level, balanced across Parts 1–7.
3. A learning-curve model projects your trajectory toward your target. Monte Carlo simulation estimates the score distribution on your actual test date.
4. The app fires "ready" only when there's an 85%+ chance you'll exceed your target — and only after the prediction has been stable for 5 consecutive sessions. No noisy day-to-day score swings.
