About

Aim990

Aim990 is a diagnostic English coach for TOEIC Listening & Reading-style study. It is not a question dump: every session you open is prescribed by your own answer evidence. HOW AIM990 WORKS 1. 8-minute diagnosis — about 20 grammar, listening and reading tasks estimate your practice band and pinpoint your three weakest skills. 2. Personal prescription — those skills become a written plan: what to repair first, why it is costing you points, and how long it should take. 3. Focused practice — each day drills one prescribed skill in three phases: diagnose, repair, verify. No endless random sets. 4. Day 30 recheck — the same skills are measured again, so you can compare Day 1 evidence with Day 30 evidence and see what actually moved. INSIDE YOUR COACH - Evidence ledger that records accuracy and pace for every skill - Weakness radar with your top three repair targets - Grammar speed drills with 15-second clues - Reading time trainer for long passages - Listening dictation and shadowing with on-device speech - Spaced-repetition vocabulary with meanings in your language - Practice mock with an estimated practice band - Panic Mode for the final 1, 3, 7 or 14 days - Apple Watch companion for quick reviews PRIVATE AND OFFLINE No account, no login, no ads, no tracking. Your evidence ledger stays on your device and daily practice works offline. ONE-TIME PURCHASE Unlock everything with a single purchase. No subscription, no renewals. TOEIC is a registered trademark of ETS. Aim990 is not affiliated with, endorsed by, or approved by ETS. All practice tasks are original and unofficial, written for TOEIC Listening & Reading-style preparation. Aim990 does not use official test questions, and every band is an unofficial estimate, never a guaranteed score. Optimized for iPhone Duo.
