Number Ninja
Dates, fractions, phone numbers — the numbers English learners always stumble on. Students race to say them correctly before the timer runs out.
Number Ninja draws from a deterministic number database across 10 difficulty tiers. No AI generation — every number is produced by precise static rules so teachers can trust accuracy 100% of the time.
Number Ninja is a number-pronunciation drill built entirely on a static database — no AI is involved and every number presented is guaranteed correct. Crucially, it covers the full spectrum of English number types: not just cardinals, but also ordinals, years, measures, fractions, currencies, and phone numbers — all the formats that appear in real-world English but are rarely drilled explicitly in class.
