Understanding spoken numbers in English is deceptively hard. Native speakers rattle off dates, times, phone numbers, and prices at full speed — and most English learning apps never practice this specific skill. That's where Numblr comes in.

Numblr is a dedicated English number listening trainer. You hear a number spoken in a real-world context — a date for an appointment, a price at checkout, a phone number in a voicemail — and type what you heard. The app tracks your mistakes so you can focus on exactly where you struggle.

With support for IELTS, TOEFL, CAE, and PTE exam formats, Numblr is built for test-takers who know that the listening section's number questions are easy points — if you've practiced. The free tier covers basic number tests, while Numblr Pro unlocks advanced exercises, exam mode, and conversation-based practice.
