PolyDigits

PolyDigits — Master numbers in any language

Numbers are the fastest way to feel confident in a language: prices, times, addresses, quantities. PolyDigits trains exactly that — with active drills instead of passive studying.

Three ways to practice:
• Listen/Drill: Hear a number → type it → check instantly.
• Flash Mode: Reveal and listen when you’re ready.
• Math: Train mental math and automate number fluency along the way.

Why it works
• Authentic pronunciation: Uses your iPhone’s native text-to-speech voice.
• Focused & simple: No fluff — just training.
• Progress you can see: Track what you’ve done each day.
