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.

Completely free No ads. No locked features. If you want, you can buy me a coffee :) Private: no accounts, no data sharing (everything stays on-device).
