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).
