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).
