Printable PDFs vs Mandarin-learning apps

Short answer: apps are good for daily gamified practice and listening; printable books are better for reading together, building a book habit, and keeping the child away from another screen. Most families need both — but not at the same time.

Where apps win

• Audio and pronunciation feedback
• Short daily streaks and gamified review
• Adaptive drilling of single characters

Where printable books win

• Shared attention with a parent — the strongest predictor of retention
• No screen, no notifications, no in-app purchases
• A complete story, with meaning and illustration, not a word drill
• You own the PDF permanently; no subscription

What Little NiHao is not

We do not have audio yet; the books are reading material, not a speaking course. If your priority is spoken Mandarin, pair the books with a tutor, a class or an audio app. If your priority is a reading habit and character recognition, the books do that well.

A sensible budget

Start with the free book, then one level bundle. Add an app for listening if the child asks for it. Do not buy a full curriculum before the child has finished three books.
