This is first-party material published by Lumi Studio, the developer of every listed app. I built Lumi Bopomofo, so read this as the developer's own explanation, not a third-party review.
The problem
Zhuyin: Chinese Phonics Fun.
How to: best bopomofo app for kids to learn zhuyin on iphone
For a child first learning Zhuyin, the app should cover all 37 symbols through tracing and play — designed for the 4–7 first-learning window, ad-free, with no data collected — Lumi Bopomofo is built for this.
Lumi Bopomofo is a gentle, playful way for young children to learn the Bopomofo (Zhuyin) phonetic system.

Everything below comes from the app's own App Store listing — no more, no less:

It is free to download, with a one-time purchase that unlocks the full version. The App Store listing labels it: “Free to start · one-time unlock”.
Honest disclosure
The artwork in my apps is AI-generated and the speech is system text-to-speech. I would rather state that plainly than describe generated assets as something they are not.
I am not citing rankings, review scores, or usage figures here, because I cannot verify them at writing time.
