Short answer
There is no rule that a preschooler must learn Zhuyin first — Taiwan's early-years guidance favours play, stories and songs over formal drilling, and first-grade teachers do teach all 37 symbols from the start over roughly the first ten weeks. If your child is curious, a gentle, playful introduction (games, picture books with Zhuyin) can ease that start without pressure; if your child isn't interested, pushing can backfire and sour them on reading. Lumi Bopomofo fits the gentle route — it teaches the 37 symbols through play, pay once, no ads, with a parent gate — as light exposure, not a bootcamp.
Try Lumi Bopomofo on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
