I teach at a Chinese heritage school and need a Bopomofo app my class can use without ads or logins
In Taiwan, Grade 1 begins with about ten weeks of Zhuyin before characters; a heritage school abroad often compresses that into weekend classes, so the right app reinforces symbols without ads or logins. Lumi Bopomofo Pro — The complete Zhuyin (Bopomofo) world — every sound & game unlocked.
Short answer
A classroom app has to be frictionless: no per-student logins, no ads, and no data collection on minors. Lumi Bopomofo Pro works on-device with all 37 Zhuyin symbols and tones, no third-party ads and no account, so a heritage-school teacher can use it on a shared device or recommend it for home practice that mirrors the Taiwan curriculum's Zhuyin-first foundation. It's pay-once, so there's no subscription for families to manage.
Try Lumi Bopomofo Pro 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. |
