Private Bopomofo symbol contrast cards

Choose any two Zhuyin symbols you want your family to compare, then generate printable practice cards that ask your child to find, point to, or trace each one. This tool never claims the pair you pick is commonly confused, and it never scores, diagnoses, or profiles a child.

Build your printable contrast cards

Choose two different symbols, an activity mode, and how many cards to print. This page never asks for your child's name, age, school, photo, handwriting, voice, or any other personal detail.

What this tool does not do

This tool does not assess, score, grade, or diagnose a child, and it never claims that the two symbols you chose are commonly confused. It only turns your own selected pair into printable finding, pointing, and tracing prompts.

This is a free, independent web tool. It is not the Lumi Bopomofo app, and it is not a diagnostic tool or assessment of any kind.

How these cards are generated

Card generation is a fixed, deterministic layout created by this site, not an adaptive or AI-personalized activity.

  1. Pick any two of the 37 basic Bopomofo letters (ㄅ through ㄩ); the pair is only the one you selected, never a suggestion from this site.
  2. Choose visual cards to find and point to the target symbol, trace cards to trace the target and compare it with the other symbol, or mixed to alternate both activities.
  3. Set how many cards to generate, from 4 to 12; the target symbol alternates between your two chosen symbols on every card.
  4. Print the cards and practice offline; nothing about your practice session is sent anywhere or stored by this tool.
  5. For official stroke order, use Taiwan's Ministry of Education portal linked below instead of relying on any app or website animation.

Bopomofo symbol contrast card questions

Does this tool assess, score, or diagnose my child?

No. It only turns two symbols you choose into printable finding, pointing, and tracing prompts; it never scores, grades, or diagnoses anyone.

Does picking a pair mean those symbols are commonly confused?

No. This tool never makes that claim. It only uses whichever two symbols you personally selected.

Does this page collect my child's name, age, school, or any personal data?

No. It only accepts your two chosen symbols, an activity mode, and a card count; nothing is sent anywhere or stored.

Where can I check official Bopomofo stroke order?

Use Taiwan's Ministry of Education stroke-order portal linked on this page; this tool does not reproduce official stroke order itself.

Is this the Lumi Bopomofo app?

No. This is a free, independent web tool. Lumi Bopomofo is a separate, optional app you can check on the App Store.

Want an optional guided Bopomofo app?

Lumi Bopomofo is optional. Its current App Store listing describes an app designed for roughly ages 4–7 with four play modes — listening and choosing the symbol, finger tracing, tones, and initial+medial+final blending — 37 collectible Bopomofo friends, a free download with in-app purchases, no ads, no subscription, no signup, and progress stored on-device with a Chinese/English interface. Verify the current listing before deciding, since features can change. These printable cards work fully without the app.
