How to choose (one sentence)

• Just want to speak first: Either LINE or App.
• Manage plans, kids, students, bills: Use Web App.
• Child/Student Account: Web App required.

Recommended combination

1. Use Web App to complete Main Path (Test → Plan → Practice).
2. Use LINE to practice a few sentences in your daily spare time.
3. Return to the app when changing plans, allocating minutes, or viewing bills.

Note on production environment

• You may only see "Please open within LINE" when opening the LIFF link directly outside the LINE application (such as Safari/Chrome directly opening it). This is expected behavior.
• Pre-release/native development may retain demo entry and does not represent production experience. For details, see Open in LINE.

if…

• "Plan/Family" not found in LINE: This is expected, please open the Web App. See Web App and LINE.
• Member accounts cannot log in to LINE: Use the App instead. The account number is the account + password sent to you by your parents or teachers.
• The progress on both sides seems inconsistent: Please refer to the records in the app and confirm that you are logged in with the same account.
