Frequently asked questions

What should I do if recognition is inaccurate?

Use a clear, complete image. In “Step-by-step recognition”, check the orientation, region, rows, columns and color codes, then adjust the main grid area. Review the generated pattern and edit color codes manually when needed.

What should I do if cloud sync fails?

Check your network, signed-in account and membership benefits, then tap “Cloud” to sync manually. Keep the current device’s patterns and export an important pattern as a backup before uninstalling the app or clearing data.

Questions about my account, purchase or membership?

Describe the issue by email. For a purchase issue, include the purchase time, product name and an order screenshot with personal information hidden.
