Frequently Asked Questions

Labels are shown in Japanese, even when the language is set to non-Japanese.

If your iPhone or iPod touch gives more priority to Japanese than English, iStellar will display everything in Japanese. This could happen if you're using a third language, e.g. French.

To avoid this issue, go to your iPhone / iPod touch's Settings > General > International > Language, and select English. After that, go back and set it again to your main language.
