We fixed the iPhone 5 issues and all 3 versions are back on the app store!
I've stopped Kanji Connect sales on the appstore temporarily while we add iPhone5 graphics. The app wasn't starting on iPhone5 due (we think) to a new rule from Apple that all apps support iPhone5 format. It should be back up within a week or so.
Kanji Connect apps (full version, lite JLPT N5 version, 25-kanji free version) came out the other day!
If you like'm please do support them with FB likes and app store reviews - it all counts and is much appreciated! As an independent developer I have to count on word of mouth for promotion!
