Currently, Asken Diet is only available in English. We'd like to add more languages in the future but before we could do that, we'd have to update the advice text and localize the language and take in to account cultural food habits in to the advice text. We would also need to purchase food database details for each new country we localize for so that users can find food common in their country. We have a long list of features still to add to the English version which we are prioritizing before localizing in to additional languages.
Comment below if you want us to localize in to your language so we can see which language we should think about adding when the time comes.
Please note, we do have a Japanese version of our app called あすけん. It is only available on the Japanese app stores (iOS/Android) and it is a separate app from the English version.
