Talking about apps I would recommend MosaLingua (digiSchool), it helps me for English and Spanish.

It’s mainly design to learn vocabulary (spaced repetition), the app is free, only class/courses may required a subscription.

Answering your initial question you can select the “native” language you want, but I’m afraid you won’t find your mother tongue.
