Not free

The app is indeed free, but according to the play store listing ...

PLEASE NOTE
You'll need a Babbel subscription in order to access courses and features. The number of courses offered may vary depending on which display language you use.

Choose from four convenient subscription options:

One-month subscription for $12.95
Three-month subscription for $26.85
Six-month subscription for $44.70
Twelve-month subscription for $83.40

Your subscription will renew automatically unless cancelled before the end of the current payment period. You can manage or cancel your subscription in your Google Play Store account.

Personally, I'm not a fan of automatically renewing subscriptions.
