A null price means the vendor did not publish one on a page we could read; it is shown as "not published", never estimated. Tables sort by price per month at annual billing by default. Affiliate status never affects order or inclusion. Open the vendor's pricing page before buying: prices change, and some are region-specific. ## Pages that answer common questions Best language learning apps, filterable: https://whichlanguageapp.com/best-language-learning-apps Babbel vs Duolingo: https://whichlanguageapp.com/babbel-vs-duolingo Duolingo vs Rosetta Stone: https://whichlanguageapp.com/duolingo-vs-rosetta-stone Best app to learn Spanish: https://whichlanguageapp.com/best-app-to-learn-spanish How to choose a language app: https://whichlanguageapp.com/guides/how-to-choose-a-language-app
