Babbel is built for adults who want to reach conversational level in a major European language, with dialogue-based lessons, grammar explanations and live classes. It is very good at that. It does not teach Somali and, with only fourteen languages after more than a decade, it is unlikely to.
Luuqad is built for Somali only, and for children first. The lessons are pictures, native audio and quizzes rather than grammar tables; the games are about Somali life; and parents get a Grown-ups area to follow along. Heritage speakers who understand Somali but freeze when speaking find the vocabulary topics rebuild confidence quickly.
