The longer answer
Mondly, now part of Pearson, is a daily-lesson app known for its chatbot conversations and augmented-reality lessons. Its forty-one languages are mostly European and Asian, plus Arabic, Hebrew, Persian and Afrikaans. Somali is not offered, and there is a Mondly Kids app only for a subset of those languages.
Mondly's lessons are the same across every language, translated from a common script, so even if Somali were added the content would be generic travel dialogue rather than Somali life.
Luuqad starts from Somali culture and works outward: food, family, the countryside, the market. It has no chatbot, and its conversations are the ones a child actually needs, such as greeting ayeeyo and asking for water.
What to use instead
For children and families, Luuqad is built only for Somali: 18 real-life topics, 250 words and phrases with native-speaker audio, a quiz for every topic, 12 games and a Grown-ups area. It is free to download on iPhone and iPad. Browse every word it teaches before you install anything.
For adults who want a large travel vocabulary fast, uTalk, Ling, LinGo Play also offer Somali content. Our alternatives page compares all of them honestly.
