The longer answer
Rosetta Stone is the oldest name in language software, known for its immersion method: no translation, just pictures, sounds and sentences in the target language. Its catalogue of twenty-five languages covers the world's largest languages plus a few smaller ones such as Irish, Hebrew and Filipino. Somali is not on the list, and the list changes rarely.
Rosetta Stone did once build custom courses for endangered and indigenous languages through a community programme, but those were commissioned by the communities themselves, and no Somali course came out of it.
Luuqad shares Rosetta Stone's belief that pictures and native voices beat translation drills, especially for children. Its lessons connect every Somali word to an illustration and a native recording, then test understanding with picture, listening and matching quizzes, which is immersion at a child's pace.
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.
