The longer answer
LinGo Play is a flashcard app with an unusually large catalogue, and it includes Somali. Its Somali course is a big set of word and phrase cards with translations and audio, practised through flashcard games and online word battles against other users.
For an adult who enjoys drilling, it is a legitimate way to build a large vocabulary. The content is a word list rather than a curriculum, and the design and competition features are aimed at adults.
Luuqad teaches fewer words with more context: illustrations of Somali life, native audio, example sentences, topic quizzes and games designed for children and families.
What to use instead (or alongside)
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 also offer Somali content. Our alternatives page compares all of them honestly.
