Learn Swahili

This is the only swahili app that asks for dialect and built for diaspora east africans in mind I love that. However, I don't think I'm learning very well with only situational modules. I know a ton of phrases already but I can hardly speak sentences on my own if I'm not too familiar with grammar, pronouns, demonstratives, and the difference in sentence structure English vs. Swahili. Feels like I only know some stock phrases and single words, without anyway of joining or remiximg them.
