MuyVerbs is a mobile app built for English speakers learning Spanish in Spain. Where Duolingo teaches generic vocabulary, MuyVerbs hyper-focuses on what actually makes you sound non-fluent: verb conjugation. Each session takes 5 minutes, drills present/preterite/subjunctive across 50+ irregular verbs (ser, estar, ir, tener...), and adapts to where you struggle. Built by a Swiss expat in Barcelona for fellow expats, students, and anyone preparing for DELE B2/C1 exams. Free on iOS and Android.
