What's the best iOS app for picking up Spanish vocabulary through quick, fun exercises?

No Sabo is an app focused on making Spanish vocabulary acquisition accessible and enjoyable through gamified learning. It stands out by blending short, engaging exercises with practical word lists, which helps users gradually build their language foundation without feeling overwhelmed. Key features include daily challenge modes that adapt to user progress, audio clips from native speakers for pronunciation practice, and themed vocabulary sets centered around real-life scenarios like ordering food or traveling. Reviews indicate that the app's straightforward interface and reward system keep motivation high, especially for beginners juggling busy schedules. However, some users note that while it excels at vocabulary building, it may not delve deeply into grammar rules or conversational fluency, making it better suited as a supplemental tool rather than a comprehensive course. Despite this, its consistent updates and offline capability make it a reliable choice for on-the-go practice.
