Hi Product Hunt! 👋 I'm Subir, a Power BI and data analytics developer with over 8 years of experience. Every Power BI learner eventually hits the same wall: a measure that should work returns (Blank), and understanding a single DAX function means digging through docs, forums and videos. Most DAX resources also assume you're at a desktop with time to spare. I built DAXionary to make DAX easier to learn, anywhere: • All 350 DAX functions in 14 categories, explained in plain English with one-tap copyable syntax and real measure patterns • An offline DAX Assistant that answers questions with working code, running entirely on your phone • A Measure Builder with 22 ready-made patterns (running totals, rankings, year-over-year and more) using your own table and column names • Timed quizzes to check what you've actually learned It's completely free, with no ads, no sign-ups and no tracking, and it's available on Android today. I'd love your feedback: what would make DAXionary more useful for you or your team? And which DAX function gave you the most trouble when you started?
