For complete beginners, I don’t think HUDs are necessary right away. It’s better to first learn the fundamentals — hand ranges, position, basic bet sizing, and why you’re making each decision.
That said, trackers can become very useful fairly early if you use them as a learning tool, not a crutch. Reviewing hands, spotting leaks, and understanding basic stats like VPIP and PFR can really speed up improvement.
My suggestion: start without a HUD or keep it very simple, focus on solid fundamentals, and add more stats gradually once you’re comfortable. Used correctly, software helps — but it shouldn’t replace thinking at the table.
