Nu Stack is the all-in-one precious metals toolkit — scrap gold & silver calculator, portfolio tracker, AI coin identification, and refinery payout estimator. Powered by real refinery math. Start your new business, create a side hustle to hedge against geopolitics or just a fun hobby. The ONLY app on the market providing everything you need in 1 place.
I’ve spent a lot of time buying/selling gold and bouncing between spot sites, melt calculators, spreadsheets, and notes just to evaluate a single deal. This is the first tool I’ve seen that actually pulls that workflow together.
What stands out:
Real-time melt + profit calc with adjustable refinery payouts (not just spot × weight)
Handles mixed karat deals correctly instead of rough estimates
Shows a clear “max price to pay” so you’re not guessing in the moment
Deal grading + tracking over time so you can actually see if you’re improving
Full transaction logging with receipts, history, and performance view
New to physical gold dealing? No problem there is an AI agent to walk you through everything and offer continual guidance as well!
It feels less like a calculator and more like a system for running this day-to-day. Interested to see how it evolves, but this is a solid foundation.
