Live spin pricing
Goal price, break-even, and plan-% suggestions that update as value leaves the board — show-wide, not guesswork.
Built for Whatnot live sellers
Run surprise sets without the spreadsheet chaos.
Grumpy Vet tools help streamers price spins, track real P/L after fees, manage packs & mini-breaks, and keep the board under control while you’re live.
Login required · Mobile-friendly · Built for live shows
Everything you need mid-stream
Built from real Whatnot surprise-set workflow — not a generic inventory app.
📊
Real P/L after fees
Track revenue, platform fees, and COGS as spins clear. Know if you’re ahead before the show ends.
📦
Packs & mystery hits
Envelope / pack mode for sealed prizes. Export pack names to Whatnot; reveal real COGS when the show wraps.
🎡
Mini-breaks
Split big boards into multiple wheels, keep one show total, and move on when a break is done.
📋
Whatnot-ready export
Copy the board as individual lines, hits first, optional shuffle — paste straight into your surprise set.
📱
Phone + desktop
Dark, tap-friendly UI for the phone in your hand and the laptop beside OBS.
Built for people who actually run the wheel
If you’ve ever raised spin price mid-show because a big hit left early — or realized too late the fees ate the margin — this is for you.
- Whatnot / live auction sellers running surprise sets
- Coin, silver, breaks, and collectibles streamers
- Hosts using packs so the board doesn’t die on one hit
- Sellers who want numbers, not vibes, for spin cost
