Hobby Heat Index sweeps 38,000+ athletes every morning and tells you who's breaking out — before the PSA 10s double and everyone else figures it out.
Timing is everything in the card hobby. By the time a player's name is trending on social media, their PSA 10s have already doubled. The collectors who win are the ones who know before everyone else — but that takes hours of research across sports news, stats, and market data every single day.
Most collectors don't have that time. We built Hobby Heat Index so you don't need it.
Every morning before you wake up, we've already gone through the sports news, box scores, eBay sold data, and social chatter for 38,000+ athletes across the NFL, NBA, MLB, NHL, WNBA, and college sports — and flagged the ones worth acting on with a Heat Score and a signal: BUY, HOLD, WATCH, or SELL.
0–100 signal strength score. Combines news velocity, recent performance, and card market momentum into one number.
BUY / HOLD / WATCH / SELL signals updated every morning at 6 AM UTC. High-tier athletes get rescored within 30 minutes of a game ending.
Can't wait until tomorrow? Paid users can trigger an instant rescore for any athlete at any time.
Track the cards you actually own. Get alerted when a signal changes on anything in your collection.
"Card Ladder tells you what sold yesterday. We tell you who to target today — before prices move."
Platforms like Card Ladder and 130point are great for sizing a deal once you know who to look for. We're the step before that: figuring out which athletes are worth targeting in the first place. Use us to find the target, use them to price it. We see them as complements, not competitors.
We also publish our win rate. Every BUY call gets checked 30 days later against what actually happened — and you can see exactly how often we're right before you pay a cent. If a sport has a bad month, you'll see it in the accuracy breakdown. No cherry-picking.
This is for collectors who track what they own, flip with purpose, and hate being the last to know. If you're running a card portfolio, buying to resell, or managing inventory at a shop, having a daily intelligence edge is how you stay ahead of the market.
Free users get the full leaderboard and top signals — no account required. Paid tiers unlock personalized PC alerts, on-demand rescores, card comp data by grade, and — for shops — a live radar display for your TV so customers can see what's hot right now on the floor.
This started as a personal tool to stop missing breakout windows on players I was already tracking. The manual research workflow — checking beat writers, box scores, eBay sold listings, and social chatter every morning — was taking 45 minutes a day and still missing things.
After automating it with AI, the signal quality was good enough to share. Hobby Heat Index grew from there.
