FAQ
Propeller covers NFL, NBA, MLB, NHL, EPL, MLS, and PGA. Every game day, our engine analyzes hundreds of player props across all seven sports and ranks them by confidence.
Tipsters give you a pick and ask you to trust them. Propeller shows you exactly why each pick is recommended — which agents agree, what the injury impact is, and how confident the engine is. Full transparency, no black boxes. You see the reasoning before you play.
Yes. Propeller is a research and analysis tool — we don't accept wagers or handle money. Using data analysis to inform your pick'em picks is legal in all US states. You play on your own licensed platform of choice (Pick6, Underdog, PrizePicks, FanDuel, or any sportsbook).
Free users get 5 fully-analyzed props per day, 1 AI-generated parlay, and basic odds comparison. No credit card required to create a free web account.
Absolutely. Premium starts with a 7-day free trial, and you can cancel anytime from your billing settings. If you subscribe through the iOS companion app, you can also manage it in Apple subscriptions.
After every week of games, our system grades every prediction against real player stats. It then backtests different agent weight configurations and automatically adjusts which agents get more or less influence. Agents that were accurate get promoted; agents that were wrong get demoted. This means the model continuously improves — the public track record moved from the low-40s at launch to the mid-60s today.
That's our verified hit rate across over 91,000+ graded NFL, NBA, MLB, NHL, EPL, MLS, and PGA player prop legs from the 2025 and 2026 seasons. Every prediction is logged, graded against real results, and tracked — no cherry-picking.
