HaterPicks vs betstamp
Both help you bet with more information, but they lead with different things — bet tracking and odds comparison versus player-prop projections and a graded accuracy record. Here’s a fair, feature-by-feature look for US bettors.

What a bet-tracking tool does well
betstamp is built around recording your bets and comparing odds across sportsbooks. Knowing your real profit and loss — and where the best price sits — is genuinely valuable, and something every serious bettor should do. Its own site says tracked bets are settled automatically and results are broken down by ROI and closing line value. The things worth checking are which of your sportsbooks it covers in your state, and whether you also want a model’s projection on top of the tracking.
Where HaterPicks leans
HaterPicks includes a bet tracker and a bet-slip scanner, but its center of gravity is the model: projection engines for player props, every projection graded against the result, and each sport's hit rate published with its sample size. It compares live prices across 14 US sportsbooks and prediction markets in American odds, with a same-game parlay builder on top, and it has no affiliate links. If you want tracking plus a projection model in one place, that's the pitch.
