Prop Professor vs OddsShopper: Is Custom EV Worth More Than Convenience?

The Bottom Line

Prop Professor lets you control exactly how your +EV calculations are built. You choose the devigging method, assign weights to specific sportsbooks per market, and decide which books count as sharp. OddsShopper Portfolio EV runs a proprietary model that handles the math for you, which is convenient but gives you no say in the inputs. For bettors who want to refine their process over time rather than trust a black box, Prop Professor is the better tool at half the price.

Prop Professor scored 4.5 overall with a 4.8 for ROI potential and a 4.7 for features. The All Access plan at $49 per month includes customizable +EV and arbitrage detection, real-time odds updated every two seconds across 28+ sportsbooks, notification alerts for profitable bets, one-click sportsbook integration, and a DFS alt-line optimizer that supports PrizePicks, Underdog, Sleeper, and eight other platforms. The platform covers 15 sports including NFL, NBA, MLB, NHL, UFC, WNBA, CFL, tennis, soccer, and esports. Desktop only is a limitation, but the depth of customization and data quality competes with tools costing twice as much. Read our full Prop Professor review for the complete breakdown.

OddsShopper Portfolio EV scored 4.4 overall with a 4.6 for ease of use and a 4.5 for features. It delivers a proprietary +EV model that flags positive expected value and arbitrage opportunities, a portfolio builder that lets you customize betting portfolios based on risk tolerance, direct bet slip integration with one-click betting, DFS and pick'em tools for Underdog and PrizePicks, and a subscriber Discord for strategy discussion. Mobile apps on iOS and Android are a genuine advantage over Prop Professor's desktop-only setup. At $99.95 per month, OddsShopper is the more expensive option, and the feature gap does not justify the price difference. See our full OddsShopper review for the detailed assessment.

Quick Comparison

Features: Prop Professor provides customizable +EV calculations with adjustable sportsbook weights per market, real-time odds across 28+ books updating every two seconds, arbitrage detection with one-click sportsbook links, notification alerts for high-EV bets, and a DFS alt-line optimizer covering 11 platforms. OddsShopper Portfolio EV provides a proprietary +EV model, portfolio-style bet tracking based on risk appetite, arbitrage detection, direct bet slip integration, DFS tools for Underdog and PrizePicks, and parlay optimizer insights.

Usability: OddsShopper scored 4.0 for UI and 4.6 for ease of use. Prop Professor scored 4.2 for both. OddsShopper has iOS and Android apps plus a web interface. Prop Professor is desktop only. OddsShopper's onboarding is smoother, but its UI has been flagged as clunky in testing. Prop Professor's odds screen could use UX improvements, but the core tools are powerful once you learn the layout.

Value: Prop Professor All Access costs $49 per month. Use code BETSMART for 25% off your first month, bringing it to $36.75. OddsShopper costs $99.95 per month or $29.95 per week, with 50% off available (no code needed). Even at half off, OddsShopper's effective monthly cost is roughly the same as Prop Professor's full price, and Prop Professor offers more customization and a DFS optimizer that OddsShopper does not have.

What Makes Prop Professor Better

1. Customizable EV Calculations That No Other Tool at This Price Offers

Prop Professor's custom devigging is the most significant feature separating these two tools. You assign your own sportsbook weights per market, choose your devigging method, and decide which books to trust as sharp on a per-sport basis. If you think Pinnacle sets the sharpest NFL lines but Circa is better for NBA totals, you can build that into the math. OddsShopper runs a proprietary model that handles the calculations for you. That is easier to use, but it means you cannot adjust the inputs or validate the methodology. For bettors who want to understand and control the math behind their +EV bets, Prop Professor gives you that control at $49 per month while OddsShopper charges $99.95 for a model you cannot inspect.

2. Real-Time Odds That Update Every Two Seconds

Prop Professor's odds screen refreshes every two seconds across 28+ sportsbooks, including niche books like Novig, OnyxOdds, and ProphetX. In +EV betting, speed matters. A line that shows 3% expected value can disappear in under a minute as the market adjusts. OddsShopper has real-time odds as well, but Prop Professor's refresh rate and niche book coverage give it a measurable advantage when you are trying to capture opportunities before they close. The customizable odds display lets you filter by sport, market, and sportsbook so you see exactly the data you need without scrolling through irrelevant markets.

3. A DFS Alt-Line Optimizer That OddsShopper Cannot Match

Prop Professor's DFS optimizer calculates expected value for alternative lines on PrizePicks, Underdog, Betr, Dabble, DraftKings Pick6, Sleeper, and five other platforms. It flags bets where the math favors you based on each site's multipliers, and notification alerts let you know when new +EV fantasy bets appear without sitting in front of the screen. OddsShopper has DFS tools for Underdog and PrizePicks, but they are basic value projections, not an optimizer that calculates EV against alt lines. If you play DFS alongside sports betting, Prop Professor's optimizer is a feature you will use daily that does not exist anywhere else at this price point.

When OddsShopper Is Better

You Need Mobile Access for On-the-Go Betting

OddsShopper has native iOS and Android apps that give you full access to +EV opportunities, portfolio tracking, and bet placement from your phone. Prop Professor is desktop only. During a live NFL Sunday or a busy MLB slate, being able to pull up your +EV screen on your phone and act on a line movement without opening a laptop is a real workflow advantage. For bettors who do most of their research and betting from their phone, OddsShopper removes that friction entirely.

You Want Portfolio-Style Bet Tracking Built Into the Tool

OddsShopper's portfolio builder lets you create custom betting portfolios based on risk tolerance, track profit and loss over time, and monitor closing line value on your bets. The tracking is manual entry, but the portfolio framing helps you think about your betting as a whole rather than bet by bet. Prop Professor does not have built-in bet tracking, so you would need a separate tool or spreadsheet to monitor your performance. If integrated tracking matters to your workflow, OddsShopper handles it within the same platform.

You Prefer a Simpler Onboarding Experience

OddsShopper's interface is designed to surface +EV bets quickly without requiring you to configure devigging methods or sportsbook weights. You open the tool, see what the model flags as profitable, and bet. Prop Professor's customization is powerful but adds a learning curve. If you want a tool that works out of the box without configuration, OddsShopper is easier to start using on day one.

Pricing

Prop Professor offers three plans. All Access costs $49 per month and includes everything: +EV, arbitrage, real-time odds, and the DFS optimizer. Fantasy-only costs $35 per month for just the DFS tools. Sportsbook-only costs $35 per month for +EV, arbitrage, and odds without DFS. Use code BETSMART at checkout for 25% off your first month, which brings All Access to $36.75 for month one.

OddsShopper Portfolio EV costs $99.95 per month or $29.95 per week. The annual plan is $1,198 per year, which works out to roughly $99.83 per month with no meaningful discount from monthly billing. A 50% off promotion is currently available with no code needed, bringing the effective monthly cost to approximately $49.98.

The math is straightforward. Prop Professor at $49 per month delivers customizable +EV, real-time two-second odds, arbitrage, and a DFS optimizer. OddsShopper at $99.95 delivers a proprietary +EV model, portfolio tracking, and mobile apps. Even with OddsShopper's 50% discount, the effective price roughly equals Prop Professor's full price, and Prop Professor still offers more customization and the only DFS alt-line optimizer in this price range. Over a full year without discounts, Prop Professor at $588 costs less than half of OddsShopper at $1,198.

Can These Tools Pay for Themselves?

The ROI question comes down to how consistently you use the data each tool provides. Prop Professor's two-second odds refresh alone can prevent you from taking stale lines, which over a season of regular betting adds up in vig savings. The customizable EV calculations let you build a process that gets sharper over time as you learn which sportsbook weights produce the best results for specific markets. OddsShopper's portfolio approach helps you think about risk management across your total betting activity, which is a useful framework even if the individual +EV calculations are less customizable.

At $49 per month, Prop Professor sets a reasonable bar. One or two better line shops per week based on the real-time odds screen can offset the monthly cost through reduced vig alone. OddsShopper at $99.95 requires roughly double the usage to justify the subscription. Neither tool makes betting profitable by itself. Both improve the information going into each decision.
