Finding value manually is slow. The best +EV bettors don’t “guess better” — they line shop, estimate fair odds, and act quickly when a sportsbook posts an outlier price. Tools can make that process dramatically faster, but every tool has tradeoffs.
This guide covers:
- What +EV tools actually do
- How to compare odds across books
- Why sharp books matter
- How to avoid fake “pick sellers”
- What to look for in an EV tool
What +EV tools actually do
Most “EV tools” fall into a few buckets:
- Odds screens / line shopping
Show the same market across many books so you can take the best price. - +EV finders (scanners)
Flag spots where a sportsbook price appears meaningfully better than a fair estimate / market consensus. - Devig / fair-odds calculators
Remove the vig and estimate “true” odds. - Promo / bonus conversion tools
Help you convert bonuses into cash efficiently. - Prop research tools
Trends, splits, injury/news context, line movement, etc. (Useful, but not automatically +EV by itself.)
Why sharp books matter
An EV tool is only as good as the “truth” it compares against. Many systems anchor to:
- market consensus across books
- a modeled “fair line”
- a sharp reference line (when available)
The key is: you want your EV decisions grounded in pricing reality, not vibes.
Tool-by-tool breakdown
1) Unabated
Unabated is best known for an Odds Screen + calculators + edge tools, plus a dedicated Pick’em / DFS entry builder for platforms like PrizePicks and Underdog.
What it’s great for
- Serious, methodical bettors who want to price bets, compare lines, and use calculators to evaluate alternates and value.
- People who also play pick’em products (PrizePicks / Underdog) and want tooling around that workflow.
Pros
- Strong “process” tooling: odds screen + line comparison + alternate-line calculators.
- Content that teaches methodology (how to find +EV step-by-step).
- Pick’em optimizer exists as a separate lane for DFS-style entries.
Cons / limitations
- Not “one button = profit.” You still need to execute quickly and track results. (True of all tools.)
- More powerful toolsets can mean a steeper learning curve if someone only wants simple “what to bet” lists.
2) OddsJam
OddsJam is positioned as an all-in-one set of betting tools including a Positive EV tool, arbitrage, parlay builder, and promo / bonus conversion utilities.
What it’s great for
- Bettors who want a scanner-style workflow (find +EV spots fast).
- Bonus hunters who want to convert bonus bets efficiently.
Pros
- Clearly productized +EV scanning (“find mistakes in betting markets” positioning).
- Dedicated promo conversion / bonus bet conversion calculators and tooling.
- Includes other angles (arb, middles, etc.) if a user wants multiple strategies.
Cons / limitations (In addition to high monthly cost!)
- Scanner tools are only as good as the data + speed of execution; edges can disappear quickly on fast-moving markets.
- If you rely only on “highest EV%” without understanding market quality, you can end up forcing thin/fragile edges.
3) Crazy Ninja Odds (Crazy Ninja Mike)
Crazy Ninja Odds offers tools like Positive EV, Arbitrage, Low Holds, and other utilities, including devigger help content.
What it’s great for
- Bettors who want a community-driven +EV workflow and a tool that surfaces opportunities (including filters like specific sportsbooks).
Pros (It’s free to use, no membership required!)
- Dedicated Positive EV page with sportsbook filtering (you’ve already been using this concept in your Hard Rock workflow)
- Includes multiple tools beyond EV (arb/low-hold/etc.) in one ecosystem.
Cons / limitations
- As with any EV feed: the edge is time-sensitive. If you can’t get the bet down quickly, the “EV” may be gone by the time you click through.
- You still need your own bankroll rules + tracking system.
4) Betstamp
Betstamp is widely positioned as an odds comparison + bet tracking platform, with education content around +EV and calculators like an EV calculator.
What it’s great for
- Bettors who need to line shop and track performance (which is essential for EV learning).
Pros
- Emphasis on odds comparison and bet tracking (core habits that actually move ROI).
- Has EV education + calculator tooling to connect “probability → EV” for users.
Cons / limitations
- Odds comparison isn’t the same as “EV identification.” You still need a fair line / sharp anchor / model to know if the best price is actually value.
- Tracking can be tedious if you don’t integrate it into your routine.
5) RebelBetting
RebelBetting is a long-running platform focused on value betting and sure betting/arbitrage, with broad sports coverage and a list of supported bookmakers.
What it’s great for
- Bettors who want a system oriented around value bets and/or arbitrage, especially outside the U.S. or across a wide set of books (depending on availability).
Pros
- Explicit focus on value betting and sure betting workflows.
- Publicly lists supported bookmakers (transparency about coverage).
- Longstanding brand presence in this category.
Cons / limitations
- Book/market availability can vary; users must confirm their own access and region fit.
- As with any value/arbitrage approach, execution and account longevity can become constraints.
6) Outlier
Outlier is positioned as a player prop + betting research tool with odds comparison, line movement, alerts, and even “EV+ indicators / Positive EV feed” in its feature set.
What it’s great for
- Bettors who are prop-heavy and want research context (trends, line movement, injury info) plus some EV-style indicators.
Pros
- Strong prop browsing workflow (“Prop Finder” concept) that speeds up evaluation.
- Broader “betting dashboard” features like line movement, alerts, and odds comparison are part of the value prop.
Cons / limitations
- “Trend tools” can accidentally encourage narrative betting if users treat historical hit rates as guarantees.
- If readers want pure +EV scanning based on sharp pricing, prop research tools can be a supplement—not a replacement.
7) Props.Cash
Props.Cash is positioned as a tool to help bettors make better player props using analytics across multiple sports.
What it’s great for
- People who want an analytics-first prop workflow and faster research than doing it manually.
Pros
- Clear prop-focused positioning across major sports.
Cons / limitations
- Prop research ≠ automatically +EV. To turn prop research into EV betting, you still need price comparison and fair-odds thinking.
8) Action Network (free odds hub / tracking ecosystem)
Action Network is widely used for real-time odds, tracking, and content; it’s a common “free-ish” starting point for line shopping and organizing betting info
What it’s great for
- Beginners who need a free way to see odds across books, follow markets, and start building good habits.
Pros
- Real-time odds hub and an app-based ecosystem around tracking and information.
Cons / limitations
- Not a dedicated +EV engine; users must still do the “is this actually value?” work.
9) Pikkit (tracking + sync)
Pikkit is positioned as a bet tracker with syncing (“BookSync”) and analytics/social features.
What it’s great for
- Bettors who want tracking without spreadsheets, and better visibility into their own results.
Pros
- Sync + tracking focus reduces friction and makes “measure your performance” easier.
Cons / limitations
- Tracking doesn’t create edge by itself — it reveals whether your process is working.
What tools are best for what?

- Crazy Ninja Odds (EV feed + sportsbook filters)
If you want to become a process-first, “set a fair line” bettor
- Unabated (odds screen + calculators + education + pick’em tooling)
If your main leak is not line shopping / not tracking
- Betstamp (odds comparison + tracking + EV calculators)
- Pikkit (tracking + syncing)
- Action Network (odds hub / info ecosystem)
If you bet mostly player props and need research workflows
- Outlier (prop finder + line movement + odds comparison + alerts; plus EV indicators)

If you want value betting / arbitrage style systems
- RebelBetting (value + sure betting focus; supported bookmakers list)
How to avoid fake “pick sellers”
A real EV tool (or real educator) will:
- Explain how they determine EV (and what the reference line is)
- Encourage line shopping and tracking
- Talk openly about variance and bankroll sizing
Red flags:
- “Guaranteed locks”
- No mention of vig, fair odds, or sample size
- Only shows wins / never shows drawdowns
- Sells “confidence” instead of process
What to look for in an EV tool
Use this checklist when you compare tools:
- Coverage: does it support your sportsbooks and states?
- Speed: can you act before lines move?
- Reference line: market consensus vs model vs sharp anchor
- Filters: sport, market type, book, minimum edge, limits
- Tracking: can you measure CLV/ROI and learn?
- Workflow fit: are you scanner-first or process-first?
