Betwatch vs The Odds Gap: questions
The Odds Gap vs Betwatch: what is the difference?
The Odds Gap is built around gaps between a book's price and a fair line, with alerts and hedge tools. Betwatch puts every book's price, its line history from open to close and a +EV board on one screen, with public pages for every league, team and game.
How much does The Odds Gap cost?
Its pricing page lists a free tier with no sign-up and a paid plan at $7.99 a month or $79 a year. A founding price of $5 a month or $49 a year was offered at the time we read it.
Does The Odds Gap have historical odds data?
Its site sells historical odds data as a separate plan from the website plans. On Betwatch every price change at every book is recorded from the open to the close, so a finished game's game page shows the opening and closing line by book.
How does The Odds Gap work out its fair line?
It uses Pinnacle and prediction-market prices and removes the margin. Betwatch builds its fair line from the sharpest books and removes the vig with the power method, and each bet lists the books behind its fair price.
Does The Odds Gap show player props?
Props are one of the markets on its board. Betwatch lists player props on every game page with each book's over and under and the best price flagged, and the +EV board ranks them against a fair line.
Can I use The Odds Gap and Betwatch together?
Yes. Use Betwatch to see every book's price and how the line moved, and The Odds Gap if you want gap alerts or a bet tracker next to it.
