Betwatch vs OddsShopper: questions

Is there an OddsShopper alternative for +EV player props?

Yes. Betwatch's +EV board ranks player props from sportsbooks, prediction markets and pick'em apps against a devigged fair line, and Trends puts the player's hit rate over their last 15 games next to the edge and every book's price.

Does OddsShopper compare player prop odds across sportsbooks?

OddsShopper lists Stokastic Props as an upgrade in its subscription and builds pick'em entries for PrizePicks, Underdog and Sleeper. Betwatch shows each tracked book's player props side by side with the best price flagged, every prop's line history and the player's hit rate beside the price.

What are some alternatives to OddsShopper for comparing sportsbook odds?

Betwatch compares 42 odds sources (27 sportsbooks, 9 prediction markets and exchanges and 6 pick'em apps) with the best price flagged and every book's line history. Unabated, Action Network and Covers are other sites that show odds from several sportsbooks.

Does Betwatch have arbitrage tools like OddsShopper?

Betwatch has an arbitrage calculator and flags the best price on each side of every market, so a gap between two books shows on the same row. OddsShopper sells pre-game and in-game arbitrage scanners that list the arbs for you.

Is OddsShopper worth it?

It is worth it if you want arbitrage and in-game scanners, the Liquidity Tool or Tails expert picks in one subscription. If you mostly want +EV props with hit rates and the full price history of each book, Betwatch covers that.

Can I use Betwatch and OddsShopper together?

Yes. A bettor can scan for arbitrage or in-game spots in OddsShopper, then open Betwatch to see how the price moved at each book and what the sharpest books pay before betting.
