Description
OddsGuard is a free Safari extension and iOS app that overlays real-time odds on 40+ of the biggest sportsbooks directly on the page you're already on and compares the odds against 78 of top bookmakers. Stop switching tabs. Stop guessing. Find better lines, savings, and +EV plays — automatically.
WHAT IT DOES
• Real-time odds overlay across 40+ sportsbooks while you browse
• Parlay comparison — see the same parlay's price across books
• +EV alerts — flags when a line is mispriced in your favor
• Bonus & promo tracker — never miss a free bet or boosted price
• Savings badges — instant dollar-savings vs. the book you're on
• Odds-format converter — American, decimal, fractional
• Region-aware — only shows books you can actually bet at
WHY IT'S DIFFERENT
Tools like OddsJam charge $200–$600/month. OddsGuard is free, forever. No login. No ads. No tracking. We make money via affiliate links to the sportsbooks you choose to use — never from your data.
You don't open a separate app. You don't paste in URLs. You browse a sportsbook in Safari like you always do, and OddsGuard appears on the page with the better price.
WHO IT'S FOR
• Casual bettors who want to stop overpaying without learning a new tool
• Sharp / +EV bettors who want a zero-effort alternative to subscription tools
• Parlay bettors who lose value to a single mispriced leg
• Anyone tired of opening 6 tabs to compare a moneyline
• Only supported on english only sites currently (Internationalization coming soon)
PRIVACY FIRST

Nouveautés (v1.0.5.3)
WHAT'S NEW IN THIS VERSION
Calculators
• New Calculators tab in the iOS app with fifteen betting tools — parlay, arbitrage, Kelly criterion, hold/vig, odds conversion, round robin, and more — matching the website calculator suite.
Safari Extension — Overlays & Comparison
• Oddschecker: comparison overlays now reflect OddsGuard's best price across all supported books and regions, not only the UK aggregate Oddschecker displays.
• Oddschecker match pages (tennis singles, football fixtures, Compare-All layouts) now show comparison badges on individual event pages.
• New Stake.com sportsbook support on sports, live, league, and futures pages.
• Outright/futures overlays expanded on Bet365, Betsson, BetOnline/LowVig, Betway, BetVictor, and BetParx pages that previously showed no badges.
• FanDuel sport hub tabs (Live Now, Upcoming, league views) resolve to the correct sport when the page URL drops query parameters.
• Compare All and best-price badges now rank only books on the same point spread or total line as your selection.
• Spread and total quotes with unrealistic modelled value are filtered from rankings unless freshly updated.
Safari Extension — UI Reliability
• Floating action button menus and bonus panels are isolated from aggressive sportsbook CSS so icons, fonts, and card layouts render correctly on sites like BetVictor, BetUS, and 1xBet.
• Modal dialogs opened from the bonus panel (Compare All, forms, detail views) are similarly protected from host-page style overrides.
• Compare All and Parlay Compare modals scroll properly on mobile Safari; parlay disclosure can be collapsed to see more pricing rows.
Location & Compliance
• Geolocation requests allow more time on slow networks before timing out, with faster automatic retry after transient failures.
• Location cookie refreshes when your network IP changes (travel), reducing stale region detection.
• Parlay calculator age badge (18+/21+) uses the same cached location as the floating action button for faster, jurisdiction-correct display.
• Safari iOS privacy consent now shows separate, explicit copy for the host app versus the Safari extension — accepting in one surface does not imply consent in the other.
Other Improvements
• Sport and lobby detection improved on URLs with ad/tracking parameters and hash-routed sportsbook pages.
• Alt+Shift+O keyboard shortcut now toggles overlay visibility on desktop browsers.
• iOS onboarding and Activate-tab improvements from prior release continue to refine first-run setup and extension enablement guidance.
