Questions

Frequently asked

CLARO is an iOS app that finds sports arbitrage opportunities — moments where two sportsbooks have mispriced the same event such that betting both sides guarantees a profit. We surface them in real time and help you place both legs at the books.
No. CLARO is a data tool. We surface opportunities and deep-link you to licensed sportsbooks where you place the actual wagers. We don't hold funds, take a position, or accept stakes.
Sometimes two sportsbooks disagree on the implied probability of an outcome, leaving a small profit margin if you bet both sides. CLARO calculates that margin in real time and only surfaces opportunities where the math works.
Each individual opportunity is mathematically guaranteed if both legs are placed at the displayed odds. In practice, odds move fast, books reject suspicious bets, and execution friction matters. CLARO gives you the edge — placing the bets correctly is on you.
We poll 100+ sportsbooks every 40ms. Push notifications fire within seconds of an opportunity appearing.
CLARO is available in most US states. We do not support: Utah, Hawaii, Idaho, Alabama, California, Texas, Georgia, Minnesota, Oklahoma, Mississippi, South Carolina. (Subject to change as state laws evolve.)
Yes. CLARO is for users 18 and older. Some states require 21+ for sports betting at supported sportsbooks — check your state's law.
CLARO+ subscriptions are managed through Apple. Cancel any time in iOS Settings → [your name] → Subscriptions.
