About O3

O3 creates environments that bring out the best in people. Unlock our 24/7 study cafés or study anywhere with friends using our social study timer. Stay focused, catch Oysters, and earn rewards like lifetime O3 café discounts. Android AccessibilityService usage disclaimer (optional): O3’s optional Focus Protection uses the AccessibilityService API during user-started study sessions to detect which app is visible. If you open a distracting app, O3 returns you to your device’s Home screen and shows a focus warning. App identifiers are processed on-device; O3 does not read, store, or share screen content. You can disable access anytime in Android Settings. The world is your oyster. You’ve got this!
