RipGuard uses AI to detect rip currents in real-time: directly on your device, no internet required. Just open the app, point your camera at the water, and scan for danger. Our AI model is trained on 4,995 rip current images and achieves 92% detection accuracy. See where others have reported rip currents on our live geomap, and stay informed with crowdsourced alerts from other beachgoers. Contribute to the community with your own scans as well.
