Go to the beach often or are planning a visit? You could be walking into danger. Rip currents are fast, narrow channels of ocean water that can drag swimmers out to sea in seconds. They’re hard to see and can strike even in sunny weather and calm-looking waves, causing hundreds of deaths each year. Rip currents are hard to see, but RipGuard makes them visible. 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. RipGuard brings peace of mind for families and beachgoers. Perfect for parents with small children. Protect yourself and your loved ones with RipGuard. It’s quick, easy, and could save your life. Swim Safe. Save Lives. Use RipGuard. New users receive 3 free scans. Subscription is required for continued use and for access to the rip current map.

Verdict

The call

The clearest difference is ads: RipGuard at none against PDF Reader's shown. RipGuard also leads on rating (5.0 vs 4.7). PDF Reader's advantage is update cadence (every 8 days vs every 2 months) and ratings volume (665 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.
