Read full description

RadarCop is a professional radar plotting assistant designed for mariners, deck officers, cadets, and bridge teams. The app helps perform manual radar plotting calculations using own ship and target observations. Enter three radar observations, assess relative motion, calculate CPA/TCPA, test trial maneuvers, save plotting history, and export a clean PDF plotting sheet. Main features: β€’ Own ship course and speed input β€’ Target bearing and range observations β€’ Three-point radar plotting workflow β€’ CPA and TCPA calculation β€’ Target course and speed estimation β€’ Trial maneuver calculation β€’ Optional trial delay logic β€’ Relative motion assessment β€’ Radar-style plotting board β€’ Calculation history β€’ PDF export for record keeping or training β€’ Built-in Help & User Guide RadarCop is useful for training, bridge preparation, radar plotting practice, and quick cross-checking of manual calculations. Important notice: RadarCop is a calculation aid only. It does not replace official navigation equipment, ARPA, ECDIS, radar, COLREGs, company procedures, or the professional judgment of the Officer of the Watch. All navigational decisions remain the responsibility of the vessel’s bridge team.

YoSC is a secure connection built for seafarers. Ship networks are hard. VSAT and Starlink links are shared by the whole crew, they change as you move, and connections drop for no obvious reason. YoSC is built specifically for that environment. ONE TAP Open the app and tap once. No servers to choose, no ports to configure, no settings to learn. FINDS THE BEST ROUTE, EVERY TIME YoSC probes every server and port in parallel and connects through the fastest one that actually responds - on each new network, automatically. When you move from the mess room Wi-Fi to the bridge, it re-checks and adapts. EUROPE AND US Pick a region or leave it on Auto and let YoSC choose the fastest reachable node for you. UNLIMITED DATA No caps, no throttling, no fair-use asterisk. PRIVACY BY DESIGN We do not log your browsing history, the sites you visit, your DNS queries, or the contents of your traffic.

The clearest difference is in-app purchases: RadarCop at none against YoSC's 1. RadarCop also leads on update cadence (daily vs weekly). YoSC's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price and ads there is nothing between them.
