RadarCop vs Maritime Converter Pro

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: • Own ship course and speed input • Target bearing and range observations • Three-point radar plotting workflow • CPA and TCPA calculation • Target course and speed estimation • Trial maneuver calculation • Optional trial delay logic • Relative motion assessment • Radar-style plotting board • Calculation history • PDF export for record keeping or training • 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.

Fast offline conversions for bridge, engine-room and cargo work. Maritime Converter Pro puts useful marine, pressure, fuel and engineering calculations in one focused app. FREE TOOLS • QNH and pressure: convert hPa, inHg, mbar, kPa, mmHg, psi, bar and atm. • QFE to QNH: estimate sea-level pressure from field pressure, elevation and temperature. • Bunker quantity: convert barrels or other volume units to mass using the density you enter, and convert mass back to volume. • Marine and engineering units: 24 searchable groups and 100+ units, including distance, speed, mass, volume, pressure, area, time, angles, temperature, power, flow, viscosity, torque and energy. • Sea time and ETA: calculate voyage time and estimated arrival from distance, speed and departure time. • Diesel density: estimate density at a different temperature and calculate mass from volume. • Stowage factor: convert m³/t and ft³/long ton, allow for broken stowage, and estimate cargo quantity from usable volume. BUILT FOR PRACTICAL WORK • Works offline after installation. • Clear input units and calculation results. • Quick access to QNH from the home screen. • No account is required for the free calculators. LIFETIME PRO One non-consumable purchase unlocks unlimited calculation history, favorites and result sharing. Every calculator listed above remains free. The App Store shows the final local price before purchase. IMPORTANT QFE-to-QNH and diesel-density results are estimates based on the values and assumptions shown in the app. They do not replace approved operational tables, instruments, cargo documents or professional procedures. Verify critical calculations against the standards required for your operation.
