Dock with a plan, not guesswork. BerthReady helps boat owners, skippers and crews prepare for the final approach. Combine your boat profile, saved berth, forecast wind, marine current guidance, available space and crew setup into a clear, explainable pre-berthing briefing. PLAN AROUND YOUR BOAT Create a reusable boat profile with the handling details that matter during low-speed maneuvering, including propulsion, prop walk, thrusters, windage and normal crew size. SAVE THE BERTHS YOU USE Store marina coordinates, dock-line direction, water side, berth type, dock height, hazards and local approach notes. Reuse the same berth geometry whenever you return. UNDERSTAND THE CONDITIONS Optionally load wind information from Apple Weather and marine current model guidance from Open-Meteo. BerthReady converts these readings into dock-relative effects, helping you understand how forecast conditions may influence the approach. Every automatic reading includes its source, age and confidence level and remains subject to local verification. Manual condition entry is always available. COMPARE THE NEXT 24 HOURS Use Docking Window to compare forecast wind, gusts and dock-relative effects over the next 24 hours. Conservative Low, Elevated and High classifications help you compare forecast periods without claiming that any time is guaranteed safe. BUILD AN EXPLAINABLE PLAN Generate a structured briefing for alongside and finger-pier approaches. Review: • Approach strategy • Fender placement • Line preparation • Crew assignments • Ordered preparation steps • Early abort triggers • Alternative actions • The conditions and rules that influenced the plan BRIEF THE CREW Open a large-type Crew Briefing before the final approach. Keep roles, lines, fenders, hazards and abort conditions clear, then share the briefing as a locally generated PDF. LEARN FROM EACH ARRIVAL Record post-docking observations about wind response, prop walk, low-speed control and thruster effectiveness. Future plans can apply these observations and explain when they influenced the result. PRIVATE AND OFFLINE-FIRST No account is required. Boat profiles, berths, calibrations and saved plans remain on your device. Once subscription access has been verified, the core manual planning tools can work offline. Network access is required for purchases, restoring purchases, subscription verification and automatic weather or marine conditions. SUBSCRIPTION ACCESS BerthReady requires an active monthly or annual subscription. Eligible new subscribers can begin with a 7-day free trial. The trial automatically converts to the selected subscription unless it is cancelled at least 24 hours before the trial ends. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period. Payment is charged to your Apple Account. You can manage or cancel your subscription at any time from your App Store account settings. Available plans and prices are shown in the app and may vary by country or region. IMPORTANT BerthReady is an educational and pre-berthing planning aid. It is not a chartplotter, navigation system, autopilot, vessel-control system or substitute for the skipper’s judgment. Forecasts and marine model guidance may not represent actual conditions inside a marina. Always verify wind, current, visibility, traffic, local rules and the abort route at the berth. If conditions are uncertain or unsafe, delay the approach, abort early or seek qualified assistance. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is review sentiment: iNavX at 44% against BerthReady's 0%. iNavX also leads on rating (4.8 vs 1.0) and monetization model (free with in-app purchases vs subscription). BerthReady's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.
