The check-engine light your boat never had. Deckhand reads the engine data already flowing through your Simrad, Lowrance, or B&G display — RPM, coolant temp, oil pressure, voltage, fuel rate — and turns it into predictive maintenance intelligence a boat owner can actually use. Every trip logs itself the moment your engine cranks. Every reading gets analyzed against how your specific engine should behave. Wear that would never show up on a gauge — coolant creeping up 0.2° per trip, oil pressure sagging at cruise, alternator dropping under load — becomes visible before it becomes a problem. WHAT YOU GET • Live engine dashboard from your MFD — RPM, coolant temp, coolant pressure, oil pressure, battery voltage, fuel rate, gear position • Automatic trip logging — trips start and end themselves based on engine RPM • GPS route recording on the trip map • Engine hours tracked to the second, per engine • Maintenance log that stays with the boat • Adaptive service intervals — impeller / oil / anodes tuned to how you actually run, saltwater vs freshwater • Alerts when a reading crosses a real threshold, not an arbitrary number DECKHAND PRO Unlock the predictive intelligence: • Failure-mode detection — catches impeller wear, thermostat drift, and alternator sag as they develop • Predictive Health Engine — trend slopes, wear factor, cruise-band analysis • Engine Diagnostics — RPM distribution, health trends, oil-vs-RPM correlation • Unlimited trip history — every voyage preserved, charted, searchable • Resale PDF report — the Carfax equivalent for your hull • Adaptive alerts — service reminders that know how hard you actually run the engine $9.99/month or $59.99/year. Cancel anytime. Free tier includes the live dashboard, your 5 most recent trips, and basic alerts. WORKS WITH Deckhand connects to Navico-family multifunction displays (Simrad, Lowrance, B&G) built from 2015 forward, using the GoFree Tier 2 protocol over WiFi. No adapters, no dongles — just your phone and your MFD on the same network. Works with Mercury and Yamaha engines routed through a compatible display. WHY DECKHAND Boat engines don't have check-engine lights. They have gauges you glance at, sensors that fail silently, and a service schedule that assumes you run at 3200 RPM in freshwater. Deckhand replaces that with real data — from your actual engine, in your actual water, at your actual throttle — and turns it into intelligence you can act on before something breaks. Built by a boat owner. Made in San Diego. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is rating: Deckhand! at 5.0 against HVACsim's 2.6. HVACsim's advantage is ratings volume (10 vs 1) and iOS requirement (13.4 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Deckhand! holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: HVACsim has 10 ratings behind it against 1, so its average is the more settled of the two.
