SmartTrimApp

Better trim you boat, without guesswork. SmartTrim uses your iPhone to give live pitch, roll, and hull-specific trim guidance — no external sensors needed.

SmartTrim helps you set the right boat trim for safer, smoother, and more efficient rides — without guesswork, no external sensors.

Designed for skippers and serious marine enthusiasts, SmartTrim provides clear, readable trim guidance based on your speed and hull type, so you can focus on the water, not the instruments.

How it works

• SmartTrim uses a precise calibration and algorithmic system to deliver reliable, consistent readings on every trip.
• During setup, the app guides you through a short calibration process that aligns pitch, roll, and trim sensing to your boat’s unique geometry. In operation, SmartTrim processes motion and speed data in real time, applying filtering and correction logic to reduce noise and compensate for sea motion.
• For best accuracy and safety, your phone must be securely mounted and should not be handled while underway. The result is stable performance data and trustworthy trim advice in real-world conditions.

What you get

• Live trim advisory with clear target guidance
• Hull-type–specific logic: Planing, Semi-Displacement, or Displacement
• Clean, stable dashboard designed for bright sun and rough water
• Readable typography with Dynamic Type support
• Fuel economy awareness through efficient trim guidance
• The interface stays familiar and calm — no clutter, no gimmicks.

Safety notice

SmartTrim provides advisory information only. It is not a substitute for seamanship, navigation systems, or official charts. Always maintain a proper lookout, comply with local regulations, and use your own judgment for conditions, loading, and crew comfort.
