Getting perfect crown molding joints shouldn't require guesswork or complicated math. Crown Molding Calculator gives you precise miter and bevel angles instantly — right on your job site. Whether you're a professional trim carpenter, contractor, or a dedicated DIYer tackling your first crown molding project, this app eliminates the frustration of figuring out compound miter saw settings. Enter your wall corner angle and spring angle, and get exact cut settings in seconds. WHAT YOU GET: • Instant miter and bevel angle calculations for any wall corner (60°–145°) or roof pitch (1°–45°) • Support for all standard spring angles (38°, 45°, 52°) and custom values • Interactive visual diagrams: corner angle, miter gauge, bevel gauge, and spring angle cross-section • Complete reference table covering the entire angle range at a glance • Real-time updates as you adjust values with sliders or direct input • PDF export — save and share your saw settings, take them to the job • Clean, intuitive interface designed for quick use on site TWO CUTTING METHODS EXPLAINED: 1. Non-Compound (Vertically Nested) — molding positioned in the saw as it sits on the wall 2. Compound (Flat Down) — molding flat on the saw table with calculated miter and bevel angles WHY PROFESSIONALS TRUST THIS APP: Crown molding is one of the trickiest finish carpentry tasks. Walls are rarely perfectly square, and standard 45° cuts only work on perfect 90° corners. This calculator handles real-world angles — saving you time, material, and frustration on every job. No internet required. No ads. No subscriptions. Buy once, use forever. PERFECT FOR: • Finish carpenters and trim installers • General contractors and remodelers • Woodworkers and cabinetmakers • Homeowners doing their own crown molding • Anyone working with compound miter saws Stop wasting material on test cuts. Get it right the first time.

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.
