Seawise vs SpeedTrace

SeaWise is the voyage planning calculator app built for captains and fleet managers who make decisions based on data — not guesswork. Plan any passage with exact nautical distances, live bunker fuel prices, AI-generated sea routes, and accurate fuel burn calculations. Everything you need to budget a voyage, brief a crew, or manage a fleet — in one place. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ --- LIVE GLOBAL BUNKER PRICES Stop hunting across broker emails and outdated spreadsheets. SeaWise pulls live MGO, VLSFO, and HFO prices from major bunkering ports worldwide — Rotterdam, Singapore, Fujairah, Gibraltar, Las Palmas, Houston, Panama, Miami, and more. See the current fuel costs at your departure port, your destination, and every stop in between. Updated continuously so your budget reflects the actual market, not last week's numbers. --- ACCURATE PORT-TO-PORT DISTANCES SeaWise calculates nautical mile distances between global ports using the Haversine formula — the same method used in professional maritime navigation. Not straight-line estimates. Not road distances repurposed for sea. Real routes. Real distances. --- AI-POWERED SEA ROUTE PLANNING SeaWise generates intelligent sea routes that follow recognised shipping lanes, account for major straits and waypoints, and avoid routing you over land. Get a full waypoint-by-waypoint route for any ocean passage in seconds. Whether you're planning a Med season, a transatlantic crossing, or a Caribbean circuit — SeaWise maps it out. --- FUEL CONSUMPTION CALCULATOR Input your vessel's fuel curve — consumption rate at different engine speeds — and SeaWise calculates your total fuel burn for any voyage. See burn in litres or metric tonnes. Apply live bunker prices to get your total fuel cost in USD. Adjust speed to model the cost difference between a fast passage and an economical one. For a 50m motor yacht burning 200L/hr, the difference between 14 knots and 12 knots can mean 30–40% less fuel on a long passage. SeaWise shows you exactly what that saving is worth. --- COMPLETE VOYAGE COST ESTIMATES Combine distance, fuel burn, live market prices, and passage time into a single voyage cost report. Ideal for: • Charter budget preparation • Owner voyage approval • Fleet manager cost tracking • Captain passage planning Export your calculation as a clean summary — ready to drop into a crew brief or send to an owner. --- BUILT FOR PROFESSIONALS SeaWise is used by yacht captains, superyacht management companies, and fleet operators managing vessels from 30 to 100+ metres. 50,000+ routes calculated. 200+ global ports covered. Trusted across the Mediterranean, Caribbean, Pacific, and Atlantic circuits. --- SIMPLE, TRANSPARENT PRICING One plan. All features. No paywalls inside the app. $9.99/month or $99/year (save 17%). Cancel any time. No contracts. --- SeaWise won't navigate your vessel. But it will make sure you arrive at the right financial decision before you leave the dock. Download SeaWise and plan your next voyage with confidence.

SpeedTrace turns your iPhone into a beautiful, glanceable GPS speedometer and trip recorder. Driving, cycling, running or sailing — see your real speed in big, high-contrast digits, watch your route draw itself on the map, and keep a history of everywhere you've been. Free to download.

Everything is a one-time purchase. — TWELVE SPEEDOMETER FACES — • Classic: the original arc gauge, free forever • Horizon: snow, timber or coast scrolling past at your speed, under the sky outside right now (Pro only) • Aurora: curtains of light that shift color as you go, with not a single line on them • Chrono: an observatory watch in blued steel, with two live subdials • Minimal, Retro LCD, Analog, Neon, Vintage, Rally, Turbo and Digital Cluster • Try any locked face for 30 seconds on the road before you decide — A SKY THAT FOLLOWS THE SUN — • The whole app is colored by the sky outside — dawn, midday, dusk, night • Worked out from the sun's angle where you are, not from a clock — BIG, GLANCEABLE SPEED — • Large, high-contrast readout you can read at a glance • Switch units instantly: km/h, mph, knots or m/s • Live altitude, compass heading, session max & average speed • Honest GPS status — we never fake a confident reading on a weak signal — HUD MODE — • Mirrors your speed onto the windshield after dark • Green while you're clear, red the moment you're over the limit — LIVE ROUTE MAP — • Watch your route draw itself in real time; follow mode keeps you centered, and you can pan freely anytime — TRIP RECORDING & HISTORY — • One tap to start; keeps going with the screen off • Automatic recording (optional): driving starts a trip, parking ends it • Trips come back as postcards — your route on a map, in the sky color of the hour you drove • Every trip saved with distance, duration, max/average speed and climb • Detail view with speed and elevation charts, and a share card of your route • Export as GPX or CSV to analyze elsewhere — SPEED LIMIT & ALERTS (optional) — • Shows the posted limit for the road you're on, from OpenStreetMap • Coverage varies by road; where none is published, SpeedTrace says so instead of guessing • Gentle voice and sound alerts when you go over • Leave it off and the app uses no network at all — LIVE ACTIVITY, WIDGET & SYNC — • Keep your live speed in the Dynamic Island and on the Lock Screen • Home-screen widget, plus iCloud sync to every device you own — 0–100 ACCELERATION TIMING — • Time a standing start: 0–100 km/h or 0–60 mph, and keep every run to compare — BUILT FOR EVERY JOURNEY — • Day & night themes, six color palettes for your dial, and a keep-screen-awake option so your speed never dims away — WHAT'S FREE, WHAT'S PRO — Free: the Classic dial, all four units, the live map, unlimited trip history, trip charts, GPX/CSV export, speed limit alerts, automatic recording, share cards, Live Activity, the widget and iCloud sync. SpeedTrace Pro is a single one-time purchase that unlocks every paid dial — including Horizon, which is sold no other way, and every dial added in future at no extra cost — along with HUD mode, 0–100 timing, the color palettes and the alternate app icons. Individual dials can also be bought on their own. — PRIVACY FIRST — No servers, no accounts. Your trips, routes and speed history live only on your device and in your own iCloud. We don't collect analytics, we don't track you, and we never sell your data. The optional Speed Limit feature is the only thing that touches the network — and only when you turn it on. — QUESTIONS? WE ANSWER — Something not working, or a feature you wish existed? Email support@mzjpg.com — a real person reads every message and replies, usually within a day. And if SpeedTrace has earned its place on your home screen, a review means a lot to an independent developer. Note: Continued use of GPS running in the background can dramatically decrease battery life. SpeedTrace uses background location only while recording a trip.
