Store description excerpt
Sailing Log is the logbook your boat deserves: it records every sail automatically, keeps watch while you sleep at anchor, and turns your trips into something worth sharing. No accounts, no subscriptions, no servers — your data lives on your devices and nowhere else. RECORD EVERY SAIL Tap once and go. GPS keeps logging with the phone locked and pocketed, tracking distance, speed over ground, heading, and duration. A Lock Screen view shows your numbers without unlocking. ANCHOR ALARM THAT ACTUALLY WAKES YOU Drop the hook, set your rode and margin, and sleep. If the boat drags, a looping siren, repeating notifications, and a full-screen alert make sure you know — with live drift distance on the Lock Screen all night. NAUTICAL CHARTS OpenSeaMap seamarks and modeled depths over Apple Maps, with offline tile caching for the waters you sail. Tap any charted light or buoy to see its details. Over 23,000 marinas worldwide. PLAN, THEN SAIL Draw a route on the chart, see distance and ETA instantly, set the date and crew, then start it — with live course-to-steer guidance keeping you on track. SHARE CARDS WORTH POSTING Turn a trip into a Strava-style card from your photos or videos, route and stats overlaid, in square, postcard, or story format for Instagram and TikTok. THE WHOLE BOAT Boats with full details, crew rosters, maintenance with engine hours, GPX import and export, and onboard storage mapped on your boat's own interior layout so everyone finds the spare impeller. PRIVATE BY DESIGN No analytics, no tracking, no advertising. Everything syncs privately between your own devices via iCloud, and exports as standard GPX whenever you like. Your logs are yours. The first 10 trips are free. Unlimited trips is a single one-time purchase — no subscription, ever. IMPORTANT — Sailing Log is for reference and general guidance only. Charts, depths, and marina data come from OpenSeaMap, EMODnet, and OpenStreetMap; they are incomplete and may be inaccurate, and must not be used for navigation or routing. The anchor alarm is a backup aid that can fail (GPS, battery, or iOS issues) and is no substitute for a proper watch. Always navigate with official charts, keep a lookout, and use your own judgment. You are solely responsible for the safety of your vessel and crew; the developer accepts no liability.
