Record every sail
One tap starts a track. Background GPS keeps logging with the phone locked, with live speed, heading, distance, and a Lock Screen view while under way.
Anchor alarm
Pin your anchor, set rode and margin, and sleep. If the boat drags, a looping siren, notifications, and a full-screen alert make sure you know, with live drift on the Lock Screen.
Nautical charts
OpenSeaMap seamarks and modeled depths over Apple Maps, with offline tile caching for the areas you sail.
Plan, then sail
Tap a route on the chart, see distance and ETA, schedule it with your crew, then start it: live course-to-steer guidance keeps you honest.
Share cards
Strava-style trip cards from your photos, or your videos, with the route, stats, and crew overlaid. Square, postcard, or story format.
The whole boat
Boats, crew, maintenance with engine hours, GPX import, and onboard storage mapped on your boat's own layout so everyone finds the spare impeller.
Private by design
No accounts, no analytics, no servers. Everything lives on your device, synced privately between your own devices with iCloud. Your tracks are nobody's business but yours. Read the privacy policy.
