Boat Buddy: Boat GPS Logbook

Navigation · Sports · Built by QnSub Tech · iPhone

Made for quick use on the water

Boat Buddy combines the core tools boaters and anglers reach for before, during, and after a trip.

Boat GPS Cockpit

Start a trip and see speed, heading, distance, timer, GPS quality, and a route breadcrumb trail from one readable map screen.

Tide Planner

Search NOAA tide stations, save favorites, view high/low tide cards, scrub a 24-hour graph, and keep a 7-day tide cache offline.

Fishing Logbook

Save catches with species, bait, lure, photo, notes, GPS spot, water type, and tide context in a private on-device logbook.

Waypoints and Spots

Mark ramps, marinas, hazards, anchor points, lake spots, harbors, and favorite fishing locations while you are underway.

Anchor Watch

Set an anchor radius during active trips and get a local alert if your boat drifts outside the safe zone.

Boat Readiness

Keep a boat profile, categorized launch checklist, maintenance records, service reminders, unit preferences, and demo mode for dry-land testing.

Before, during, and after every trip

A calm workflow for planning, recording, and reviewing time on lakes, harbors, marinas, and coastal waters.

01

Plan around the tide

Add nearby NOAA stations, check the next high and low, and set tide reminders before launch.

02

Track the route

Record speed, distance, course, duration, and route points while the trip is active.

03

Log the story

Save catches, spots, notes, maintenance, and exports so the trip is easy to review later.

Private by default. Safety-aware by design.

No accounts, no ads, no analytics SDKs, and no QnSub server collecting your trips. Boat Buddy is a planning and logbook companion, not a certified navigation instrument.

Your trips, track points, catches, waypoints, boat records, photos, and settings are stored locally on your device with SwiftData and UserDefaults. NOAA tide requests and Apple Maps are used only for the features that need them.

Launching soon.

Boat Buddy is built by QnSub Tech for everyday boaters, lake anglers, kayakers, marina users, and coastal fishers.
