Boat Buddy — boat GPS, tides, and fishing logbook.
Plan the tide, track your GPS route, mark fishing spots, monitor anchor drift, and keep a private boat logbook that stays useful when signal gets thin.
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.
Plan around the tide
Add nearby NOAA stations, check the next high and low, and set tide reminders before launch.
Track the route
Record speed, distance, course, duration, and route points while the trip is active.
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.
