New: the Right of Way Emulator. Build any situation on the water and see who gives way, what to do, and which horn signal to sound — with the rule behind it.
Leave the dock with a clear head.
If you've ever driven home wondering whether you left a hatch open or a battery switch on, HelmKeeper is for you. It's the clean, premium app that handles the hundred little things every boater juggles — so the only thing on your mind is the water ahead.
DISTRACTION-FREE & AD-FREE When you are at the helm, you need critical tools—not intrusive pop-ups or clunky banner ads. HelmKeeper delivers a 100% premium, distraction-free experience designed with strict battery and data discipline. We use one-shot locations and smart caching so your phone still has charge left at the end of a long day out.
PRE-DEPARTURE & CLOSE-UP CHECKLISTS Build a checklist for each of your boats and tap through it every time. Switches off, hatches shut, seacocks closed. You can even select checklist items and text a "what to bring" list directly to your crew so they arrive at the dock prepared.
ONE-TAP FLOAT PLANS Filing a float plan is a vital safety practice that is often skipped because it is too tedious. HelmKeeper makes it instant. Select your trip, pick an emergency contact straight from your phone, and text your intentions in a couple of taps. Simple to send, reassuring to have.
HONEST, CAPABILITY-AWARE CONDITIONS Stop guessing where your data comes from. HelmKeeper maps over 4,000 NOAA stations and shows you exactly what each one offers:
- Clear Badges: See exactly what each station tracks - tide, current, buoy (wind & waves), or weather.
- Honest distance labels: when the nearest data is farther off (e.g., "Nearest wave data: 3.2 miles away").
- Pinpoint Weather: NWS watches, warnings, and forecasts pulled precisely for your GPS location.
EMERGENCY PROCEDURES, READ BEFORE YOU NEED THEM (WORKS OFFLINE) Step-by-step write-ups worth going through at the dock, and still there when you have no cell signal. Includes real-world scenarios missing from standard apps:
- Prop Strikes & Prop Entanglement
- Running Aground & Capsizing
- Man Overboard (MOB)
- Fire Aboard & Taking on Water
- Engine or Steering Failure
- Medical Emergencies
EVERYTHING IN ONE PLACE
- Manage Vessels: Track multiple boats—whether you are managing a 27-foot classic cruiser or stepping up to an offshore dual console—and securely store your insurance policy info.
- Quick-Reference Articles: Access essential guidance covering engine maintenance, navigation, anchoring, and docking.
- Saved Locations: Keep your favorite spots and ramps handy.
PRIVATE & SECURE Sign in with Apple. Your data is yours. We do not monetize your location or tracking history, and you can permanently delete your account and all its data anytime. Zero ads, ever.
IMPORTANT SAFETY NOTE HelmKeeper is an informational and organizational tool — not a substitute for proper seamanship, official charts, official forecasts, or emergency services. In an emergency on the water, contact the U.S. Coast Guard on VHF Channel 16 or call 911.
Built by an everyday boater, for everyday boaters. Welcome aboard.

Right of Way Emulator — new, in Help.
Build a situation: put a vessel anywhere around you, choose what it is and which way it's pointing, and see who gives way, what to do, and which horn signal to sound. Or test yourself on ten situations drawn from a bank of thirty — half of them the ones that catch experienced boaters out.
Every answer cites its rule and explains why the other three options are wrong. Tap any rule number for a plain-language summary, including where the Inland and International rules differ. Works with no signal.
Also new
- Horn signals reference: what one, two, three and five blasts mean, and why the same horn means something different inland than it does offshore.
- Help is now a set of cards you drill into, with search on the front page.
