Introducing Neptune: Your AI Surf Coach Is Here

Surfing Just Got Smarter

We've all been there. You check three different forecast apps, text your buddies to see who's going out, show up at the beach hoping the conditions match what you saw online, and paddle out without a real plan for what to work on. You might have a great session, but you forget half of it by the time you're toweling off.

What if you had a coach who knew your ability level, your schedule, your local breaks, and your goals — and was available 24/7 to help you make the most of every session?

That's Neptune. And today, we're officially launching V1.

What Is Neptune?

Neptune is an AI surf coaching app for iPhone and Apple Watch. It combines real-time surf forecasts, GPS session tracking, and a conversational AI coach that actually learns who you are as a surfer. It's not a generic chatbot bolted onto a forecast app — it's a coaching system built from the ground up around your surfing.

Here's what you get in V1:

Your Personal AI Surf Coach

Neptune's coach isn't a one-size-fits-all tips engine. It's a conversational AI that builds a persistent memory of your surfing — your experience level, what techniques you're working on, your preferred spots, your board quiver, even your weekly schedule and any injuries you're working around.

Ask it anything. "What should I focus on today?" "Why do I keep bogging my bottom turns?" "Is it worth paddling out right now?" The answers are tailored to you because Neptune actually knows you.

The more you use it, the better it gets. Neptune extracts insights from every conversation — your progression, your preferences, your weak spots — and uses them to give increasingly specific coaching. It's like having a surf coach in your pocket who remembers every session you've ever talked about.

The Game Plan: Know Before You Go

Every time you open Neptune, you get a Game Plan — a personalized daily briefing that combines live conditions at your local spots with coaching recommendations. It tells you which board to grab, what to work on, and whether it's even worth suiting up.

No more bouncing between Surfline, Windy, and your group chat. Neptune pulls together swell, wind, tide, and weather data — everything you'd normally piece together when reading a surf forecast — and filters it through what it knows about your ability and goals.

GPS Session Tracking

Log your sessions with detailed GPS wave tracking. Neptune records your waves, maps your tracks, and gives you a visual record of every session.

After each session, you can review your waves, note what worked, and chat with your coach about what to improve next time. Over time, you build a complete surf tape — a visual history of your progression.

Apple Watch Integration

Start and track sessions directly from your wrist. Neptune's Watch app uses HealthKit workout tracking to stay alive in the background, recording GPS data and detecting your waves while you surf.

No phone in your pocket. No missing data. Just tap start on your watch, go surf, and everything syncs to your iPhone when you're done.

Smart Spot Discovery

Neptune knows the breaks. Browse local spots with real-time conditions, and let Neptune tell you which spot is firing for your skill level today. Neptune's Pick highlights the best option based on current conditions and what you're working on.

Crew: Surf With Your People

Surfing is better with friends. Neptune's Crew features let you see who's paddling out, coordinate sessions, and share plans. See live sessions from your crew, plan future sessions together, and keep your surf community connected.

Your Surfer Profile

Track your progression over time with a detailed surfer profile. Manage your quiver, review your session history, set goals, and see your stats evolve as you improve.

Neptune's Memory

This is what makes Neptune different from every other surf app. Neptune remembers. Your coach builds a persistent understanding of who you are — your schedule, your preferences, your injuries, your goals, your progression. You can view and manage everything Neptune knows about you at any time.

It's not a black box. You're in control of your data, and you can add, edit, or remove anything. But the magic is that you don't have to repeat yourself. Tell Neptune once that you surf before work on Tuesdays and Thursdays, and it'll factor that into every recommendation going forward.

Built for Surfers Who Want to Get Better

Neptune isn't for everyone. It's not a social media app. It's not a forecast aggregator with a chatbot stapled on. It's a coaching tool for surfers who are serious about improving — whether you're a beginner trying to stand up consistently or an intermediate surfer working on generating speed down the line. If you're looking for a framework to accelerate your progression, we've also written about the five habits of surfers who improve fast.

If you've ever wished you could afford a personal surf coach, Neptune is the next best thing. And in some ways, it's better — because it's available every single day, it never forgets what you're working on, and it's always checking the conditions for you.
