Neptune — AI Surf Coach

Forecasts, technique & journal

Free · Designed for iPhone. Not verified for macOS.

Your next surf starts with a conversation. Ask about conditions, choose from your quiver, log a session and get guidance that builds on your experience. Neptune is your AI surf coach and surf buddy. Talk about the waves you're chasing, the board you're riding, or the session you just had. Get thoughtful guidance that builds on what you share. JUST START TALKING Introduce yourself in a conversation. Tell Neptune where you surf, what you're working on and how you like to ride. Ask a question, follow up and work through the answer together. Keep the conversation going before and after your surf. YOUR WHOLE QUIVER, IN THE CONVERSATION Tell Neptune about a new board or piece of equipment and ask it to save it. Keep surfboards, prone paddleboards, foilboards, foil kits, wetsuits and accessories together. Ask which setup makes sense for the conditions and the session you have in mind. When a supported product match is available, review the specs and image before confirming it. FIND YOUR NEXT SURF Explore nearby breaks on the map and talk through your options. Ask about conditions up to seven days ahead, where forecast data is available, with swell, wind and tide context. Longer-range forecasts are a planning outlook, and Neptune can explain where the available information is limited. MAKE EACH SESSION PART OF THE STORY Tell Neptune how your surf went and ask it to add the session to your journal. Bring the good waves, missed chances and small improvements back into the conversation. See useful maps, saved equipment and relevant photos alongside the guidance. APPLE WATCH, IF YOU WANT IT Record a surf on Apple Watch, then review the session on iPhone and talk it through with Neptune. Watch recording is optional: you can log sessions and use your coach from iPhone alone. Wave counts and ride boundaries are estimates and may need correction. Live coaching is powered by OpenAI GPT-6 Astra. Your boards. Your breaks. Your next conversation.
