Why Spearo Go?
Built by spearos, for spearos. Every feature earns its place.
One Tap. One Answer.
No scrolling through 5 weather apps. Spearo Go combines weather, marine, tide, and solunar data into a single composite score and a clear verdict: GO, MAYBE, SKETCHY, or NO GO.
Weather Conditions
Real-time temperature, wind speed, gusts, cloud cover, and precipitation. Weighted at 30% of your overall score because conditions on the surface matter before you get in.
Marine Data
Swell height, swell period, wind waves, and water temperature. Weighted at 30% because what's happening underwater is what makes or breaks your dive.
Tide Windows
Current tide direction, next high and low times, and optimal dive windows. Weighted at 15% — incoming tides often mean better visibility and more active fish.
Solunar Fish Activity
Major and minor solunar periods, moon phase, and predicted fish activity levels. Weighted at 25% because timing your dive with peak activity puts more fish on your stringer.
Your Spots, Your Watch
Save your favorite dive spots and check conditions for any of them right from your wrist. 30-minute background refresh keeps data current throughout the day.

Frequently Asked Questions
Do I need my phone with me?
No. Spearo Go runs standalone on Apple Watch (with cellular or WiFi) and Wear OS. Once you've saved your spots, it fetches data directly from your watch.
How is the score calculated?
The 0–10 composite score combines Weather (30%), Marine (30%), Tides (15%), and Solunar (25%). Each factor is scored independently and weighted to give you the most accurate dive-day prediction.
What do the verdicts mean?
GO (8–10): Excellent conditions, get in the water. MAYBE (5–7): Decent but check details. SKETCHY (3–4): Conditions are marginal, proceed with caution. NO GO (0–2): Stay home, conditions aren't worth it.
Is this available on Android / Wear OS?
Spearo Go is live on Apple Watch and currently in review for Google Play / Wear OS. It's coming soon to Android watches.
