Spearo Go is the spearfisher's pre-dive checklist — on your wrist.
Before you load the car, just glance at your Apple Watch. Spearo Go combines real-time weather, swell height and period, tide phases, and solunar fish activity into a single 0–10 score with a clear verdict: GO, MAYBE, SKETCHY, or NO GO.
WHAT IT SCORES
• Wind speed, gusts, and direction
• Swell height and period
• Water temperature and visibility estimate
• Tide state (rising, falling, slack)
• Solunar major and minor feeding periods
• Moon phase influence on fish activity
HOW IT WORKS
Each factor is scored individually, then combined using a weighted algorithm (Weather 30%, Marine 30%, Tides 15%, Solunar 25%) tuned for spearfishing conditions. The result is one number and one word — so you spend less time checking apps and more time in the water.
FEATURES
• One-tap verdict — GO, MAYBE, SKETCHY, or NO GO
• Composite score from 0 to 10 with animated score ring
• Five detailed pages: Verdict, Conditions, Water, Tides, Fish Activity
• Save multiple dive spots and switch between them
• Background refresh every 30 minutes — always current
• Offline tide and solunar calculations — no API key needed
• Haptic feedback when conditions change
• Fully accessible with VoiceOver support
• No subscriptions, no ads, no account required
Spearo Go uses free Open-Meteo APIs for weather and marine data. Tide heights are calculated offline using M2+S2 harmonic analysis. Solunar periods use Meeus orbital math. Your location is used only to fetch conditions — never stored or shared.
