## What is Spearo Go?

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.


## Version history (last 2 releases)

### 1.1.0 (3) — 2026-09-02

Tides are now sourced from NOAA tide stations in US waters and from WorldTides gauges elsewhere, and the app tells you which station a reading came from. Where a spot has no tide or sea data at all, it now says so instead of estimating.

 Also in this release:

 • Save dive spots anywhere — search for a place by name and switch between your spots, instead of only getting conditions where you are standing
• Larger, clearer text throughout, and it now follows your watch's text size
 • A new Today screen — air temperature, conditions, high and low, rain, and sunrise and sunset
 • Corrected sunrise, sunset and moon times, which could be hours out
 • Sea temperature and swell are no longer guessed where there is no data
 • The verdict screen is redesigned, and says which readings it could not include

### 1.0 — 2026-04-10

No release notes.
