Listing changes AppTracker has observed for this app in this storefront — new versions, price moves, rating shifts, and store copy.

Sep 2, 2026
New version 1.0 → 1.1.0 (3)

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

About

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.
