Squid vs AstroSol

The weather routing app trusted by the world's top offshore sailors. Squid is the mobile version of SquidX — the routing solution used by elite teams in the Vendée Globe, Route du Rhum, Transat Jacques Vabre, The Ocean Race, and more. Now that same professional-grade power is in your pocket. From solo ocean racers to weekend cruisers, Squid gives every sailor access to accurate multi-model weather data and smart routing tools — rebuilt for speed, simplicity, and offshore use. A brand-new version has just launched: completely redesigned interface, major performance upgrades, and new features continuously in development. Key Features • Smart routing engine with roadbook tool • Cloud routing with multi-route comparison • Multi-model GRIB viewer: GFS, ECMWF, AROME, ARPEGE, GEM, NAM and more • Forecasts up to 10 days, 1–3 hour time steps • Meteograms for multi-model comparison (wind & pressure) • Extensive polar database (racing & cruising yachts) • Lightweight GRIBs optimized for offline use • Iridium GO!® compatible — built for low-bandwidth environments • Custom map visualizations: isolines, wind barbs, arrows, particles Weather Coverage Wind, gusts, MSLP, rainfall, cloud cover, CAPE, humidity, temperature, surface currents, swell & wind waves.

AstroSol is a precise, educational solar calculator. Enter coordinates (or use your location) to get: • True Solar Noon (hh:mm:ss) • Sunrise & Sunset (apparent, rounded to minute) • Azimuth & Elevation at the current local time • Equation of Time and Solar Declination • Local time zone and UTC offset for the place Accuracy you can trust AstroSol implements Jean Meeus–style solar algorithms in the spirit of NOAA’s public calculator. Results are rounded like NOAA (no atmospheric refraction for Az/El at current time; sunrise/sunset use an apparent solar radius/zenith of ~90.833°). Works offline No signal? You can still compute: • All solar values from coordinates • Approximate place names & time zones using an on-device gazetteer (when available). A brief online session after the first launch lets AstroSol download a compact city list for fully offline use. Thoughtful details • Decimal or DMS inputs with hemisphere toggles • Locale-aware formatting (commas/dots) • One-tap copy for every numerical result • Pull-to-refresh to recalc and re-check connectivity • Clear “About & Help” with formulas, credits, and tips Privacy No accounts. No ads. No analytics. Location is used only on-device to compute solar data and, if you ask, to set your coordinates. Credits Meeus-style solar math; NOAA rounding conventions. Offline city data derived from GeoNames (see in-app credits). Time zone resolution uses iOS frameworks when online. Not for navigation or safety-critical use.
