Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Carrot Weather
- Most advanced weather data sources (AccuWeather, The Weather Channel, Aeris Weather, Netatmo personal stations) and map layers (lightning, alerts, wind, humidity, dew point, snow depth) are locked behind paid Premium/Ultrapremium Club subscriptions, not included in the base app
- Background Apple Watch updates for premium data sources require an active subscription
- Pricing for named tiers (Premium Club, Premium Ultra, Premium Family) is disclosed only via in-app purchase screens rather than a public pricing page with fixed dollar figures
- Mac App Store listing shows a separate $14.99 one-time purchase price for macOS, a different pricing model than the free-to-download iOS/Android version
Sea Machines
- Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
- Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
- Pricing is not published and is arranged directly with the vendor
- The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
