Baltic Water

Is the water warm enough today? Baltic Water tells you in a second. Live sea temperature for 124 cities and coastal towns around the Baltic, from Saint Petersburg to Copenhagen. Every number is an average of seven independent sources, so one offline buoy or one cloudy satellite pass never gives you a wrong answer. SEVEN SOURCES, ONE HONEST NUMBER Open-Meteo Marine's ocean model, three satellite analyses (NASA JPL MUR SST, NOAA OISST and NOAA Geo-Polar Blended) and coastal observation networks from Sweden (SMHI), Finland (FMI) and Poland (IMGW-PIB). See exactly which sources are reporting right now, with the station name and distance for every coastal reading. Nothing is hidden behind a single figure. WHERE THE WATER HAS BEEN, AND WHERE IT'S GOING Every city has a 30-day history with a min-max range across sources and a 10-day forecast, so you can plan the swim, not just guess it. FIND YOUR BEACH Up to three popular beaches per city, with real photographs, GPS coordinates, the distance from the city centre and one tap to open in Maps. YOUR FAVORITES Save the places you swim most. A dedicated tab shows their temperature, 7-day trend and forecast side by side, and ranks them warmest to coolest. THE WHOLE COAST, ONE MAP 124 cities across nine countries: Russia, Sweden, Finland, Denmark, Germany, Poland, Lithuania, Latvia and Estonia. Search by name or just tap the map. MADE FOR iPHONE DUO On the foldable iPhone Duo, Baltic Water uses both screens: the map and city details sit side by side when unfolded, and the interface turns a page like a book as you fold and unfold the device. NINE LANGUAGES English, Russian, German, Polish, Lithuanian, Latvian, Finnish, Swedish and Dutch. Interface, city and beach names are all translated. Switch from any screen with one tap. SMALL DETAILS A water drop falls from the Dynamic Island when the app opens. The home-screen icon can shift between a cold, classic or warm look depending on the Baltic-wide average temperature, and it comes in light, dark and tinted versions for every iOS appearance. No ads. No tracking. No account. Every reading is public data, and every city page shows exactly where it comes from. Enjoying the app? An entirely optional tip jar sits in Settings & About. The app is exactly as complete without it.

Verdict

The call

The clearest difference is in-app purchases: Robben.App Pro at none against Baltic Water's 6. Robben.App Pro also leads on iOS requirement (16.4 vs 18.6). Baltic Water's advantage is update cadence (every 2 months vs every 5 months). On price, ads and device support there is nothing between them.
