Cobalt Weather

Cobalt is a fast, uncluttered weather app that takes its color from the conditions and puts your own backyard readings right next to the forecast. Open it on a clear afternoon and it is warm and bright. Open it in a thunderstorm and the whole interface shifts. Every screen, chart, and detail sheet is colored by the weather it is describing, in both light and dark mode. FORECASTS • Hour-by-hour and 10-day forecasts, with separate daytime and overnight conditions for every day • Minute-by-minute rain for the next hour where available, so you know when it starts and when it stops • Interactive charts for precipitation, temperature, wind, and atmosphere • Feels like, humidity, dew point, UV index, visibility, cloud cover, pressure, and air quality • Sunrise, sunset, daylight remaining, moonrise, moonset, and moon phase • Tap any day or any hour for a full detail sheet, colored by that day's own forecast SEVERE WEATHER • Official watches, warnings, and advisories, pinned above the forecast • Color-coded by severity, with the exact window each one covers YOUR OWN STATION • Connect an Ambient Weather, Ecowitt, Davis, or Tempest station in a couple of minutes • Live temperature, humidity, wind speed, gusts, direction, rain, and pressure • Rain totals by rate, day, week, month, year, and current event • Station screens take their color from your own sensors, not the regional forecast MADE TO BE YOURS • Save your places and your station, and switch between them with a tap • Jump to your current location instantly • Hide any reading or card you don't need on the forecast page • A forecast widget on your home screen that stays current without opening the app • Pick your own units • Follow your system theme or lock it to light or dark • Made for iPhone Duo and iPad: fills every screen, open or closed COBALT PLUS Cobalt is free, with no account and no sign-in. Cobalt Plus is an optional subscription that adds: • Alerts on your phone: severe weather at up to three saved places, rain about to start, a daily briefing, and limits you set on your own station's readings • History: chart any reading from one saved place and up to two stations over the last day, week, month, or year • Your station compared with the forecast, reading by reading, and how the forecast has changed since yesterday • Up to 10 saved places and as many stations as you like (Free includes 2 places and 1 station) • Every extra sensor your station has, from extra temperature and humidity channels to soil, leaf, air quality, lightning, and leak sensors, each one renamable, like Kitchen or Garden • Station widgets and a full forecast widget, refreshed every 30 minutes PRIVACY Cobalt has no accounts and no sign-in. Your station credentials are stored in your device's Keychain and are sent only to fetch your own readings. Location is used only to show you the weather where you are. SOMETHING WRONG? Cobalt is made by one person, and I would genuinely rather hear about a problem than have you put up with it. Tell me what happened and what phone you're on: Nick@NickSaulino.com.

Verdict
The clearest difference is in-app purchases: StormCast at none against Cobalt Weather's 2. StormCast also leads on iOS requirement (15.0 vs 17.0). Cobalt Weather's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
