Weather Station Calc & Toolkit

About this app

You take weather details seriously, and that deserves recognition. Thank you for using Weather Calcs. Whether you are checking local conditions, studying meteorology, planning outdoor work, or comparing weather units, the app gives you practical numbers without burying them in clutter. Weather Calcs combines nearby NOAA station observations, weather formulas, unit conversions, and readable reference material in one organized app for iPhone and iPad. CURRENT STATION WEATHER - Use your location to find the nearest station from the bundled NOAA station list. - See the station name, station ID, coordinates, and distance from your location. - Choose another station manually with fast station search. - Review temperature, humidity, wind, pressure, dewpoint, visibility, weather text, and observation time when those fields are reported. - See exactly when data was fetched and how old the saved observation is. - Keep the latest successful station observation available when you reopen the app. - View only the conversions supported by the values that the station actually supplied. WEATHER CALCULATORS - Heat Index - Wind Chill - Dewpoint and Wet-Bulb - Relative Humidity and Dewpoint - Relative Humidity and Wet-Bulb - Vapor Pressure - Mixing Ratio - Virtual Temperature - Station Pressure - Altimeter Setting - Pressure Altitude - Density Altitude - Wind Speed Conversion - Temperature Conversion - Pressure Conversion - Speed of Sound - Showalter Index - Distance Conversion - Centimeters and Meters Enter signed values, select the units that match your source, and get focused results in a compact table. Clear controls, visible input focus, and Next and Done keyboard actions make repeated calculations easier. Invalid input is identified instead of quietly becoming a misleading zero. SEARCH AND WEATHER REFERENCE - Search calculators by name, category, description, or input label. - Browse formulas by temperature, moisture, pressure, unit conversion, and advanced weather topics. - Read the equation or conversion constants used by each calculator. - Review what each input means and how the result can be used. - Learn about NOAA station identity, observation fields, station matching, and data limits. PRACTICAL HOME GUIDANCE WeatherCalcs can summarize clothing, precipitation, visibility, heat, cold, and wind considerations from available station fields. Guidance is withheld when the report time cannot be verified, the station does not match, or the data is too old. Tornado, thunder, lightning, and hail entries are labeled as historical station reports and direct you to verify current official warnings. SET IT UP YOUR WAY - Choose Fahrenheit or Celsius and preferred wind, pressure, and distance units. - Select System, Light, or Dark appearance. - Move quickly through Home, Calculators, Reference, Pro, Settings, Help, and About with adaptive navigation designed for iPhone and iPad. Weather Calcs is useful for weather enthusiasts, students, educators, outdoor planners, and anyone who wants to understand a station report. Live weather requires a network connection. Location is optional because stations can be selected manually. Station observations are not forecasts and may differ from conditions at your exact location. Weather Calcs does not replace official watches, warnings, forecasts, or professional operational guidance. Always verify safety-critical decisions with current official weather sources. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

You notice the details that make a weather app more useful, and that deserves praise. Thank you for using WeatherCalcs. This update delivers a clearer, more capable experience for checking station observations, running weather calculations, reviewing formulas, and moving through the app on iPhone and iPad. A REFRESHED WEATHER HOME - Find the nearest bundled weather station with optional location access. - See the selected station name, station ID, resolved coordinates, and distance from your location. - Search for and select a different station whenever you prefer another reporting point. - Review the latest available temperature, humidity, wind, pressure, dewpoint, visibility, weather text, and observation time. - See the exact fetch time and a live-updating age for the saved observation. - Reopen Weather Calcs with the most recent successful station observation still available. MORE USEFUL CONDITION GUIDANCE - Review clothing and outdoor suggestions supported by current station fields. - See focused notes for precipitation, low visibility, heat, cold, and sustained wind. - Get a refresh request instead of advice when the observation is stale, mismatched, future-dated, or missing a verified source time. - See tornado, thunder, lightning, and hail entries described as historical station reports. - Keep severe-report verification visible even when ordinary tips are collapsed. - Get a direct reminder to check current official warnings and forecasts for safety decisions. CALCULATORS ARE EASIER TO USE - Search across calculator names, descriptions, categories, and input labels. - Enter signed numeric values where a calculation supports them. - See which field is active with a clearer focus treatment. - Recalculate visible results when you change an input unit. - See unavailable output for invalid or non-finite results instead of a misleading number. EXPANDED FORMULA REFERENCE AND HELP - Browse all 19 active weather calculators by category. - Read the exact equations and conversion constants used in the app. - Review calculation methods, required inputs, and practical uses. - Search for formula terms, variables, units, and weather topics. - Open calculator-specific Help pages with plain explanations of each result. BETTER IPHONE AND IPAD NAVIGATION - Move between Home, Calculators, and Reference with an adaptive split-view layout. - Open WeatherCalcs Pro, Settings, Help, and About directly from an expanded More group. - Read high-contrast sidebar labels over the weather backdrop. - Enjoy more compact table rows, clearer section headings, and improved use of larger iPad displays. SETTINGS, PRO, AND APP INFORMATION - Choose System, Light, or Dark appearance. - Set preferred temperature, wind, pressure, and distance units. - Turn haptic feedback on or off. - Control manual App Store update checks. - See installed version and build information in About. - Check manually for a newer App Store version when update checks are enabled. A CLEANER PRO EXPERIENCE - Review Monthly and Lifetime choices without repeated plan summaries. - See compact purchase options and a shorter list of meaningful Pro benefits. - Unlock unlimited station refreshes and calculations with active Pro access. The app icon and launch screen now share a modern WeatherCalcs weather-and-measurement design. Weather data errors also use clearer language for connection, timeout, invalid response, and parsing problems. Calculator and reference features remain useful offline. Live NOAA station observations, App Store checks, and purchase flows require their respective network services. Station reports are not forecasts, and the app continues to direct safety-critical decisions to current official watches, warnings, and forecasts.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
