Zasder Weather vs MeteoBlend

Zasder Weather is a clean, fast app for personal weather stations on iPhone, Apple Watch and Mac. One purchase, every platform. It is bring-your-own backend: point it at your own server, and your station's data is yours, end to end. No ads, no tracking, no subscriptions. WORKS WITH YOUR STATION • AmbientWeather, Davis WeatherLink, WeatherFlow Tempest and Ecowitt from their clouds, an Ecowitt gateway posting straight to your server, or a WeatherLink Live read on your network for two-second freshness. • Direct radio capture: a $20 LilyGO board decodes AcuRite Atlas or Fine Offset, Ecowitt and Ambient sensors off the air. • AirGradient and Govee air monitors with CO2 and PM2.5, and soil probes on up to eight channels. • No server yet? The Mac app builds one on your Fly.io account in a minute, or run the backend in Docker. THE DASHBOARD • Live conditions, a 24-hour curve, today's highlights ranked against your own record, the moments the weather changed, and a strip that says hour by hour whether each source was healthy. • Arrange every screen: drag the cards into your order, hide what you do not need, and do the same for Charts. • A 7-day forecast with a written narrative, tap a day for its full text, and a scorecard of how right the forecast has been at your station. • Charts with a wind rose, station comparison, and drag to inspect. Explore any past day. Records in under a second. Insights, a year heatmap and a Science page of derived numbers. ALERTS THAT ARRIVE • Thresholds on any field, evaluated on your server, by push and email even when the app is closed. • Weather watches with no setup: lightning nearby with an all clear, frost, heat, a fast pressure drop, a gust front, the first frost, low batteries and a sensor gone quiet. • Severe weather from the National Weather Service, one family at a time: mute floods and keep tornadoes, with a warning that sounds different from a watch. • Storm summaries after the rain ends: total, peak rate, temperature drop and top gust, as a push, an email card or both. • Live Activities on your Lock Screen for the rain countdown, a storm in progress, lightning nearby, a wind ramp, a freeze night and a heat day, and they reach the Apple Watch Smart Stack. • Quiet hours, a morning report and an evening outlook at the minute you choose, sky notes before sunset, and report emails in the look you pick. SHARE IT • Read only links for family with one tap setup, and Sites to keep every server you are given beside your own. • Your station on the shared map at maps.zasder.com with the location rounded as much as you like. • Send your readings to Weather Underground, PWSweather, Windy, Weathercloud, CWOP, Met Office WOW, AWEKAS and OpenWeatherMap. • Story cards from your own record, a public dashboard page to embed on your site, NOAA-style reports, and an AI assistant connected to your server. ON YOUR WRIST AND HOME SCREEN • Apple Watch app with configurable complications and a Big complication per reading. • Home Screen and Lock Screen widgets, editable per widget, a dashboard widget the size of a page, and a widget that follows the station you choose. • Siri: ask for any reading, the forecast, rain totals or records, in your units. Your stations appear in Spotlight. YOUR DATA, YOUR RULES • Bring years of history from Weather Underground, a WeeWX database, or any CSV, and export every reading to CSV. • Calibrate any sensor with an offset or a scale, typed in your units. • Units: °F or °C, mph, km/h, knots, m/s or Beaufort, in or mm, inHg or hPa. Light, dark, or automatic. Dynamic Type throughout. • Settings backed up to iCloud, the server's database backed up from the app, one-tap server updates. The backend is open source (MIT): https://github.com/volneydouglas/zasder-weather-backend Data goes only to your server and what you opt into. Optional tip jar via In-App Purchase, purely cosmetic; nothing is paywalled. Requires iOS 18.
