Description

Zasder Weather is a fast, private iOS app for personal weather stations.

Bring your own backend by connecting the app to your server. Your station data remains yours from end to end. No ads, tracking, or subscriptions.

SUPPORTED WEATHER SOURCES

Ambient Weather: Your backend polls the Ambient Weather REST API and stores historical data in SQLite.

Davis WeatherLink: Use cloud polling or run a small LAN poller next to a WeatherLink Live for updates approximately every two seconds.

Direct RF capture: Use an affordable LilyGO ESP32 board to receive AcuRite Atlas sensors on 433 MHz or Fine Offset, Ecowitt, and Ambient sensors on 915 MHz. Optional discovery mode supports La Crosse, Oregon Scientific, AcuRite 5-in-1 and tower sensors, Auriol, TFA, and approximately 180 other station types. No vendor cloud is required.

FEATURES

Multi-station dashboard: View every station on one screen, including current conditions, feels-like temperature, a 24-hour temperature graph, a day and night sun dial, humidity, pressure, wind, rain, dew point, and UV.

Historical data and insights: Browse past observations, compare stations, review records, and explore statistics calculated from your own weather data.

Detailed charts: Explore temperature, feels-like temperature, humidity, wind, pressure, dew point, solar radiation, and rainfall across periods ranging from one hour to seven days. Tap and drag to inspect individual readings. A 16-sector wind rose is also included.

Custom alerts: Create thresholds for any field and apply them to one station or every station. Alerts are evaluated by your backend, so email and push notifications can arrive even when the app is closed.

Apple Watch app: Check current temperature, daily highs and lows, a 24-hour chart, feels-like temperature, humidity, and UV from your wrist. It also works over LTE without your iPhone nearby.

Watch face complications: Display temperature, feels-like temperature, dew point, humidity, wind, UV index, or today’s rainfall in corner, circular, rectangular, and inline complication slots.

Home Screen widgets: View current station conditions, temperature, feels-like temperature, wind, gusts, rainfall, humidity, and pressure.

Flexible units: Choose Fahrenheit or Celsius, mph, km/h, knots, m/s, or Beaufort, inches or millimeters, and inHg or hPa.

Weather forecast: View a free seven-day forecast from Open-Meteo with no API key required.
