## What is Zasder Weather?

Zasder Weather is a clean, fast app for personal weather stations available on iPhone, Apple Watch, and Mac.

One Universal Purchase includes every platform.

Bring your own backend, connect the app, and choose where your station history is stored. Your weather data remains under your control, without vendor lock-in.

No ads. No tracking. No subscriptions.

WORKS WITH YOUR STATION

• AMBIENT WEATHER
Retrieve station data from the Ambient Weather Network cloud.

• DAVIS WEATHERLINK
Use cloud polling or run a lightweight LAN poller alongside a WeatherLink Live for updates approximately every two seconds.
• WEATHERFLOW TEMPEST
Connect using a free personal access token, including support for lightning strike data.
• DIRECT RF CAPTURE
A LilyGO board costing approximately $20 can decode AcuRite Atlas sensors on 433 MHz or Fine Offset, Ecowitt, and Ambient Weather sensors on 915 MHz—directly from the air.

Optional discovery mode also supports La Crosse, Oregon Scientific, and approximately 180 other station types, with no vendor cloud required.

Cloud integrations can be configured directly from Settings → Integrations, with no manual server configuration required.

POWERFUL WEATHER FEATURES

• INSTANT RECORDS
Monthly, yearly, and all-time highs and lows load in under a second—even with years of station history.

• LIGHTNING TRACKING
Stations with a lightning detector get a live strike tile, detailed charts, and a “Most Strikes in an Hour” record.

• STORM SUMMARIES
After the rain ends, receive one notification showing total rainfall, peak rain rate, temperature drop, and top wind gust.

• SHARE YOUR WEATHER
Create read-only links for family and friends. One tap configures their app. Name each link, see who has access, and revoke access individually.

• QUICK SETUP
Configure a new device with one pasted code or tapped setup link. No more manually copying URLs and access tokens.

• CUSTOM ALERTS
Create thresholds for any weather reading. Alerts are evaluated by your backend, allowing email and push notifications to arrive even when the app is closed.

• DETAILED INSIGHTS
Explore daily statistics, heat and cold ledgers, gaps between rain events, and a yearly weather heat map calculated by your server.

• COMPLETE HISTORY
Explore any day in your station history, import years of previous observations from Weather Underground, or forward live readings to Weather Underground.

• INTERACTIVE CHARTS
View nine weather readings across periods ranging from one hour to seven days. Drag to inspect any point and explore wind direction with a 16-sector wind rose.

• APPLE WATCH APP
View your stations from your wrist with configurable complications for temperature, feels-like temperature, wind, UV index, and more.

• HOME SCREEN AND LOCK SCREEN WIDGETS
See your station’s current conditions at a glance. Each widget can be edited to display the readings you choose.

• ONE-TAP SERVER UPDATES
See your backend version in Settings and install updates with one tap—or enable automatic updates and never think about it again.

• ACCESSIBLE TEXT
Text scales throughout the app using your preferred Dynamic Type setting.

• FLEXIBLE APPEARANCE
Choose light, dark, or automatic appearance. Back up your settings and restore them on another device.

• CUSTOMIZABLE UNITS
Choose °F or °C; mph, km/h, knots, m/s, or Beaufort; inches or millimeters; and inHg or hPa.

• SEVEN-DAY FORECAST
View a seven-day forecast with a written daily weather summary.

OPEN-SOURCE BACKEND

## Version history (last 5 releases)

### 2.1 — 2026-09-08

Reports, Explore, and your own weather in Claude or ChatGPT.

• Reports: your morning report and every storm summary are kept, so you can open them again. A Reports pane in History lists them newest first, and you can run a classic monthly or yearly climate report for any station in the NOAA style, with extremes, rain and degree days. Tap a report notification and it opens to that report.
• Explore: the History chip is now Explore. Tap any past day to open that day's full 24 hour charts, with its high, low and rain, and step day by day from there.
• Connect Claude or ChatGPT: your server now speaks the MCP protocol. Connect an assistant from Settings, Sharing, Connected apps, approve it once, and ask about your own weather using your own subscription. No provider keys are stored on your server.
• Share to weather networks: PWSWeather, Windy, WeatherCloud, CWOP and Weather Underground from one screen. Pick which station each network gets, choose how often to send, and use Save and verify to see the network's answer on the spot. Windy uses its new station API, with the station ID and password from your station's page.
• Backups and restore: restore your server from a database backup, after a confirmation that says exactly what will be replaced. The Mac app can back up the server's database on a schedule.
• Every reading gets its own Big watch complication, one per measurement.
• Story cards for every station, and a server recommendations card when your Fly machine could use more memory or disk.
• Sign in with Fly, as a beta option, so the wizard can create a server without pasting a token.
• The station name shows on Charts and History, and air monitors keep the place you give them on the Dashboard.
• Stations that report only a lifetime rain counter now show this year's rain plus the lifetime total, and rain totals restart correctly after a gauge reset.
• A slow station no longer holds up the others: every station's current reading loads before any history.
• Changing servers saves the address and token together, and weather warnings and forecasts follow the station's location.
• Every credential you copy is copied privately and expires, the poll status dot speaks to VoiceOver, and settings are arranged by what they do.
• Many smaller fixes and refinements throughout.

### 2.0 — 2026-09-04

Your weather, told as stories worth sharing.

• Story cards: twenty-one shareable cards written from your own station's record, in your units. How Hot Is Hot, the Dry Spell, the Wildest Day, the Water Year, the Shape of a Year, the Humidity Tax, the Barometer's Call, the Forecast versus your backyard, Tonight's Sky, and more. Worth Sharing on the Dashboard picks the best of the day; the Insights tab has them all. Each has a share link with a QR code.
• The Comfortable Months: which month is the one to be outside. Every month ranked by how much of a waking day felt comfortable, this year beside the whole record.
• Rename any station from Settings, and the name follows it everywhere: alerts, storm summaries, the morning report, story cards and the public page.
• Air monitors get their picture: a 24 hour PM2.5 chart under the air card, and a CO2 hero and chart for monitors without a particle sensor.
• Govee CO2 monitors join as a cloud source (Settings, Integrations, Govee), beside AirGradient. Ecowitt gateways can now reach an HTTPS-only server through Ecowitt Cloud.
• Alerts you can arrange: sort by measurement and threshold so a ladder reads as a ladder, group by device or by measurement, filter to active or paused, and a Duplicate chip on any rule that repeats another.
• The morning report at the minute you choose, not on the hour.
• Watch stat rows now open the matching chart.
• The header shows the newest reading's time, never the poll clock, and a refresh that stalled in the background restarts instead of serving stale numbers.
• A calmer color language: one color per quantity on every screen, chart, tile, and widget, and the heat grids now show the worst hours in red instead of an orange blur.
• Charts keep the swipe-back gesture off the plot so scrubbing never leaves the tab.
• Share cards keep every word readable on a phone screen at share size, with a floor on text size across the family.
• Many smaller fixes and refinements throughout.

### 1.9 — 2026-08-30

Wake up to your weather, and show it off.

• Morning report: at your chosen hour, a report card lands on your Lock Screen with yesterday's high, low, rain, and peak gust plus today's outlook. A matching push and a beautifully formatted email round it out. (Needs the free 1.9 server update, one tap in Settings.)
• Share cards: turn your data into graphics worth posting. Storm Report, Record Book, Growing Season, Wind Event, Rain Race, Month Wrap, and Year Wrap, each rendered in the app's design and ready for Messages or social.
• Week records: records now include the past seven days, so "hottest day this week" is one glance, and any record is shareable with its period.
• Climate, the long view: year-span charts, heating and cooling degree days, water-year rain totals, and the classic NOAA-style climate report generated from your own station.
• Ecowitt gateways connect directly: point the gateway's custom upload at your server and readings flow with no vendor cloud and no extra hardware. Already running WeeWX? A small bridge extension forwards every archive record.
• Write-access sharing: hand a trusted person a link that can rename stations, adjust alerts, and register their own phone for push, while everything administrative stays yours. Every change is logged with who made it.
• Guided Setup on iPhone: no server yet? The app can create one for you, right from the phone. Paste a Fly.io token and it handles the rest, no command line.
• A new Major alert level sits between Standard and Urgent: it ignores quiet hours but arrives as a normal notification. Urgent alerts are now Time Sensitive and break through Focus modes.
• History that ages gracefully: keep years of data on a small server by thinning old raw readings while daily records stay exact. You control it from Settings, with a storage breakdown showing exactly where the bytes go.
• Storm history: past storms are now browsable with their totals, peak rates, and gusts, and storm notifications fit cleanly on one Lock Screen line.
• Glance mode: an optional simplified dashboard that answers "are we okay" above the fold. Plus Settings search, a refined card design throughout, smooth rolling numbers, and proper iPad layouts.
• VoiceOver Audio Graphs: charts now play as rising and falling tones, with spoken summaries.
• New Lock Screen widget faces for conditions, sunrise and sunset, and moon phase.
• Optional haptic feedback on chart scrubbing and tab switches (off by default, one switch to enable).
• One-tap server updates are more resilient, and future major server versions can install with one tap when the release supports it.
• Many smaller fixes and refinements throughout.

### 1.8 — 2026-08-27

Your station now watches the sky for you, and the air you breathe made the dashboard.

• Smart alerts: sudden temperature drops, wind ramp-ups, gust fronts, and sustained pipe-freeze cold, detected from your own station's readings. Related alerts arriving together group into a single "front passage" notification, and the first frost of the season gets a once-a-year heads-up.
• Alert urgency: every threshold alert can be Minor, Standard, or Urgent. Urgent alerts break through quiet hours; minor ones wait for morning.
• Quiet hours and a daily digest: overnight, only urgent alerts push. One morning email summarizes everything that fired.
• Government severe weather alerts now push through your own server, so a Severe Thunderstorm Warning reaches you even with the app closed. One push per alert, however many stations you run.
• Lightning alerts for stations that detect strikes: first strike, closing strikes, and a 30-minute all clear.
• Station health: sensor battery low and recovered, sensors gone quiet, and stuck-sensor detection (a humidity gauge pegged for hours, an anemometer that stopped turning).
• Storm Watch on your Lock Screen: a Live Activity tracks rain total, rate, and peak gust for the storm in progress, and you can start one manually when you see it coming. Hot days get an all-day tracker with the running high.
• Share to weather networks: send your readings to PWSWeather, Windy, WeatherCloud, and CWOP (where your data feeds NOAA's forecast models). Each network shows its last successful send right on the row.
• Air quality: AirGradient monitors join the dashboard as their own compact card with AQI, PM2.5, CO2, and TVOC. Indoor and outdoor.
• Backyard Science: a new History pane computes wet bulb, frost point, spray conditions, fire-weather indices, density altitude, and what a 1920s barometer would say about tomorrow.
• Your data, your rules: one-tap CSV export of every stored reading, and webhooks that POST each alert to your own automations, signed.
• Alerts & Notifications settings reorganized into clear sections, with storm summaries front and center.
• New Lock Screen widget faces, chart deep links from every widget, a Control Center button, and instant widget refreshes on iOS 26.
• For the tinkerers: the server now ships a read-only MCP connector, so you can ask an AI assistant about your stations, records, and alerts.
• Apple Watch layout refinements and many smaller fixes.

### 1.7 — 2026-08-25

Rain is coming, and now your Lock Screen counts it down.

• Rain-start countdown: when rain is expected within the hour, a Live Activity appears on your Lock Screen and in the Dynamic Island and counts down to the first drops. (Needs the free 1.7 server update with one tap in Settings.)
• Alert history: a new Recently Triggered section shows what fired and when, and you can now edit an alert rule in place instead of deleting and recreating it.
• Wind alerts got smarter: a rule re-arms only after a sustained calm period, so a gusty afternoon is one alert, not one every few minutes.
• Storm summaries got their own screen: choose push, email, or both, and mute individual stations. Summaries now catch the gust front that arrives ahead of the rain.
• Settings, reorganized: seven clear sections instead of one long scroll. Everything is where you'd look for it.
• Sharing polish: sending a link is one tap, links show when they were last used, and you can rename or re-share any of them.
• Device tokens: each sending device (LilyGO board, poller) can have its own revocable credential and new boards pick one up automatically.
• Dashboard and charts can now be customized per station, and a new side-by-side view overlays two stations on one chart.
• Widgets: a 24-hour sparkline on the home screen, plus new lock- screen circles for Feels Like, UV, Rain, and Wind.
• Apple Watch: charts on your wrist and a redesigned station card.
• Shared (read-only) links now show sunrise/sunset and severe-weather alerts too.
• Dashboard callouts respect your units, plus many smaller fixes.
