**Personal Weather Station & Aviation Weather** Connect a PWS via Weather Underground, monitor aviation weather from any METAR airport, or track tides and coastal conditions from NOAA CO-OPS stations. **Three station types** • PWS — personal weather stations via Weather Underground • METAR — airport observations, updated every few minutes at most US airports • NOAA — tide gauges and coastal stations **Current conditions** Live readings with charts underneath, plus the record high, record low and average for today's date from your station's full archive. Up to 12 metrics depending on station type: temperature, feels like, humidity, wind, dew point, pressure, precipitation, UV, solar radiation, visibility, water temperature, and water level/tide. **Rich history charts** 1-day and 7-day charts you can drag to read exact values, times and wind direction. US airport stations fill in between the hourly reports, so today's line is a curve rather than 24 steps. **Alerts** Get notified when your station crosses a value you choose — a freeze, a gust, an inch of rain — or when it stops reporting altogether. Pressure drops, temperature swings and wind shifts are built in as ready-made rules. **Customisable units & display** 12- or 24-hour time, metric or imperial, and precision options for every number. **Color themes** Nine palettes for your charts and calendars. Preview any of them across every metric before you decide. **Widgets (Supporter)** Graph widgets for any metric over 1 or 7 days, a single-metric widget for one big number, a year-at-a-glance calendar, long-range history charts, a records widget, and Lock Screen complications. **Watch app (Supporter)** Temperature, feels like, humidity, wind, pressure and precipitation as watch complications, with every current metric and its graph in the app itself. **History & Records (Supporter)** Daily detail for any year your station has recorded — airports often reach back decades — plus all-time records, a record high and low for every calendar day, and yearly trends that overlay up to ten years on one chart. Free includes current conditions, 1-day and 7-day charts, one month of history, one alert per station, and three colour themes. Note: a Weather Underground API key is required for PWS stations. METAR and NOAA stations are free and need no API key. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: RainMaker_CWIP at none against Backyard Weather's 1. RainMaker_CWIP also leads on iOS requirement (15.6 vs 17.6). Backyard Weather's advantage is update cadence (every 3 weeks vs every 12 months) and device support (3 vs 1). On price and ads there is nothing between them.
