• New Electricity block: the hourly power price for today and tomorrow, with the sun on top. With a dynamic tariff you see the cheapest hour, with solar panels what your roof generates, with a fixed tariff the greenest moment. Plus a planner for charging the car, a home battery and a water heater. • New block "How right was Helder?": what Helder forecast yesterday next to what was measured, for temperature and showers. • New alert for slippery roads: a heads-up when snow, freezing rain or wet roads freezing are likely. • Thunderstorms are spotted more sharply, using the lightning potential of the German weather service. • The forecast now comes from our own server in Germany.

• The moon: full and new moon now also show on the evenings around them — the moon looks full for a few nights • Small improvements

• Helder on iPad: portrait like on the phone, landscape with the map on the left and Today on the right • Today refreshes itself every five minutes while the app is open • The map loads faster: lighter frames and better caching • Outdoors: wind gusts now count in the scores, with a storm cap for cycling • Rain strip and graph say "Rain now" when it's already raining • Small improvements and fixes

• Wind gusts now count in the scores for cycling, running, walking, outdoor sports and terrace — a 55 km/h gust is what you feel, even when the average is 25 • Cycling gets a storm cap: with gusts of 75 km/h or more, never above a 4 • Rain strip and rain graph now say "rain at 4 PM" when the rain is more than an hour away, instead of "in 2:55 h" • Map layers load faster: frames now come from the nearest server

• New home screen widget Outdoors: scores for cycling, running and terrace in small, medium and large — same curves as in the app • Rain strip widget now looks 2 hours ahead, and tells you when the next rain is coming when it's dry • Widgets follow the app's theme (light, dark or system) and refresh after an update • Terrace: rain in four steps, from drizzle to downpour, instead of one big penalty • Radar beats the model: if live radar says dry, a model drizzle no longer lowers your scores • Coming days widget hides rain chances below 10%

• Outdoors: fairer scores in heat and strong sun, a heat cap for exertion, and tap a bar to see that hour • Our own rain forecast (Helder) is now the default: rain strip and rain graph up to 8 hours ahead, no switch needed • Rain strip and graph: lead times in hours instead of hundreds of minutes; a cleaner graph • Map: faster loading, and in North America NEXRAD radar with nowcast plus 8-hour, temperature, wind and pressure layers (NOAA HRRR) • Units °F, mph and inches automatic by region; 12- or 24-hour clock follows your device • Search shows the state or province (Denver, CO) • Stability: fixed a crash when switching between Europe and America

• Units: °F, mph and inches — automatic by region, or set them yourself • Map in North America: NEXRAD radar with nowcast, plus 8-hour, temperature, wind and pressure layers (NOAA HRRR) • Outdoors: fairer scores in heat and strong sun; tap a bar to see that hour • Search shows the state or province (Denver, CO) and the country • The clock follows your device: 12 or 24 hours • Stability: fixed a crash when switching between Europe and America

Helder now runs on KNMI data: a real measurement for now, HARMONIE and ECMWF for the forecast, warnings from MeteoAlarm. New: our own rain forecast up to 8 and 24 hours on the map, with an uncertainty band, and an experimental switch in Settings. Plus small improvements to the charts.
