Will tonight’s sunset actually be worth it? Helio tells you before you go. Helio uses real weather and an ML model to rate how good every sunrise and sunset will be at your exact location — on a clear, simple scale. No more guessing whether to grab your camera or just step outside. What you get: • Sunrise & sunset quality scores — every day, at a glance, for your exact location • Built-in weather — see the conditions that shape the sky before you head out • Multi-day forecasts — plan shoots, hikes, and trips around the best skies ahead • Community Reports — real sky conditions from people near you, live on a map. Rate your own sunset to help everyone call the next one • Top Predicted Spots — discover the places worldwide our model expects to have a genuinely great sky tonight (only the standouts make the list) • Clean, fast design — the answer you need, none of the clutter Whether you’re chasing golden hour for the perfect shot or just want to know if tonight’s sky is worth looking up for, Helio turns “maybe” into a plan. Free to download. Upgrade to Helio Premium for extended, longer-range forecasts.

Rainไหม? (Rain Mai) One question, one screen: is it going to rain in the next 30 minutes? Rainไหม? tells you nothing else. No weekly forecast, no temperature charts, no settings to tune. It is built for the moment you are deciding whether to take the motorbike out, or whether to put the awning up. ■ Current location or city search Use your current location or search for a city. Location permission is optional. Save up to five cities for quick access. No account is required. ■ Four answers Sunny, cloudy, rain, or heavy rain. When rain is coming, it also tells you roughly when it will start. You also get the expected precipitation for the next 30 minutes. ■ A scene, not a number Instead of percentages, you get an illustration of what people in Thailand are doing in that weather right now. ■ About your location The app reads your location only after you choose Use Current Location. Coordinates rounded to about 100 m are sent to the Open-Meteo forecast service, and the app does not store them. It never reads your location in the background. City search and saved cities work without location access. No ads, no analytics. Weather data by Open-Meteo.com (CC BY 4.0)
