iPhone
New: build your own questions by answering in plain English, no km/h settings. Plus your day hour by hour, in green and red.
You open a weather app. You read 22°, 40% chance of rain, 45 km/h gusts. And you still don't know whether you can hang your laundry outside.
Can I? doesn't give you the weather. It answers the question.
YES, RISKY or NO — and the time.
"Hang the laundry outside? YES, from 2pm to 6pm."
"Have a barbecue? NO, too windy all day."
"Go for a run? YES, from 7am to 9am, but high UV."
SIX EVERYDAY QUESTIONS
• Hang the laundry — actual drying, not just the absence of rain: humidity, temperature and wind all count.
• Have a barbecue — gusts are a safety criterion, not a detail.
• Wash the car — pointless if rain is coming within 36 hours. The app looks ahead.
• Go for a run — felt temperature, coolest window during a heatwave, UV warning.
• Water the garden — if tonight's rain will do it for you, save your water.
• Put the plants out — frost risk over 48 hours.
YOUR OWN QUESTIONS
Cycling, fishing, painting, picnics, photography, hiking, gardening, eating outside: start from a template, or build your own.
And you don't need to be a meteorologist. You answer four plain questions — "Does it need to be dry?", "Does wind bother you?", "Temperature?", "How long in one go?" — and the verdict recalculates in front of you with every answer. The precise thresholds in °C and km/h are still there, tucked away, for those who know exactly what they want.
HOUR BY HOUR, READABLE
A strip shows your day. Green: all your conditions are met. Red: something is blocking — and a symbol tells you what, rain, wind or cold. No more numbers to decode.
THE MORNING REMINDER
Pick your questions, get the day's verdict at 7:30am. "Hang the laundry: YES, 10am – 4pm." You decide before you even open the app.
WHAT CAN I? DOESN'T DO
No account. No ads. No subscription. No data sent anywhere: your location is used to fetch the local forecast, rounded to the kilometre, and never leaves your phone.
FREE AND PREMIUM
Three questions and one custom question are free, with no time limit. Premium unlocks all six questions, unlimited custom questions and the morning reminder. One purchase, for good.
