洗濯日和。「今日、洗濯物を外に干しても大丈夫？」

"Is it okay to hang laundry outside today?"
Sentakuiyori answers these small daily concerns.
It makes a comprehensive judgment by combining temperature, humidity, wind speed, and precipitation probability—information that weather forecasts alone cannot provide—to determine whether you can hang laundry. You can check at a glance whether it's okay to start laundry right now.

■ Main Features

Outdoor Drying Judgment
Based on weather data for your current location, it displays whether outdoor drying is possible in three levels:

• You can hang it! (Outdoor drying OK)
• Be careful (conditions apply, such as strong wind or high humidity)
• Better not (rain, snow, or 30% or higher precipitation probability)

The judgment takes into account the entire time period from "starting to hang" to "taking in." If there's a forecast of deteriorating weather partway through, we'll notify you properly.

Today's Recommended Laundry and Drying Times
Set the washing machine runtime and laundry type (lightweight, regular, heavy, or bedding), and it automatically calculates the optimal start time for washing, time to start hanging, and time to take in. Set the 3-step alarm, and you'll never forget to take in your laundry.

Hourly Drying Efficiency Graph
Displays a bar graph showing how easily clothes dry at each hour today. You can see at a glance "what time is easiest for drying." The graph auto-scrolls to the current time, so you can quickly access the information you need right now.

Take-In Reminder Timer
Choose a timer duration from 30 minutes to 4 hours and start it. You'll get a notification when the time is up. You'll never forget laundry hanging outside.

Drying Times Tailored to Laundry Type

• Lightweight (T-shirts, underwear, etc.): approximately 2 hours
• Regular (shirts, pants, etc.): approximately 3 hours
• Heavy (sweaters, jackets, etc.): approximately 4 hours
• Bedding (futons, blankets, etc.): approximately 5 hours

Simply select the laundry type, and the drying time used in the judgment automatically switches.

■ Recommended For

■ About Weather Data
