Have you ever taken an umbrella with you when you heard it was going to rain in the morning, only to leave it behind at a cafe, restaurant, school, or office on your way home?

Umderella is not just an app that tells you to "take your umbrella."

Umderella is an umbrella loss prevention app that helps you remember everything from the moment you take your umbrella on a rainy day until you bring it back home.

☔ Recommended for:

• Those who frequently lose their umbrellas

• Office workers who leave their umbrellas behind during their commute

• Students who leave their umbrellas at school or in classrooms

• Those who buy a new umbrella every time it rains

• Those who frequently forget important items

🌧 Automatic Rain Detection

Umderella checks weather information and automatically notifies you when it is raining.

Because it only operates on days when you need an umbrella, it does not bother you with unnecessary notifications. 📱 Lock Screen Reminder

On rainy days, a reminder screen appears every time you turn on your phone to help you remember your umbrella.

It is designed not as a one-time notification, but to keep you remembering until you actually take your umbrella.

🎒 Umbrella Retrieval Log

Try pressing the "I took my umbrella" button before you leave.

Umderella remembers that you took your umbrella with you and helps you retrieve it when you return home.

✅ Retrieval Check

Before you return home, press the "Retrieved" button on the lock screen to complete today's umbrella mission.

A small habit helps reduce umbrella loss.

Instead of complex features, the warm and comfortable design makes it easy for anyone to use.

Reduce the minor inconveniences of rainy days and lessen the stress of losing your umbrella. 💡 Um-derella solves these problems
