About this app

Demumu — Personal Check-In App

Demumu is a simple check-in app for people who want a trusted contact to be notified if they do not check in on time.

⏱ Set a Check-In Timer
Choose a check-in interval of 12, 24, 48, or 72 hours and start the timer.

👆 Tap “I’m OK”
When you are okay, tap the button to reset the timer.

📧 Missed Check-In Notification
If the timer expires without a check-in, Demumu sends an email notification to your trusted contacts.

👥 Add Trusted Contacts
You can add up to 5 trusted contact email addresses.

🔔 Local Reminders
The app can send reminder notifications before the timer expires.

🌙 Simple Design
Demumu supports a clean interface and dark mode.

Who Demumu Can Help

Demumu can be useful for adults who live alone, older adults who want a simple daily check-in routine, students, remote workers, people traveling, or anyone who wants trusted people to know if they miss a check-in.

Example Situations

You can use Demumu when living alone, during solo travel, after moving to a new city, while working from home, or when a family member wants a simple way to stay aware without constant calls or messages.

Important Notice

Demumu does not provide emergency response, real-time monitoring, location tracking, medical support, or professional safety monitoring.

It is only a personal check-in and notification tool.
