About
Ever forgotten to let your family know you’ll be home late?
On busy days or when plans suddenly change, sending a message can easily slip your mind—and leave the people waiting for you worried.
Kaeru automatically keeps your family or partner updated about your journey home through LINE.
When you leave your designated location, Kaeru sends an “I’m on my way home” message.
If you’re still there after your usual departure time, it automatically lets them know you’ll be late.
No need to remember to send the same message every day.
Kaeru helps you stay connected and gives your loved ones peace of mind.
▼ Fits Your Weekly Schedule
Leave at 6:00 PM on Monday, 8:00 PM on Friday, and turn notifications off on weekends.
You can set a different usual departure time and enable or disable notifications for each day of the week.
It’s ideal for anyone whose work hours or daily schedule changes throughout the week.

・People who sometimes forget to send a message when running late

▼ No Extra App Needed for Recipients

▼ Designed with Privacy in Mind
Your designated location is stored on Kaeru’s server. When you enter or leave it, your location information (latitude, longitude, and accuracy) is sent to Kaeru’s server to reduce false detections. Location information is not sent to the people receiving your LINE notifications.
▼ Battery-Friendly
Kaeru uses location services mainly around your scheduled departure time, helping reduce unnecessary battery use.
On busy days, don’t let an important “I’ll be late” message slip your mind.
Let Kaeru make everyday home updates simple and automatic.
