かえるね - ワンタップで帰宅連絡

This app lets you send a "I'm on my way home" message to your family with a single tap before getting in your car after work.

■ For people like this:
・Those who commute by car and whose return times vary daily
・Sales drivers, construction/equipment workers, visiting nurses/caregivers, delivery drivers, etc.
・Those who don't want to use or let others use their smartphones while driving
・Typing messages on LINE every time is a hassle

■ What you can do:
・One tap of a giant "I'm coming home" button → Share a message with your family, including your estimated arrival time, via LINE, etc.
・The estimated arrival time (ETA) gets smarter the more you use it (learning type). It learns your driving patterns and improves accuracy.
・After sending, it switches to the "Monitoring" screen, where you can see the distance to home and elapsed time in real time.
・Automatically detects arrival when approaching home (does not constantly acquire location information; safe design that only acquires information when sending and during monitoring).
・Can also send directly from the home screen widget.
・Includes a signal that changes the color of the sky depending on the time of day, and a "sunset chime" sounds in the evening.

■ We value your privacy:
・No constant location tracking. Location information is used only at the moment of transmission and during monitoring (from transmission until arrival).
* No ads, no access analytics, no account registration required.
* All return logs, location information, and learning data are stored on the device. They are not stored on external servers.
* When setting home or work by address, the entered address is sent to the Geospatial Information Authority of Japan's map service (search only; not saved).
