About this app

You think, "I still have plenty of time," but before you know it, the departure time has passed.

Yotemi is a reminder designed to eliminate that "before you know it" moment.

It calculates the "departure deadline" you need to make to arrive on time from your Google Calendar appointments.

Then, the remaining time is simply displayed as a countdown. There's no need to calculate the time or set an alarm yourself.

■ What it can do

・Automatically calculates the departure time based on the start time and location of your appointments.

・Displays the remaining time as a countdown in notifications and a home screen widget.

・The remaining time continues to update even when the app is not open.

・Notifications gradually increase in intensity as time approaches.

・Detects whether you are traveling by train, walking, cycling, or driving, and estimates the time required for each.

・The more you use it, the more accurate the estimate becomes, based on your actual travel time.

■ How to use

1. Link with Google Calendar.
2. Add a "location" to your appointments.
3. Then, just wait. As your departure deadline approaches, a countdown will notify you.

You can register your schedule via the app or by voice.

■ About the Design

There is no "just 5 minutes left" snooze function. Time waits for no one.

Instead, notifications automatically intensify as time passes.

The screen prominently displays "X minutes left," not "X:X:X."

This is designed to match the feeling that just looking at the time doesn't give a clear sense of how much time is left.

Green is a signal that it's time to start preparing, not a warning.

It's designed to help you act calmly, not to rush you.

■ For those who:

・Struggle with time estimation and always end up cutting it close

・Always decide on a start time for getting ready somewhat haphazardly

・Add appointments to their calendar but forget to leave

■ Pricing

You can use the service for free for up to 5 travel-related appointments per month.

For more than that, paid plans are available.

■ About Permissions

* Location Information: Used to determine departure, travel time, and arrival at destination.

To ensure the countdown continues even when the app is not open, selecting "Always Allow" will maximize functionality.

Countdown and notifications will still be available even if permission is not granted.

* Calendar: Reads the start time and location of appointments and writes back appointments created and edited within the app.

The acquired location information will not be used for advertising or sold to third parties.
