Alarm when arriving at a place

The application is written from its own story:

I was on a bus that day going to a destination. However, because I was so tired, I fell asleep. When I woke up I found myself at the end of the bus stop. And I had to take another bus to get back to the destination. At that time, I thought, why don't I write an application that can wake me up when I get close to my destination, then I won't have to work so hard.

In terms of functionality, the application will alarm when you get close to a location with the distance that you have pre-set. From that need, I created this application.

Hope the application will bring convenience to you!
