How many mph? app for iPhone and iPad

This application can measure the speed of the ride now.
It can measure with various vehicles such as bicycle, motorcycle, car, train, bus, airplane, ship. Of course, even if you are not on a ride, such as walking or jogging, you can measure the speed if you even launch the application.
Since you can also measure elapsed time, travel distance, maximum speed, average speed at the same time as speed, I would be happy if you could use it as a kill time or a simple record of traveling time that you commute to work, school, travel etc.
Furthermore, since my whereabouts are always displayed on the map, you can know the current speed while checking your current location on the map.

Example of use)
· Measurement of maximum speed and lap time at bicycle commuting and commuting.
· When you thought that "How many miles per hour, right now?" while riding a train.

· When you are concerned with the current location check and speed while getting on the bus.
· Measure distance and traveling time from home.
· Measurement of average speed during car movement.

Notes)
1. In order to improve the positional accuracy at the time of tracking, this application acquires the position by GPS at the same time as it starts up. We always fine-adjust the position of the map so that the center of the map becomes the current location. Due to this effect, if the location of the loaded tracking data is different from the current location, please note that the map may move to the current location immediately after loading and it may be difficult to check the loaded tracking data.
2. If the movement speed is too fast with respect to the maps enlargement rate, updating of the map can not catch up, and the marker at the center of the map may disappear. In that case, move the map a little with your fingers, or press the STOP button and press the START button again to restore the marker. In addition, even in the state where the marker disappears, various measurements are continuously performed, so there is no influence on the data.
