Bucephalas
Ride with me
USD 2.99
【The full version of the Bucephalas series】
This is the full version of the Bucephalas series with the functionality restrictions removed.
A FREE version of this app, Bucephalas Tabula rasa , is also available. You can experience the features of the full version in a real ride using Tabula rasa.
【Dialogue by parroting actions】
Bucephalas recognizes your actions and attempts to interact with you by verbally parroting them back to you.
With a navigation app, you would turn right after the app indicates “right turn”. Bucephalus, on the other hand, will say “right turn" after you turn right. In addition, Bucephalus will also parrot back actions such as "stopped," "resume movement," "retreat," and "turned in the direction of the full moon.
【Functions as a cycle computer】
In designing Bucephalas, it is assumed that the bicycle would be the primary means of transportation. Therefore, it also has basic functions as a cycle computer.
• Multiple bicycle management: Bucephalas can register multiple bicycles and record distance traveled and average speed by body.
• Management of bicycle parts by distance traveled: To manage bicycle parts based on the distance traveled, the user can set up a dedicated total distance meter for specific bicycle parts such as tires and brake shoes.
• Elevation and air pressure of the current location
• Altitude gained, maximum altitude gained, and cumulative altitude gained starting from the coordinates of the app's startup
• Voice-guided navigation to the destination
• 3D sound (stereophonic sound) provides direction to the destination.
【Suggestion of destinations on two spatial scales】
(1) Global Journey = Unknotting Mode
The intersection of a grid of latitude and longitude lines drawn every 1/60th of a degree is called a knot. There are 233,258,402 knots on the entire globe. The objective of Unknotting mode is to reach a circle with a radius of 50 meters centered on the knot.
(2) City-Scale Travel = Dispelling Mode
Scaling down the grid of Unknotting to 1/60, the objective is to explore a city from corner to corner. For those who wish to explore the city in even more detail, a movement logging function called Rectangular footprint is provided.
【Destination suggestion method that does not assume a spatial scale】
Mirages are a series of randomly generated coordinates. A Mirage initially appears at a distance of about 1 km from your location, but disappear when you attempt to approach within 25 meters, and then move to another location about 1 km away. The Mirage's coordinates are randomly generated, so there is no way to predict where it will lead you.
You can switch between two mirages (Fata Morgana and Ignis fatuus) (e.g., use one as main and the other as sub).
【As a photography assistant】
Bucephalas is equipped with a Magic Hour estimator to assist with photography while traveling.
Magic Hour is the time of day when the sun is at an altitude close to the horizon and is known to produce impressive lighting conditions.
• The start time of the magic hour (blue hour and golden hour) at the current location
• Moon and sun direction from the current location
• Start time of nautical and astronomical twilight
• Calculation of the direction of the sun and moon at a specific coordinate, date, and time
【Warning】
Many of the destinations suggested by the application include those that are difficult or dangerous to approach. Please do not approach those knots by force.
This app uses GPS even in the background; continuous use of GPS will rapidly drain the iPhone battery.
【Integration with the Health App】
This app will attempt to obtain your body mass data from Health app. The data obtained are used to convert the amount of your physical activity represented in METs•Hour into calories burned. Also, physical activity recorded in this app can be exported to Health app.
