Distance calculator

Hi, I'm looking for an app which displays distance as a function of time and speed. I want to enter an average speed, and when I press a "go"button, it displays the distance traveled, updated about once per second. As a refinement, I'd like to be able to enter a schedule of speeds, for example 26.5 mph for 7.3 miles, then 36.2 for 3.2 miles, then 29.6 for 6.6 miles, etc..
Anyone know of anything, or is it a question of getting it developed bespoke?

"SpeedHUD" (free; in the market), intended for car driving, but will also work for bicycling or running, provides the basics of what you describe. Maybe you can work with its developer to expand it.
It works with GPS, of course. No other available positioning system has a high enough resolution/accuracy for useful/reliable time/distance calculations. However that need not be a problem as the CPU will update everything on the display in a split second when you emerge from a tunnel. You'll know exactly where you are and how you're doing relative to your flight plan.
 
Just out of curiosity, you don't want to use GPS, but you want to record/calculate distance as a Fn of time and speed?....you need GPS for this task for tracking speed :) (or at least a rough approximation).
 
No, I don't want to use GPS. Not only do we have potential issues with reception, but the vehicle has an accurate electro-mechanical trip meter which will be calibrated by using a measured distance set out by the rally organisers. If that distance is inaccurate with reference to GPS or any other measurement, it doesn't matter; what is important is that we use the same as the organisers. If their "kilometre" is actually 1.01 km, then ours must be the same.
The app Rallymeter looks like it does what I want, but it is rather expensive at 100€.
 
Hi, I wrote Rally. It will do what you want but is a bit cluttered if you use it and ignore the GPS generated information. Since it would be quite easy to alter the application to have a non-GPS driven mode I'm happy to do this. I can also integrate it with the data that is provided by the RallyData app so that a series of different speed distances can be provided and run back to back.
