I am creating a Running App. I am trying to compute the distance run after Button is pressed (start running/walking) adding the distance of each segment. The next point of the segment is update every 5 seconds of walk/run getting the new location. Why is it that the “Total distance” run/walked does …

Why are you converting the angles, already expressed in degree, as if they were radians? All the trigonometric functions work with degrees. This, by itself, makes all your calculation off by nearly two order of magnitude.

I am not good in mathematics…however I have read that even though you can use both degrees and radians in trig functions, yet, usually they have to be converted to radians in the Haversine formula ( https://www.movable-type.co.uk/scripts/latlong.html ). I am not trying to convert radians to degree bu…

The fact that when you pull down the “sin” function from the math tool box, it comes with a preset “45” stand-in argument si already a strong hint that all the trigonometry functions in thunkable are working in degree. You do NOT need to convert anything. The haversine great circle function that y…

I also make a running app now, but I it did not work properly… Could you give me some advise for me? (here is my project→https://x.thunkable.com/projects/600186977471a1001127ab08/ffe2fbf7-919d-44de-9b26-8cb9de074153/designer)

[image] summer7060.seedjpr: Thunkable i will need to research but can u use accelerometer and try

Thank you, I gave it a try but I think when you work out, the position of the smartphone can be changed. So I think we can not make the use of accelerometer.

then maybe we also need to include gyroscope

I think x , y, z axis is fixed with the iphone, so we cannot use the formula. (We cannot know how users hold it) gyroscope also use axis I think :sob:
