Spoke Tensioner

The Mad Stomper

About this app

Enter the type of spoke into the app, then pluck the spoke and it will display the tension for that spoke.
Much faster and more precise than using a hand held spoke meter.
Incorporates nearly all spoke shapes, sizes and materials.
Technique is used by major wheel builders, based on fundamental physics rules.

Ratings and reviews

I am very satisfied with this app. I was leaning toward purchasing a mechanical meter, but I decided that inexpensive mechanical meters are probably only good for measuring relative tension because the calibration can be way off.. After hearing good things about a similar app for the iPhone, I decided to give this one a try. There was a bit of trial and error to get the plucking technique just right (i.e., lightly!), but I felt confident that I was getting very repeatable readings.

The app works exactly as advertised, used it to true a WTB ST i27 29" wheel with the correct tension. Definitely worth the money when compared to a physical tensometer. The GUI could use an update (not having to scroll to find the diameter and length of spokes), but once the parameters are set up, it is easy to use. Also loved the explanation of the physics behind the app. The app also contains a short tutorial for wheel building, describing how to solve common problems.

Precisely what I was looking for. Already knew I had to tension by frequency, but this makes it soo much easier than asking my wife if the spoke is lower or higher in pitch. No fuzz, just exactly what you need, no more no less. Pricing is low enough for a impulse buy. Keep up the good work!
