This means something like a page where the calculation method and or formula is displayed. Oh yes, on the result screen, please fix the spelling mistake. Length is spelt l-e-n-g-t-h not l-e-n-g-h-t. ### 3/5 — Spoke holes? *2018-02-24* Love the app, however; I am wondering about the measurements of the spoke hole flange centers. I have always measured from the inside of one hole to the outside of the opposing hole to get the center measurement. Assuming this is not a mistake, maybe we can get an explanation of how this measurement works. ### 5/5 — The best Spoke app so far! *2018-01-26* This spoke calculator thus far. If you are a novice it is perfect. It is straight forward and has nothing complicated about it. Keep up the work. ### 5/5 — The best *2017-01-05* The only thing I can say is the best app on my phone ### 4/5 — Simple and to the point *2014-01-04, version 1.1* This is a nice easy, handy spoke calculator. It would be nice to see a few of the more unusual lacing patterns (like 2 or 3 lead,return). ### 1/5 — Way off! *2013-10-24* I input the data requested taking precise measurements of a current wheel build with known numbers, and this calculator came up 5mm's too long. That is horrible! ### 4/5 — Nice *2013-02-06* Nice job, needs a little work. But in all works. ### 5/5 — Simply the best *2012-07-15, version 1.0* Ease of use Clear instructions Simple design What else can I say? Well worth the money. So much easier using your phone than running to the computer or using net based calculator. It effectively calculates the spoke length not just a database collection. Although if yo want different patterns on DS and NDS you have to do it twice. What you can't see from the photos is that the flanges are measured from the two locknuts separately not from the centre of the hub. Great app, well done! ## Frequently asked questions about Spoke Wizard ### How does Spoke Wizard calculate spoke lengths?
