Good basic calc.
This is a handy app for calcs, with good but basic features. The calcs line up perfectly with leonard.io/edd, which is my preferred web spoke calc. In future versions, it would be great to be able to sort the saved wheels by name/date/etc and to save wheel sets / pairs instead of only individual wheels. And to the reviewer complaining about straight pull spokes - they are measured exactly the same way. Any spoke calculator can do straight pull spokes if you can get an accurate flange diameter measurement. Please take your wheels to an experienced builder instead of blaming this app ... ✌️
