Bicycle Calculator (BikeCalc)

Chain calculator is utterly inaccurate and unusable.

Chain size calc is wrong. Useless.

I'm quite impressed with this app. Not tried any of the spoke length calculations but checked it against other apps and it seems more consistent and clearer about the flange possitions. Not sure if it's just my phone or my eyes but it appears to miss out a decimal point in the inches part of the frame size result. A small fix I'm sure for the developer who's done a great job with this app.

It has tools for building a wheel, cutting chain, calibrating a cycle computer, picking the right cassette, chain rings and rear derailleur. I tested them all and the only one that isn't accurate is the frame calculator; it's not using the rider's (inseam, torso, arm lengths) measurements and tire size plus frame geometry to calculate: frame size, stem length handlebar width and seat post position. It would be an awesome fitting tool if it worked. It would probably be way too complex to be accurate though.

not every one is an expert biker you now or a perfect english speeker plus it seems they are tehnical data. regards,

apps is good but why there is no exit option to close the app，every time i need to force close the app.

The best spoke calculator I've tried. Use this just about every day in the workshop. Especially great that there's no ads or special permissions required. Thank you, developer, you legend!

I use it regularly. Spoke calculator is more accurate than any other I've used.

I use it very often at work and home.

I can't read the calculation results as they are black on really dark grey on my dell streak

Great app, good use.

Trying put info for bike size and it gives me no help.

I cannot move it from my phone memory to my SD card.

I am a USAC licenced mechanic and thought this would a handy app. I am unable to make heads nor tails of the calculations in this app.
