1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. Chain calculator is utterly inaccurate and unusable.Chain size calc is wrong.

7. 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.

8. Especially great that there's no ads or special permissions required.

9. It would be an awesome fitting tool if it worked.

10. Thank you, developer, you legend!I use it regularly.

11. Useless.I'm quite impressed with this app.
