I found this site https://www.useronboard.com/ to be quite a useful resource for looking at the on boarding process.

Along similiar lines, my company is running an ongoing series of teardowns that pick out user experience obstacles on well known websites. We do a pretty rigorous analysis, both for onboarding and everything else.

So far we've done a saas product (http://www.smoothconversion.com/blog/mouseflow-web-funnel-te...) and a big media site (http://www.smoothconversion.com/blog/everyday-health-web-fun...). More are in the pipeline.

while on onboarding is there any plugin/gem for ruby on rails that makes it easier to create a guided on boarding ?

I'm so very sorry.

Making a good first run involving BlueTooth pairing is... a challenge to say the least.

My team spent over 2 months trying to design a good flow. We failed. We still meet regularly to try and improve it, but we are never sure how successful we can be.
