I bought this a while back but didn't do much with it as the UI was confusing and had a few pesky bugs that kept stopping me in my tracks. After a bit of hiatus, I am back blogging again so I checked out the app again and I am glad to see that they have been hard at work quashing the bugs, making great strides toward a streamlined and clear UI/UX. One of my biggest gripes previously was that it was hard to see if your site will be relevant to the link requester and vice versa as you are relying on the description they have provided but you couldn't see the URL until you accept it. This has now been resolved and the process is much better and clear.

In terms of how quickly it takes to build, that depends on how quickly you and the other person perform the relevant steps. It could literally be a matter of minutes/hours or weeks.

Hopefully, they can add more linkable sites to the portfolio and continue making improvements.
