Guidable is an app (iOS and Android) that helps experts create and sell guided programs to their followers.
I set up a simple 7 Day Blogging Challenge on the app. Had a couple of minor issues. 1. Adding content was a little time consuming as I had to do it on my mobile. Would be great if you could add it via desktop to cut and paste and repurpose from other content. In my case, I took content from an email sequence for a month long challenge. 2. When you click on the button to follow a link, it takes you to the page within the window and then you can't flick back to the previous one without closing the app first. This was a little frustrating. I'm looking forward to seeing if this app converts.
Simple, could be a novel way to attract leads
Have to do the content on your phone, which is time consuming and clunky
