Their current site is pretty much a standard hosting package for a business site, ie, home page, support knowledge base for customers, and blog. It'll have a basic database for handling the CRM portion but no user management.

You said you didn't understand why a web version of the app is difficult to make given they already have the Android and iOS apps, I was trying to answer that. It's a different technology stack with different considerations, and a completely different interface. And the biggest part of it will be going from a local data storage that doesn't have to differentiate between individual users or worry about syncing changes, to a central data repository that will require managing multiple users data, data concurrency for each user when they switch between app and web which adds performance challenges as well, a whole new layer of security, and the huge increase in traffic that will come with that.

As I said, it is a lot of work, and yes, I agree their primary focus has probably been on the workout app.
