The provider app doesn't have enough functionality to really be useful (this seems to be an issue with all booking systems..) The main disappointment: The features don't work together, even if following the slightly convoluted instructions of roundabout ways from customer service. 2 way sync is pointless - if you're like me and that feature was a main driver to sign up, don't. Bookings for group sessions synced to the calendar create an 'external event' and therefore block further bookings for that time block. The system doesn't recognise it's own bookings. If you're a solo entrepreneur with a life who can't spend constant time on a laptop to block out times in your calendar AND the booking system, this unfortunately makes the whole thing obsolete.

No support or system interface in the Czech language Settings are divided into several interconnected tabs, so it’s sometimes necessary to double-check that one change hasn’t affected another area

The only reason I would take off a star or move on down the road is that it isn't a complete white label solution. You still have to use their favicon, but it should be an easy feature for them to add in future. There is a learning curve to use site with all of its features.

The system could not handle volume at scale. It was not easy to use, and froze/glitched regularly.

One area for improvement would be to offer customizable revenue-sharing options. I'd love to see a way to implement revenue splits between each service provider and my company, which would open even more opportunities for collaboration and growth.
