Mr. Jim Finnie.

Great support and advice, leadership in the classes is straight forward and easy to comprehend.
I look forward to going each time 🤗

Awful

Not the most user friendly app . Nothing but problems

Not user friendly

Too many falls in and out of menus. No way,I can see, to search by class rather than venue. Also you cannot as a parent book for yourself and your child. This may become irritating when attempting to book popular classes. For example I book a slot for myself, go out of my app/account and into my daughters and all the remaining spots are gone, meaning I’ll have to cancel my spot.
