Trainer's story about FitDesk
“Having been in the fitness industry for the last 12 years this is hands down the best software I've used. From the booking system to payments, workout & meal plan section is incredible. Everything is conveniently in one place without the need for multiple apps.”

Trainer's story about FitDesk
“This App is fantastic, it is simple to use and not confusing whatever. It is clear and you only get what you need, no fluff. It keeps track of your progress so you can really see your growing progress overtime. It is constantly undergoing improvement for a better experience and it's wonderful to see.”
AlfTrustpilot
Trainer's story about FitDesk
“I think its fair to say that I have been working with the ongoing developments on FitDesk for a fair time now and it is going from strength to strength. It is tailored to PT's and clients and is not at all interested in taking money 'for old rope' such as basic menu preparation for nutrition, sending emails, invoicing or indeed branding it to your business. There are no hidden adds on and its free!
I WOULD pay for the app and web applications without any doubt. Everything is where you need it all in one package-simple, dedicated and developed for the right reasons. I have left Trainerize!!”
