Who should pick which

FitDesk may suit you if you want booking, invoices and payments in the same place as client and progress tools, without a £25 subscription.

TrainerCheck may suit you if your main pain is chasing weekly check ins, you already have a way to deliver workouts and take payment, and a plan at £25 a month, billed monthly (also listed at £240 a year) in pounds is simple for you.

Try both. TrainerCheck has a 14 day trial. FitDesk needs no card.
