Everyone at my gym uses the training notebook iPad app. It’s been a real invaluable tool for my business. “about time” was my first reaction when I first started using this app and I use it everyday. It helped me organize my clients so I can better manage them. I no longer need to have 3-4 apps to train my clients and the app is really user friendly. I recommended to all my trainer friends.
