I recommend myfitnesspal.com for nutrient tracking. It allows the client to just scan barcodes to input food…super easy.
I have recently been looking at fitview (iphone app) for tracking workouts and scheduling..haven’t played with it too much yet but it looks promising.
I also just signed up for square on my iphone to read credit cards…its free for the app and free for the card reader and they only charge you 2.9% per use.
There is nothing wrong with using technology to help with your business. It is ridiculous not to.
The answers to these past questions might help.
The Training Notebook app is pretty good. you can take photos of clients to track progress, set-up new clients, and create custom programs for clients. It was built by a personal trainer for other trainers.
There’s also an online version for tracking lots of clients from a desktop/laptop.
