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.
