I train groups of 8 senior clients all with individual workouts. Is there software for iPad, iphone to manage these sessions?

First off, Grace’s app recommendation is an excellent place to start in my opinion. There’s even a free version of it which is great if you want to try it before you pay the full price of $14.99. Also, there seems to have been numerous updates to improve the app since it was first released by the developer - usually a good sign if you ask me.

Am I correct in understanding you’d like to use the app during and after your group sessions to track and manage client programs?

If so, another iPad app that might be of interest to you is called “All My Patients” ($9.99). At first glance it’s clearly meant to be used in a medical/hospital setting. However, with a bit of creative re-purposing I’m sure you could utilize it in a way that suited your needs. For instance, in a single file you could have all the “seat settings, weights, and reps” on the same page but separated into different boxes (one for each group member) for one specific group of clients. Or, you could create individual files for each of your clients and include the desired data/notes. It might take a bit of time getting used to the interface, but if it gets the job done that’s a win in my books!

Here's some more info on "All My Patients" if you're interested: https://itunes.apple.com/us/app/all-my-patients/id471474680?mt=8

Let me know if I can be of any more help. Happy data tracking/note taking regardless!
