Easy to use and helpful

Really enjoying the MHC app. Interface is easy to use and navigate. Viewing health data and trends is very helpful and clear. Feels responsive, polished, and user friendly. Excited to be using this going forward and seeing what research comes from it.

Constant crashing.

The latest version on iOS 25.4.2 is constant crashing. Can’t get in to do any of the surveys and tasks

Daily check in fine; six-minute walk broken

Generally my dialy report is easy & makes me feel useful. But for that couple of years the six- minute walk has failed to work. I start it and gives me instructions to start and never speaks to me again or records a result.
