You do have to go to the website itself. But I did mine using my phone. I used the Google chrome app for internet, went to
medhelp.org, logged in and added my profile pic easily. Hope that helps and good luck!
I asked this apparently u have to go on the full website
Unfortunatly you cant do it through the app, you have to do it on a desk top through your account, unless another mommie has figured out how. I know just switching from mobile view to desktop view on my tablet still wouldnt let me i had to do it on a desk top computer
