Need something achievable for an extremely tech illiterate person on iOS. I got told about this after they are already gone and have no access to the device, but am asked to solve the problem.
EDIT: (SOLVED) Signal was super easy, works awesome, and was easy even for my mom to figure out on her own. Thanks
I only needed chrome for installing GrapheneOS. They integrate the install into the chrome browser. Sorry if the was not clear. This is how I first encountered Matix. Graphene embeds a matrix client in to installation web page, so if a new user needs help with installation, all they need to do is use matrix. This is how and why I created a matrix account.
