How can I edit or change the name of a habit or the photo associated with it?
Unfortunately, for now there's not a way to add a photo to a habit or to edit a habit name. Maybe we'll be able to add this in the future.
There are two ways to approach goals using Coach.me. One is to add daily habits that you want to develop. The other is to use a step-by-step plan with specific tasks and coaching to get you towards your goal When you create a plan, you do get access to add an image and editing capability.
Creating a plan is overkill if you just want to add a photo, but if you're hoping to add more details about your habit, a plan is a way to do that. Follow this link for more on creating plans.
