The FreeAgent CRM mobile apps offer you, with some limitations, the same features as the web app. Of course, this means the option to attach files to your record, in the form of images. You will have the option to take a picture straight to your record's activity timeline or select among your existing pictures.
First, select the record for which you want to add an attachment. Then swipe to the right until you get to the Activity timeline section. Here you will notice the two icons (1) right where you type in your notes. The first image allows you to take a picture, the second brings up your camera roll so that you can choose among your images.
Once you take a picture or select an existing one, it will take a few seconds to load to the Activity timeline. While it is loading it will appear grayed out at the bottom of the activity timeline. Once it finishes loading, it will be automatically added to the Activity timeline.
