Comments on iOS
One of Dropmark’s best features for collaborating is the ability to comment on items within Dropmark, making getting feedback from your teammates a breeze. Commenting on items is a feature only available to Pro and Team subscriptions - but if you’re collaborating in a collection that a Pro user owns then, all members can use Pro features like comments and tagging, even if they’re a Lite user.
Adding a comment
To add a comment, view the item you want to comment on and click on the speech bubble in the bottom left corner. Write your comment in the text box here. Also, you can tag anyone in your team so they get a notified immediately and can reply to your thoughts.
