Hello All, 

To all the users who were looking for options to annotate your thoughts on the images and add them as attachments to Tasks and bugs from within the Zoho Projects mobile app, in the latest version of the app (both Android v3.2.18 and iOS v.3.2.14), we have brought in support for the Annotator feature. 

I have attached a GIF below for your reference: 

Do try out the feature and share your feedback in the comments section!
