iStratus® is the best place on your Apple device to gather data. The Imports tab is where most items arrive. From there, you may want to move an item to a more appropriate folder or you may want to mark it as a ToDo so it displays on your Calendar tab until you deal with it. Below are some ways to conveniently import items into the app.
Other Apps - Other apps on your Apple device, such as Mail, allow you to save documents into apps such as iStratus®. See the 4-page PDF below for a quick tutorial.
Web-Link - From Safari, take notes on a webpage and save to iStratus®. See the screenshot below for instructions on how to set this up in Safari.
Also, don't forget about your "iStratus Daily Drop" folder, which is created for you at the root/top-level of Dropbox. This folder is convenient for when you want to quickly drop off some items from your desktop or laptop. You may even want to share this folder with others, such as your secretary.
