Perfect autosave

One of the challenges in mobile design is informing the user something has happened -- a form has been submitted or field update saved. The boring and accepted way to do this is a popup window that says "You just did something!" And if your developers are over thirty, they probably will insist on putting a confirmation button to dismiss the window. Under 30, they probably have the window fade after a second or two, or when you tap out of it. Without this, the change might be subtle enough that you are unsure what if anything just happened, and depending on connectivity, the ubiquitous loading animation may flash too quickly to do little more than add to the confusion. And don't forget by adding text to a confirmation window you are creating another language/data element to worry about when you decide its time to go multi-lingual.

So I would like to give this to the world, the perfect autosave image.

Take it, use it, enjoy it.  Me? I use it when a user updates via select/dropdown, or clicks into a field, makes a change, then clicks out -- the image fades in then out a second later. And as a bonus, I add this sound effect which reinforces that something has indeed occurred.

Enjoy!
