There are limits to how much you can understand users' interaction with your mobile app or site if you just stick to pixels, and never leave your computer screen. You need to get designs on the device, and check if text, buttons and icons are visible, and safely clickable.
The only way to do this on every platform, is measuring with some sort of real life, physical object. Instead of muddling through with other tools, I made a tool specifically for doing this on mobile devices:
Which are the great examples of Animated Graphical User Interface (transitions, animations etc.) on mobile? Or do you know mobile apps with innovative/interesting interaction?
Do you know great, interesting, new, beautiful, user-centered, fun, or innovative animations wich can be used in mobile-GUI?
Most of the sites I've have worked on in the last several years have generated the bulk of their revenue through subscriptions or product sales. My current project is to design a mobile website for a news/magazine organization that generates a lot of their revenue through ad sales. In particular, they are looking at having a single advertiser "sponsor" their mobile website for an entire month.
I'm working on an Android app. We have some flat mocks but I want to get them onto some Android devices to see how they feel and test out flows, labels and copy with people.
In the past on iphone I've used Prototypes by Duncan Wilcox. It worked pretty well for us. I could upload pngs then add hotspots and basic tranisitions. Once I was happy I uploaded the prototype to Prototypes server, got a key and entered that into the app on my iphone. Hey presto a tappable prototype on my iphone.
Thanks to all for coming out to the AIGA Digital Dialogues talk with @gradybritton and @knuckleheadspdx on the build of the Choicelunch iPhone app. The discussion was particularly great, especially re: prototyping for the focus group and adopting a lean ux workflow, so I thought I'd post some of the highlights.
It seems the best approach for providing the capability to attach or upload multiple files at once is to make it automatic (that is, the files upload automatically, as soon as you select them--as Google does when attaching files in GMail), but the solutions I've seen are built in Flash. Of course, if you want for people to use their mobile tablet or phone to select multiple files at once, Flash won't work on iPads and iPhones.
