In need of a mockup that shows the versatility of your app? Then take a look at this scene from Placeit, featuring two young women, sharing something with each other, on two phones. The relaxed atmosphere means this scene could work for so many different types of apps or mobile responsive websites. These ladies could be sharing the newest social media app with each other, for example; or comparing dating profiles, exchanging photos, checking out the latest mobile shopping app, etc. There's really no end to the possibilities here. But what truly makes this mockup such a great marketing tool, is the fact there are two different types of phones. Here we have Sony Xperia and a Galaxy Note, both screens are perfectly positioned for you add your own screenshots. Plus, having your app's screenshots on both phones will show people that your site works with all kinds of devices.
