It's awesome when some of our posts get attention enough to get people interested in showing their work. That's exactly the case of the Dear Future Astronaut NY, a Swedish creative group.
They told us about their app for the iPhone called "Reinstall My Apps", which is beautifully designed. Unfortunately, it got rejected by Apple, so you only get to see the design screen shots. About it, they say:
Remember how earlier you did not have the Purchases tab in iTunes App Store on iPhone? So if you removed some app from your device and wanted to reinstall it, the only option was to try to buy it again and if you already purchased it your card won’t be charged. But if you missed the name or the version (ex. Was it Angry Birds Rio or Angry Birds Seasons I had bought?) you would end up buying the second app.
So Dear Future Astronaut AB developed Reinstall My Apps which provided users with a searchable history of all purchased apps which can be reinstalled for free directly from the list. The app was completed and fully functional and submitted to Apple for a review. But Apple rejected it and, fortunately for the users but unfortunately for the app in question, introduced that missing feature directly into the App Store. So, now it can be only used as a good example of app development project.
To check more of their work, please check out their portfolio at Behance. They'll appreciate it. I hope you enjoy these. Cheers! ;)
