I had to uninstall and reinstall FourSquare today so I could use it with OS 4.0. Doing so I found the app has changed a lot since I first installed it before SXSW 2008. Besides being prettier (well done, Mr. Rainert) there are prompts to scrape your Twitter, Facebook, and Contacts lists for friends using the service and a nice flow for new users to join.
As an early adopter of many iPhone apps this makes me wonder what other innovation I’m missing. The initial load and experience for new app users is very important, it’s the first interaction your app has with your customers, but it’s often overlooked—especially in alpha app releases—since you do it once and that’s it.
The next time I find myself creating a flow for an app, maybe I should uninstall a few of my favorites, reinstall them and sign-up as if I was a new user.
