Plancast, the plan-sharing startup with big-name angel investors and "future as platform" aspirations, has just had its iPhone app accepted into the iTunes store. The app was built by contracted star developer Leah Culver. It's simple, functional, attractive and useful. It's going to be very good for SXSW and probably beyond, if the service continues to stick with users as it has so far.
Here's the iTunes link and below you can see some screenshots.
