Evolution is a wonderful thing (relax, creationists — we’re only talking the electronic kind here), and iPhone app Twitcal‘s transformation today into SnapCal brings big changes along with the name switch — not the least of which is that the cool little app is now free (down from $3) through iAd support.
For those who aren’t familiar with the app, SnapCal lets users broadcast event details through Twitter, which can then be easily imported into the app’s calendar by other SnapCal users. Events can also be auto-updated by following another user’s calendar. And now, the app can also import events from Evernote and sync with Google Calendar.
SnapCal can also be freed of its iAd shackles for a buck through an in-app purchase.
