Announcing: MIT App Inventor Open Beta Preview

“For the past two months, we have been conducting a closed test
of the system for an increasing number of testers, and we?ve
currently scaled to 5000 testers. Today, we?re taking the next
step, and opening the MIT App Inventor service to everyone. All you
will need is a Google ID for log-in (for example, a Gmail
account).

App Inventor will now be suitable for any use, including running
classes. But please be aware that this is the first time the system
will be under load from a large number of users, so there may be
bumps and adjustments as the load increases. For now, we suggest
that you maintain backup copies of important apps, as we see how
things go.
