App Builder — APIs & Real Apps

Apps that talk to the real internet. Students pull live data — weather, zmanim and more — into their own apps, train in professional debugging (including catching the AI when it's confidently wrong), and plan and ship a polished multi-feature capstone the way a working developer would.
