This milestone contains various work items wanted in the original first two prototype releases, but deemed out of scope. Not of all of these work items are expected to be completed, but instead as many as possible should be completed.

Deliverable: the Oppia app should have the complete fundamental learning experience currently provided by the web platform, plus offline access. This includes full support for Oppia accounts, persisting progress in the backend to share across multiple devices, recording statistics from devices, recording progress locally for lessons (which is a stretch goal for the prototype), full interaction support, and additional features needed in the learning experience such as pre-tests and post-tests. This milestone also includes providing an onboarding flow for users, app settings, and admin settings beyond the minimum needed in the prototype. This also includes introducing landscape support, and possibly large layout support for tablets and Chromebooks.

Note that this includes all work from prior prototype milestones.
