# Native apps

> Level 2 integration for native learning apps on Timeback

If you want to build a new learning app specifically for Timeback, we want to talk to you first. This is a different path from [integrating an existing app](/beta/build-on-timeback/start-building/existing-apps).

<Card title="Book a call" icon="calendar" href="https://app.cal.com/team/timeback-dev/developer-onboarding">
  Schedule a conversation about what you want to build
</Card>

## Why talk to us first

Curriculum gaps exist and must be prioritized.

Before you build, we can tell you:

* Which subjects and grade levels need coverage
* What content standards to align with
* Which learning approaches fit our model
* How to structure your app for [Level 2 integration](/beta/build-on-timeback/integration-levels#level-2-fully-native) from the start

## What this path looks like

<Steps>
  <Step title="Reach out">
    [Book a developer onboarding call](https://app.cal.com/team/timeback-dev/developer-onboarding)
    to discuss what you want to build. We will share current curriculum priorities and gaps.
  </Step>

  <Step title="Align on scope">
    Together we define what your app will cover, which standards it aligns to, and how it fits
    the Timeback ecosystem.
  </Step>

  <Step title="Set up your course structure">
    The Timeback team will help you create your course structure: courses, QTI content, and
    PowerPath configuration. Course builder tooling for self-service setup is in development.
  </Step>

  <Step title="Build with Managed Lessons">
    The SDK's [Managed Lessons](/beta/build-on-timeback/sdk/managed-lessons/intro) handle lesson
    discovery, question sequencing, scoring, and time tracking. You build the UI; the SDK
    orchestrates PowerPath, QTI, and OneRoster under the hood.
  </Step>

  <Step title="Iterate with feedback">
    We review progress and provide guidance throughout development.
  </Step>

  <Step title="Launch on Timeback">Deploy directly to Timeback's distribution channels.</Step>
</Steps>

## Level 2 Integration

New apps built for Timeback start at [Level 2 integration](/beta/build-on-timeback/integration-levels#level-2-fully-native). You use Timeback's systems instead of building your own:

* **[PowerPath](/beta/build-on-timeback/clients/powerpath)** for learning engine and sequencing
* **[QTI](/beta/build-on-timeback/clients/qti)** for content formats
* **[CASE](/beta/api-reference/overview)** for standards alignment

The SDK's approach to **[Managed Lessons](/beta/build-on-timeback/sdk/managed-lessons/intro)** brings these together into a single lesson runtime, handling sequencing, content rendering, and progress tracking so you don't have to wire up each piece yourself.
