# Spark iOS setup

> Install the Spark iOS app on your iPhone or iPad and connect to your Spark web app scenes

The Spark iOS app is the iPhone and iPad companion to the Spark web app. It turns your device into a virtual camera inside the same scenes you build in the browser. Both apps share the same real-time database — move an asset in the browser and the phone sees it, move it on the phone and the browser sees it.

## Prerequisites

* An iPhone or iPad with [the Spark iOS app installed via TestFlight](https://testflight.apple.com/)
* A Spark account, signed in first on the web
* A 3D scene already set up in the Spark web app

<Note>
  The Spark iOS app is currently distributed through TestFlight. App Store availability is forthcoming.
</Note>

<Warning>
  Sign in on the Spark web app before opening the Spark iOS app. Opening the iOS app before your web account exists is the most common cause of access problems for new users.
</Warning>

## Sign in

1. Open the Spark iOS app on your iPhone or iPad.
2. Sign in with the same Google or Apple account you use in the browser. There is no separate phone login — your organization, productions, scripts, scenes, and shot lists follow your account.

## Navigate to a scene

1. Select your organization from the home screen.
2. Open your production.
3. Navigate to the script scene, then tap into the 3D scene you want to work in.

The scene loads with all assets, locations, and shots that exist in the Spark web app.

## Splat size limits

The Spark iOS app caps at roughly 5 million splats per scene. If your splat exceeds that count, the scene will not load on the phone. Keep a downsampled version for mobile previs and the full-resolution version for the browser and for Jetset on set.
