# Test on iPhone or iPad with TestFlight

> Install and update test builds of the FieldKo Atlas app on iPhone or iPad with Apple's TestFlight app.

TestFlight is Apple's app for installing test versions of iOS apps. Use it to try a new version of FieldKo Atlas before it's released in the App Store.

## Before You Begin

* You have a TestFlight invitation for FieldKo Atlas from your FieldKo contact, either an email or a link.
* If FieldKo Atlas is already on your device, sync first. Open the side menu, tap **Sync**, and make sure **Pending Changes** shows 0 records and 0 images.

## Install a Test Build

1. From the App Store, install **TestFlight**.
2. On your iPhone or iPad, open the invitation:
   * **Email invitation:** Tap **View in TestFlight**, and then tap **Accept**.
   * **Link:** Open the link, and then tap **Accept** in TestFlight.
3. In TestFlight, next to **FieldKo Atlas**, tap **Install**.
4. Open FieldKo Atlas and log in.

The test build replaces the App Store version on your device. It shows an orange dot next to its name on the Home Screen.

## Update to a Newer Test Build

TestFlight notifies you when a new test build is ready. Sync first, and then open TestFlight and tap **Update** next to **FieldKo Atlas**.

Each test build expires 90 days after it's released. When a build expires, it stops opening. Install the latest build from TestFlight, or go back to the App Store version.

## Send Feedback

* **From the app:** Take a screenshot while using FieldKo Atlas, tap the preview, tap **Share Beta Feedback**, add a comment, and tap **Submit**.
* **By email:** Email [support@fieldko.com](mailto:support@fieldko.com) with the details listed in [Report a Problem](/mobile-testing/test-new-versions#report-a-problem).

## Go Back to the App Store Version

1. In FieldKo Atlas, tap **Sync**, and make sure **Pending Changes** shows 0 records and 0 images.
2. Open [FieldKo Atlas on the App Store](https://apps.apple.com/us/app/fieldko-atlas/id1605506891), and tap **Get** or **Update**.

You can also stop testing in TestFlight: open **FieldKo Atlas**, and then tap **Stop Testing**.
