# Testing in AppMaster.io Developer App

Test your app on the fly without having to create a developer account in the stores.

{% hint style="info" %}
Make sure you have saved changes to your mobile app and published the project to a deployment plan before proceeding.
{% endhint %}

1\. Download the AppMaster.io Developer App for Android and iOS from the store.

2\. Log into the Developer App with your AppMaster.io account (the same one you use to log into the AppMaster.io Studio).
