Genymotion

Genymotion is an Android emulator designed for Mac. With its help, you can test your Android apps directly from your Mac, see how they look on a smartphone or tablet screen, and decide which changes need to be made before uploading the program to the Android Play Store.

The app comes with a nicely-designed interface and is compatible with multiple Android OS versions and Android smartphone and tablet models.

You need to complete a couple of steps before using this app. Firstly, you need to download and install an additional tool on your Mac (VirtualBox). The next thing you need to do is to create and log in to a personal Genymotion account (you can create one on the homepage of the developer) in order to get access to a list of virtual devices.

Once the aforementioned steps are completed, you can start creating a virtual device profile. The app lets you choose between multiple types of virtual devices and Android operating system versions. It will then download the necessary data and let you work with the virtual device. You can install your own app on the virtual device, test its capabilities and appearance, etc.

Still, you can find cheaper solutions for testing your Android apps directly from your Mac. It's up to you to decide if it's worth buying this program or not.
