Yes! You can use any app that you wish. While we do offer our own CowboyIPTV app, you are not required to use that specific app. Tivimate is by far the most popular and customizable app for Android powered devices like Fire Sticks and Android boxes. If you are using an apple device, one of the best available apps is UHF, but there are other great options available as well, such as iPlay and IPTVX.
When using the CowboyIPTV app, you only need to enter your username and password because all other settings are built directly into the app like DNS settings.
If you are using a third party app such as the ones we mentioned above, you will need to enter in our service URL along with your username and password. All this information is available in your welcome email as well as I'm your online account under "My Services" at http://cowboyiptv.net/billing
While you can use any app to access your service, just be aware that we can only provide basic troubleshooting as we do not directly support any third party app. If you are experiencing issues accessing your service and are using a third party app like Tivimate, then we suggest you install the CowboyIPTV app and see if you can access your service. This will help diagnose the issue. If you can login and stream via the CowboyIPTV app but not on your third party app then the issue is with the app itself or the setup.
