Hi @slider9499,
Thanks for posting here at the Roku Community!
We'd be more than happy to assist you regarding your concern.
Like you access an “app store” on your smartphone to add new applications, you access the Roku Store to add new channels or apps to your Roku streaming player or Roku TV. Some apps require a paid subscription or a one-time charge, while many others are free.
You can browse for apps/channels on Roku Channel Store, make a subscription, and add them to your device/TV.
If you need further clarification and assistance, let us know!
Warm regards,
Carly
