# Platforms

Platform targeting enables you to display your ads to users based on the type of device they are using. This is beneficial for ensuring compatibility with your product or service and tailoring your campaign to specific user experiences across different platforms.

We categorize devices into the following groups:

• <mark style="color:green;">Web</mark>: Includes users of the Telegram web version and desktop applications.

• <mark style="color:green;">iOS</mark>: Includes users of the Telegram app on iPhones and iPads.

• <mark style="color:green;">Android</mark>: Includes users of the Telegram app on Android mobile devices and tablets.

**Cost**: when enabled, the user‑defined cost per click (CPC) or cost per 1000 impressions (CPM) is increased by 50%.
