subscription This app charge me 49.99 $ I want Cancel it please

We cannot cancel anything for you. This is a user to user only forum.

You can cancel the subscription by following the directions in this link --> How to cancel a subscription from Apple - Apple Support

When you followed the link in the previous post what did you see? If you are not familiar with links, a link on a web page is a way open a new page with additional information. A Link is usually shown as blue text, and to open the new page position your mouse cursor anywhere within the blue text (the mouse cursor will turn into an hand) and click the left mouse button.  Let me show an example:

                                 CLICK HERE

                                    \/

CLICK HERE—>How to cancel a subscription from Apple - Apple Support<—CLICK HERE

                                    /\

                                CLICK HERE

Do you not understand we are users like you? We don't work for Apple. We can't cancel your subscription. I gave you a link you seem to refuse to click on to learn how to cancel a subscription. I can't cancel anything for you.

Since this seems too difficult for you. Click the Get Support button at the top of this page to ask Apple for help.

Again, I don't work for Apple, so I can't cancel your subscription. I gave you a link (words in blue) for you to open to learn how to cancel the subscription yourself.

Follow the instructions by clicking the link in the post you marked as Solved.

EASY WAY go to settings up at the top where it tells you who you are press if you scroll around you will see subscriptions press and 💥 boom you have every single subscription you currently have!
