Why lately, when I purchase an app with a trial do I get charged immediately? Is it a free trial!?

Hi Tonex50,

welcome to the Apple (user-to-user) Community.

Seems, in general, free trials need to be cancelled at least 24 hours before the free trial ends, if you do not want to be charged.

The charge may be for the current month, after the free trial ends, and there would then be monthly subscription charges to follow, often for the month ahead.

What to do:

If you want to cancel a subscription from Apple – Apple Support

or

If the subscription that you want to cancel is not listed – Apple Support

More info: About cancelling subscriptions in Germany, Israel, South Africa or Turkey – Apple Support

If you were charged earlier than 24 hours before the trial ended:

You can: Find the URL for an app in the App Store to report a concern - Apple Support

or

If the free trial is from Apple, you can report a problem to Apple:

or

To request a refund: the "Related article" above your question gives details

All the best :-)
