To find and manage your subscriptions on an iPhone, follow these steps:

1. Open the Settings app.
2. Tap your name at the top to access your Apple ID settings.
3. Tap Subscriptions.

Here, you will see a list of all your active and expired subscriptions purchased through Apple and the App Store. You can tap any subscription to view details, change plans, or cancel it if desired

. Alternatively, you can also access subscriptions via the App Store app:

1. Open the App Store.
2. Tap your profile icon in the top right corner.
3. Tap Subscriptions.

This will bring you to the same subscription management screen where you can view, renew, or cancel subscriptions

. If you do not see a subscription listed, it might be managed outside the App Store (e.g., directly through the service provider’s website), so you may need to check your email receipts or bank statements for those subscriptions

. In summary, the primary and easiest way to find subscriptions on an iPhone is through Settings > [your name] > Subscriptions or through the App Store > profile icon > Subscriptions
