PDF Expert 7 is free to download, but it also offers a PRO pack with PDF superpowers like text editing, page management, and redaction.
Note: If you've previously purchased PDF Expert 6, you can still use all the features you had, without a subscription.
The PRO pack is available at $49.99 per year. PDF Expert 7 offers a free 7-day trial so you can decide if the paid features fit your needs.
The payment will be charged to your iTunes account. The subscription renews automatically until you cancel it.
You can cancel a subscription anytime in the Settings of your device at least one day before each billing date.
