Hi there! Yes, you can definitely use Puzzle Page on your iPhone! Since you’ve already subscribed on your iPad, you can install Puzzle Page on your iPhone as well.

Here's how to get started:

1. Download the App: Open the App Store on your iPhone and search for "Puzzle Page". Download and install the app.

2. Log in with the Same Apple ID: Make sure your iPhone is logged in with the same Apple ID that you used on your iPad. This is important for syncing your subscription and progress across devices.

3. Cloud Saving Feature: Puzzle Page uses iCloud saving by default. When you install it on your iPhone, your game progress should sync automatically as long as both devices are under the same Apple ID and iCloud settings are enabled.

If you have any trouble, make sure your iCloud is set up correctly on both devices. You can check this by going to Settings > [Your Name] > iCloud, and ensuring Puzzle Page is toggled on.
