How do I use Calendar Op.2 on a new iPhone?

Calendar Op.2 isn’t tied to your phone number or a specific device — it simply displays whatever is in your iPhone’s Calendar. To set it up on a new iPhone:

1. Download Calendar Op.2 from the App Store.
2. Sign in with the same Apple Account you used before.
3. If your events sync via iCloud (or another account), they’ll appear automatically. Grant Full Access when prompted.
4. If you previously bought Remove Ads, restore it using the same Apple Account — see Ads: removing them, restoring your purchase, and reporting a bad ad.
