Advent Calendar OpenGLEffects vs Advent App

This is a beautiful designed Advent Calendar with OpenGL Effects, see what cool effects can be done on the iPhone/iPad day by day. See 3 Dimensional Galaxies, and great stuff each day. These are not just simple images, these are moving particles! A really great show you should not miss! Behind some doors your interaction is needed (tap the screen,etc...) Also with some christmas music. I hope you will enjoy it

Create a personal Advent calendar and gift it to someone you love: 24 doors filled with photos, videos, voice messages and little surprises, opening one by one in December. Newly redesigned for 2026: fresh calendar designs, a warmer, calmer look, voice messages behind any door, and full iPad support with iCloud sync — in 17 languages. Why you'll love the Advent App Doors made for your loved one Fill every door with your favorite photos and videos, a special song, a voucher, a funny quote, or a little memory you know they'll smile about. Fill it your way, not all at once Because the calendar is digital, you don't need to finish everything by December 1. Add doors as you go and update them whenever you like. Gentle reminders so you never miss a day If you enable notifications, we'll send you a little reminder the day before each door opens. No account needed When you create your calendar, we generate a custom link you can send to your loved ones via WhatsApp, SMS or email. No sign-up for anyone — they simply download the free Advent App, tap your link, and their calendar is ready. Share with as many people as you like One calendar, one link — send it to one special person or the whole family. Gift it ad-free — or send it for free Sending an ad-free calendar is a one-time purchase per calendar — no subscription. And if you'd rather not pay, there's a free option too: your loved one simply watches a short ad before opening each door. Have fun creating and gifting, and have a tree-mendous holiday season!
