Join the era of spatial messaging — with a library of 3D reactions for Messages. Like a GIF, emoji, or sticker, but in augmented reality. When the moment’s right, pop open Greetings From Space and find the perfect spatial reaction — we call them hologlyphs — from the dozens you’ll find in the app. Send it with a tap through Messages to your other friends with an iPhone. Wherever they are — at their desk, on the subway, the bathroom stall — it invades their physical space in augmented reality 3D with just a tap. You may be the GOAT of GIFS, you slay at emoji, and you’ve got your tapbacks, memes, and stickers on lock. But isn’t it all feeling a little… two-dimensional? Say it with a hologlyph. Send it like a GIF, but it pops into the real world in full 3D. Wield the perfect punchline with a library full of hologlyphs to choose from. Side-texting your work bestie while your boss’ lecture implodes? Drop in some “going off the rails” vibes with a runaway train. Partner checking in on your day after late-binging Severance? You’re “just phoning it in”… on a phone. From Happy Birthday to Marry Me, or just one massive eye roll, there’s a hologlyph for the moment. Dozens to choose from and more to come. Greetings From Space runs on iPhone, iPad, and Apple Vision Pro. Send a hologlyph and they open right in Messages, no app required on the other end — as long as they’re a blue bubble too. Get a handful for free. Then grab the booster pack for $1.99 to unlock over 50 more hologlyphs. One-time purchase. Family Sharing included.
