Superb

Explore the scale of the cosmos from the galaxies to the atom. The animation, sound design and functionality are incredible.

Why dont you and smaller stuff

Well i want objects like Nothing 0 m
Then 0 Dimensional Space 0 m
And the Protoverse (Anti Universe) 1x10-♾️m

Response from developer

🤩 Thanks for the fun idea — I get the appeal of pushing the scale all the way to "nothing"! The tricky part is that Univerzoom's scale is built on real physical measurements, and Planck length is currently the smallest meaningful unit physics gives us — below that, our current understanding of space itself breaks down, so there's no defined size to place an object at. Concepts like 0-dimensional space or infinity aren't really "sizes" in that sense, so I can't add them as points on the scale the way I can with atoms or subatomic particles. I'll keep an eye on whether there's a fun way to represent that boundary though. Thanks for exploring all the way to the edge!😉

Need more objects

Add more galaxies.Also can you zoom until 1 Planck length (10^-35m)?That would be great.😀360,359,358,357,356,355,354,353,…

Sehr gute App

Vielen Dank an den Entwickler!

Bro change the voice/narration it sound like scorching

Give me updates

Build more updates to the app

Every update needs new objects. The custom object is kept in mind only for you. If you were to create an upcoming update with more objects, I will be glad. THX!

Response from developer

Thank you for following up! Custom objects and more content are great ideas — I can't promise a timeline, but I'm keeping it in mind. Really appreciate the support! 🙏

Great app!

Great app, Linda. For some reason, I can’t see the info about the penny and EU cent. Also, can you please try your best to bring back the original narration voice (Aaron - US)? I understand that it takes time to add more stuff. Your app is amazing regardless what’s in it! 😉 Elise was right. There is a pentagon on Saturn’s North Pole. But it’s your app! You do what you want in it. Thx Elise for pointing that out!

May I list all the errors I could find? I’m going to say the object and the error in the description there was (I hope this helps you! 😉; if I’m being unkind, I’m sorry)

Errors I Could Find (it’s up to you if you want to fix them or not):
• Hydrogen, carbon, and francium atoms: you didn’t capitalise Celsius (no offense)
• Carbon and francium atoms: “chemical” instead of cemical
• Transistor Gate in 2020: you out “theMOSFET” instead of “the MOSFET”
• Clay particle: you put “caly” instead of “clay”
• White blood cell: you put “leucocyts” (did you mean leukocytes?)
• Human: maybe put “is” between ‘women’ and ‘165’ (again, up to you)
• Voyager 1: you put “Jupiter, Saturn.” Did you mean “Jupiter and Saturn”?
• ISS: you put “kilomaters” did you mean “kilometers”?
• Sagittarius A: you put “Sigittarius” at the bottom of the paragraph
• at the “10 Light Years” scale area, you put “Acturus”. Did you mean Arcturus?
• Observable Universe: you put “obervable”

That's all the typos I could find. You don’t have to fix them, it’s up to you. Sorry, if I was being unkind. The app is amazing otherwise!

❤️🤩Thank you for your enthusiasm and detailed suggestions for the app! I’m glad you’re enjoying it. While I appreciate your ideas, adding new content takes time, and I want to make sure each update is well thought out. Please keep your suggestions coming—it's great to hear what users like you want to see! 🙏

개체 너무 적음

10~20개 이상의 개체가 필요 할 것 같고 언어에 한국어도 넣어주세요 직접 두 개체를 비교하거나 만들 수 있게 해주세요.

Response from developer

좋은 평점과 자세한 제안 감사합니다! 오브젝트 추가, 한국어 지원, 비교 기능 모두 훌륭한 아이디어예요. 일정을 약속드리기는 어렵지만, 모든 피드백을 향후 업데이트에 참고하고 있습니다. 정말 감사드려요! 🙏

Custom Object for you

Would you mind adding the custom object feature to the upcoming update of your app UNIVERZOOM 3D? If you do, I would be proud! You said that the user-created content (custom object feature) would be a nice add-on to your app. Would you like to put this custom object update, along with a few new objects, earlier than the future?

Great!

Can you add the atomic scale?

Response from developer

Thanks for the kind words! ❤️😊 I actually have atomic scales all the way down to the Planck length — so I'm curious what you have in mind! Feel free to reach out at support@univerzoom.net and I'll be happy to help.

Nebulae

Hey there!
Could you update the Multiverse?

When you see The observable universe, instead there would be just stuff similar to Cosmic Web but instead have it outside the Universe

After about 10 trillion light years, the multiverse would be visible

Also

Could you add more SI units?
Like
Megameter
Gigameter
Terameter
Petameter
Exameter
Zetameter
Yottameter

And the new ones

Ronnameter
Quettameter
Rontometer
Quectometer

Otherwise, this app is really great!

Response from developer

Thanks for taking time to write such a long review! 🙏🤩that's quite a lot to add. Having fruits is a good idea. To be honest, adding all those galaxies would ruin the current concept of zooming out of the Milky Way, zooming out of the visible universe and beyond. If I would add any other galaxies at that scale, someone would think the location of those galaxies is correct - but their correct location cannot be shown at this scale. 🧐

The animal update

here are the animals and dinosaurs that is allowed at the game
elephant
Sarapod
Tyrannosaurus rex
giant squid

Response from developer

thanks so much for the feedback! I love your list of creatures. As you've noticed, Univerzoom 3D focuses more on the grand scale with planets, stars, and galaxies 🌌! However, all the animals you're looking for (T-Rex, elephant, giant squid) are in my other app, Univerzoom 2D. It's completely focused on life on Earth. It’s a free download, and I think it's exactly what you're looking for. Hope you enjoy it! ✨

PLEASE!

Please change the voice back
To the normal human voice. Nice app though! :)

Response from developer

Thanks for the nice feedback! 😊 Regarding the voice: The app actually uses the voice settings directly from your iOS system. Could you please send me a quick email at support@univerzoom.net describing what you hear? I’d love to help you look into this! 🪐

Universe with no nubulae

There’s no nebulae

Great but mistake

Fix this once again: the distance of James Webb space telescope is incorrect
Current spelling as of December 11, 2025: James web space telescope
Update to: James Webb Space Telescope

Voice Narrator Changes

You need to add Voice Narrator Changes because with only Albert it’s not really that good but that’s all you need to add…

Response from developer

Thank you for your feedback! ☺️ I appreciate you taking the time to share your thoughts. I understand that having only Albert as the voice narrator may feel limiting, and I agree that adding more narrator options could make the experience more enjoyable and personalized. I’ll keep this suggestion in mind for future updates. Feedback like yours helps me understand what users want most, so thank you again for pointing it out. If you have any other ideas or features you’d love to see, feel free to share—I’m always listening!

Mohammed alsabakhi

I heard the sound and it was very scary and then when I tapped on the object, the scary sound spoke and scared me so can you please fix the voice?

Good app

I like this app it’s pretty cool but please change back the icon I liked the old icon instead of this icky AI slop and also you use ChatGPT to respond to reviews

Response from developer

Thanks so much for the feedback and for using Univerzoom 3D! 😊 I’m glad you enjoy the app. Regarding the icon: I appreciate you sharing your preference — design changes can feel unexpected, and input like yours helps a lot. I’ll keep your comment in mind as we continue refining the look of the app. Thanks again for taking the time to let us know! 🙌

Great app!

Great app, Linda. For some reason, I can’t see the info about the penny and EU cent. Also, can you please add it where you can change the text to speech voice? I think the voice in the app (Aaron - US) speaks too fast when reading the complete description. I understand that it takes time to add more stuff. Your app is amazing regardless what’s in it! 😉 Elise was right. There is a pentagon on Saturn’s North Pole. But it’s your app! You do what you want in it. Thx Elise for pointing that out!
