The animation, sound design and functionality are incredible. ### 4/5 — Why dont you and smaller stuff *2026-08-11, version 1.2.1* Well i want objects like Nothing 0 m Then 0 Dimensional Space 0 m And the Protoverse (Anti Universe) 1x10-♾️m ### 5/5 — Need more objects *2026-08-10, version 1.2.1* 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,… ### 5/5 — Sehr gute App *2026-07-31* Vielen Dank an den Entwickler! ### 2/5 — Bro change the voice/narration it sound like scorching *2026-07-23, version 1.2.1* Give me updates ### 5/5 — Build more updates to the app *2026-07-07, version 1.2.1* 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! ### 5/5 — Great app! *2026-06-24, version 1.2.1* 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! ### 5/5 — 개체 너무 적음 *2026-06-18* 10~20개 이상의 개체가 필요 할 것 같고 언어에 한국어도 넣어주세요 직접 두 개체를 비교하거나 만들 수 있게 해주세요. **Developer response:** 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! 🙏 ### 5/5 — Custom Object for you *2026-06-16, version 1.2.1* 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? ### 5/5 — Great! *2026-04-25, version 1.2.1* Can you add the atomic scale? ## Frequently asked questions about Univerzoom 3D ### What does Univerzoom 3D do?
