The universe is endlessly vast. A single atom is impossibly small. And somewhere between those two extremes lies everything that has ever existed.
We believe that feeling — the electric, spine-tingling sense of scale — belongs to everyone. Not just scientists. Not just students. Everyone.
That's why we built Universal Zoom.
WHAT YOU CAN DO
• Zoom seamlessly from the Planck length to the edge of the observable universe — about 300 objects presented to perfect scale.
• Compare any two objects side by side: how many Earths fit inside Jupiter? How does a virus measure up against a skyscraper? Instant, visual, intuitive. (No other scale app lets you do this.)
• Go deeper with audio narration and short, accessible explanations — the facts that matter, in plain language.
WHAT YOU'LL EXPLORE
• Elementary particles — quarks, leptons, and bosons. Atomic nuclei, atoms, and DNA. Living cells. Animals and landmarks. Planets, stars, and galaxies. A deep dive into physics, biology, and astronomy — with short, plain-language articles that make even particle physics easy to grasp — in 40 languages, with metric, imperial, or powers-of-ten units.
• Real high-resolution photos and electron microscope images, where possible. Original artwork for things that can't be photographed — like elementary particles and DNA structures.
• No ads. No in-app purchases. Pure discovery.
BUILT WITH YOU
We're a team of two (Andrey and Oksana) from Canada who have poured a decade into this app because we genuinely love science. Most objects come from community suggestions — carefully fact-checked and updated with every new discovery. Over 200 more are already in the queue.
FOR EDUCATORS
Used by teachers worldwide to visualize scale, build measurement intuition, and turn abstract numbers into "aha" moments. Available at 50% off for schools via Apple School Manager (20+ copies).

This app is amazing and I would highly recommend it to someone who is curious about our planet. It gives very insightful information to the reader and has blown my mind with information I didn’t know! One request I have is for the creators to add a blue whale, to compare it to other mammals as it is the biggest mammal on earth.
Developer Response
Thank you for your suggestion. We added a blue whale in update 2.5.
Incredible UniversalZoom
oort cloud 4098
Universal zoom is an incredibly amazing app where you can look at a size comparison of our universe! You can compare things to other things without needing to look at loads at once! If you love size comparisons this app is for you! You WILL LOVE IT! It’s so good and fun. So get it if you can.😮🙂
Beautifully made, very interesting

Shows you how tiny/vast everything is. Works great. Very well made, plus ambient music, and nice info. Recommend for a mind-expanding trip into, and around, the universe 😲🤔🤯👍
Make nebulas and galaxies
make more stuff in the game
I want nebulas and galaxies because that’s the only way for me to give five stars and the biggest star Stephenson 2-18in the game and more nucleus and more viruses and more mountains they all can be in diffrent updates or put them all in a update
Developer Response
Thanks for your review. During 2025-2026, we added many Nebulas, more mountains, more viruses, and many more. Btw, Stephenson 2-18 was in the app for years. Check out the recent update. Feel free to update your rating and review. Cheers! Enjoy! 😊
Version 3.0 is our biggest expansion of the Physics part of the app yet.
• A whole new kind of object — point particles like quarks, leptons and bosons. Having no measurable size, they stay put as you zoom instead of growing or shrinking.
• 39 objects added or significantly improved — point particles, plus more atomic nuclei and atoms, and a handful of larger objects too.
• Particle physics is a tricky topic, so we added 5 short articles that explain it in a simple, easy-to-follow way — with many more articles to come.
• We improved the information for many objects, refreshed the images for several of them, and polished translations and voice-over pronunciation.
• We fine-tuned the soundtrack volume based on your feedback.
Thank you for your continued feedback — it truly helps make Universal Zoom better with every update!
