Universal Zoom - Science Guide

Universe Scale & Comparison

$4.99 · Designed for iPad

We believe the universe is full of wonders, just waiting to be unlocked, and that this wonder should feel thrilling to curious minds of all ages and backgrounds. Science isn't about memorizing hard numbers. It's about those electric "wow" moments when you truly grasp how vast, tiny, or intricate everything really is. That's why we created Universal Zoom. As a small Canadian team of two passionate science enthusiasts (Andrey on ideas and development, Oksana on graphics and design), we've poured our hearts into this app since 2014. Our mission is to inspire curiosity, from wide-eyed young explorers to educators eager to ignite that same spark in their students. We build with our community in mind: most objects come from suggestions by fans like you, carefully curated for scientific accuracy and paired with stunning real images (high-resolution photos or electron microscope views where possible, like the world's smallest snowman), or original artwork for things that can't be photographed directly (elementary particles, atoms, DNA structures). We stay current through your fact-checks and the latest discoveries. • How we make science feel alive and approachable Dive into beauty and play: scroll endlessly through breathtaking visuals, zooming seamlessly across impossible scales. Then compare (discover how many Earths fit into Jupiter, or how a virus towers over or hides beneath a skyscraper) to turn mind-boggling numbers into instant intuition. Finally, go deeper with polished, jargon-free explanations that read like captivating stories, not dense textbooks. Audio narration supports young readers or anyone who prefers listening. It's like carrying an interactive, ever-growing encyclopedia built by, and for, people who genuinely love science. • What you'll explore From the Planck length to the observable Universe (93 billion light-years), over 270 objects presented to perfect scale: subatomic particles, cells and DNA, animals and iconic buildings, planets, stars, galaxies, and beyond—covering key topics across Physics, Biology, Astronomy, and more. Switch units anytime (metric, imperial, powers of ten, or compare to any object you choose), in 40 languages. No ads, no in-app purchases, just pure, joyful discovery. • For Educators Universal Zoom is a ready-to-use classroom tool that visualizes scale, builds measurement intuition, and transforms abstract ideas into tangible "aha!" moments. Teachers around the world use it for interactive lessons. Contact us for promo codes or get a reduced price on the Apple School Manager for volume purchases. • What's next? With 200+ more community-suggested objects queued up, we're always evolving based on your ideas. Curious about upcoming additions? Follow us for sneak peeks on X, YouTube, and TikTok (@gamifyitapps). Join thousands of fellow explorers. Ready to unlock your own "wow" moments? Download Universal Zoom and start your scientific adventure today. • Feedback?
