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.

Verdict

The call

The clearest difference is rating: Universal Zoom at 4.8 against Powers of 10's 4.2. Universal Zoom also leads on ratings volume (356 vs 11). Powers of 10's advantage is price ($0.99 vs $5.99) and iOS requirement (11.0 vs 15.5). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Universal Zoom holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Universal Zoom has 356 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 97% of Universal Zoom's written reviews are positive against 100% of Powers of 10's, so the app with the better star average is not the one people write more warmly about.
