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.

Tuning Fork Effects EduTech is an interactive learning app designed to help students understand the effects of a vibrating tuning fork. Through clear explanations, engaging visuals, and activity-based demonstrations, the app makes learning about sound vibrations simple and fun. Students can explore how a tuning fork produces sound, how vibrations propagate through different mediums, and how sound waves interact with the environment. The app features 3D interactive models that can be zoomed, rotated, and explored offline, making physics concepts easier to visualize and understand. Ideal for school-level physics, the app helps learners grasp the fundamentals of sound, vibration, and wave propagation with an interactive and hands-on approach. Features: - Interactive 3D tuning fork models with zoom & rotate - Learn how vibrations produce sound - Understand wave propagation and effects - Clear, student-friendly explanations - Works completely offline - no internet needed - Activity-based visuals for deeper understanding - Perfect for school physics and sound experiments Explore the fascinating world of vibrations and sound with Tuning Fork Effects EduTech, your interactive guide to learning physics effectively.

Verdict
The clearest difference is update cadence: Universal Zoom at every 4 months against Tuning Fork Study's every 37 months. Tuning Fork Study's advantage is price ($1.99 vs $5.99) and iOS requirement (12.0 vs 15.5). On ads, in-app purchases and device support there is nothing between them.
