Works best for Ipad. TopMod is a topological mesh modeler for sculpting intricate, high-genus 3D surfaces right on your iPhone and iPad. Build handles, holes, and complex manifold geometry in real time, then export your creations as OBJ files to use in any 3D pipeline. A focused, self-contained tool for artists, designers, and anyone who loves the mathematics of form.
Orbit
Experience a serene, interactive 3D model of our solar system. Watch planets orbit, zoom in for detailed views using NASA-based maps, and explore celestial scales and distances. Enjoy a calming, ad-free, and offline visual journey.
- Interactive 3D solar system model
- NASA-based planet textures
- Accurate Kepler orbits (1800-2050)
- Adjustable time speed
- Scale comparisons (distance, size, sunlight)
- Offline functionality
- Ambient sound option

Set your phone on the desk, turn it landscape, and let the solar system quietly come to life. The Sun breathes. The planets trace their orbits. The stars settle into the dark. Ten worlds, up close. The Sun, all eight planets, and the Moon — rendered from 2K NASA-based maps. Earth's drifting clouds and city lights, Saturn's shadowed rings, a living, glowing Sun. Drag to spin, pinch to zoom, and get close to each one. Orbits in motion. The planets follow JPL-based Kepler orbits across the years 1800 to 2050. Pause, play, or speed up time — from six hours to a full year every second — and watch the whole system dance. See the true scale. Line the planets up two ways: an easy-to-read layout, or their real average distances to scale in AU. Then compare sizes, the length of a year, and how long sunlight takes to reach each world. A quiet place to linger. Leave it running and, after a while, the controls fade away — just the planets, slowly turning. A single tap brings them back. An optional, softly synthesized ambient tone can play along, even with your phone on silent. Chinese & English. Switch languages anytime — the science, comparisons, and sources all come with you. No ads. No subscriptions. No account. Orbit runs fully offline and keeps nothing about you. The solar system, on your desk — quietly turning, always there.

Verdict
TopMod and Orbit are too close to call on the numbers: across 6 compared parameters — price, ads, in-app purchases and monetization model among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
